### Heat Tiles

<figure><picture><source srcset="/files/onQnPU34eWF4sA76k3lw" media="(prefers-color-scheme: dark)"><img src="/files/FfC0KTjhKmiZrEgG7OXN" alt="Heat tiles"></picture><figcaption></figcaption></figure>

**Heat tiles show an instant overview of your network and services.**

Heat tiles are more than a simple traffic light system. They have built in intelligence and work like a fuel gauge. Degraded service drives the colour change through amber to red. They represent the current status of each location or service and are a combination of many monitored elements summarised as three key metrics: **Stability, Load and Health**

Find out more about [heat tiles](/status/network/heat-tiles).

***

#### Service tiles

Allow watches from any location in your network to be grouped into a single tile, custom-define thresholds to change tile colour based on the total number of issues. &#x20;

<figure><picture><source srcset="/files/LrntAqB3iUv0NfKKqXds" media="(prefers-color-scheme: dark)"><img src="/files/Zw7g5o16RjAe5Ia367MT" alt="Service tiles explained"></picture><figcaption></figcaption></figure>

***

#### Location tiles

Every location within your network is shown as an individual tile. Indicators show the duration and state of an issue. Up chevrons show a continuing issue and down chevrons show an issue returning to a healthy state.

<figure><picture><source srcset="/files/acfuYkJdGa03rYPunAmY" media="(prefers-color-scheme: dark)"><img src="/files/Tqbw3ulk3RgR6jww7YnG" alt="Location tiles explained"></picture><figcaption></figcaption></figure>

### Grid view

<figure><picture><source srcset="/files/OqvVfHe9E25f4t6SqkX4" media="(prefers-color-scheme: dark)"><img src="/files/M5kDSvtEHt94QfbwggQI" alt="Grid view image"></picture><figcaption></figcaption></figure>

Highlight's Grid View offers an alternative way to view your locations and folders by categorising services into Underlay, Overlay and LAN columns:

* scan across rows to see the status of different services at a location
* scan down columns to see, at a glance, if issues are occurring with particular services
* sort by service to find the most recent issues
* use Group by folder to see multiple locations represented as a single folder - useful for service providers to quickly check on the status of many customers

Find out more about[ grid view](/status/network/grid-view).

### Alerting

#### Alerts trigger immediate emails, webhooks or traps if there are problems with your network or services.

<figure><picture><source srcset="/files/p6DjyN6ZzsZIs0ZBqT7k" media="(prefers-color-scheme: dark)"><img src="/files/RMXAK4toJwRetOENHRcm" alt="Alerting table"></picture><figcaption><p>Alerting table</p></figcaption></figure>

Located in the Status area, alerting will allow you to create alerts and define when, how, and to whom notifications are sent. Specify whether you want notifications outside business hours, who should be informed (mailing lists or multiple email addresses can be configured) and which folders/locations are to be included.

**There is no limit to the number of alerts so create as many as you require**

Read more about [alerting](/status/alerting/alerting-email).

***

#### Alerting sensitivity

<figure><picture><source srcset="/files/GmPHc4NVlBtmfxfli8Hw" media="(prefers-color-scheme: dark)"><img src="/files/YTQyvHRSF81FCkeSaj9a" alt="Sensitivity panel"></picture><figcaption></figcaption></figure>

Also visible on the Alerting page is the sensitivity panel. This shows how quickly Highlight will change the colour of heat tiles and send alerts for stability, load and health issues.

Read more about [sensitivity](/status/alerting/sensitivity).

### Reporting

<figure><picture><source srcset="/files/vLyBcgzMG7yMK3Gqohxh" media="(prefers-color-scheme: dark)"><img src="/files/nLindk8SEsAYWmrObRBF" alt="Reporting Insights"></picture><figcaption><p>Reporting Insights</p></figcaption></figure>

#### The latest trend: Highlight Reporting Insights

Use Reporting Insights to:

* View reporting data graphically

# Glossary

### Highlight terms A - M

#### Activate <a href="#activate" id="activate"></a>

After a device is fully deployed and tested, 'activate' makes the device live for monitoring on Highlight, previously referred to as 'promote'.

#### Agents <a href="#agents" id="agents"></a>

A server running Highlight software that provides a framework for managing Highlight tasks such as device polling, flow collection and performance testing. Results are compiled and sent back to the main Highlight system for presentation and archiving. Devices monitored by Highlight do not use agent software.

#### Application Domain <a href="#application_domain" id="application_domain"></a>

An application domain comprises a folder and all its subfolders. All users in those folders see the same AppVis groups. Typically an application domain is set at the top folder for an entire customer organisation.

#### Alert <a href="#alert" id="alert"></a>

Sent via email or SNMP trap to make someone aware of issues on the network. Alternatively, use a webhook to integrate into service management systems.

#### Alerting Metrics <a href="#alerting_metrics" id="alerting_metrics"></a>

These are referred to as level 3 metrics in Highlight. **See also:** [Alert messages](/status/alerting/alert-messages)

* **Stability:** a measure of outages and availability issues (availability is measured over time, as a percentage and stability relates to whether an element is up or down)
* **Load:** a measure of traffic utilisation on a circuit or other device
* **Health:** a measure of performance problems, packet discards, line errors and signal problems (WiFi only)

#### Bearer/Access Circuit <a href="#beareraccess_circuit" id="beareraccess_circuit"></a>

Like a pipe to transport data - the pipe can be partitioned to fast and slow sections, can be up or down and can be heavily or lightly loaded.

#### Business Hours <a href="#business_hoursworking_hours" id="business_hoursworking_hours"></a>

The time periods (to the nearest hour) that a business is operational, say Monday – Friday 9am to 5pm; used when displaying traffic trend graphics, for filtering report results, and when generating alerts.

#### CCD

CCD stands for **Core Class Definition**. It is a list of class names which are in use on the service provider's network, used to configure Highlight to collect and report on Classes of Service.

#### Chevron <a href="#chevron" id="chevron"></a>

Part of a [heat tile](/getting-started/new-user/glossary#heat_tile), coloured amber or red and showing issues are improving (pointing down) or deteriorating (pointing up) as trends (performance over time).

#### Collector <a href="#collector" id="collector"></a>

A server which has the function of receiving data being sent by monitored devices e.g. Flow.

#### Containers <a href="#containers" id="containers"></a>

&#x20;A flexible, customised grouping of watches which can be put into one-off or recurring maintenance, displayed as a service tile or used as the basis of a report.\
**Related terms:** [Watch](/getting-started/new-user/glossary#watches), [Maintenance](/getting-started/new-user/glossary#maintenance_mode)

#### Contextual Help <a href="#contextual_help" id="contextual_help"></a>

When clicking the '?' on each section of the Highlight UI, a link opens specific Help & Support Centre page or section to provide information relevant to that area of Highlight.

#### Controller Status watch

A parent controller may have hundreds of associated subwatches in the form of uplinks, tunnels, performance tests, etc. To limit alert spam, Highlight offers the option to suppress alerts on subwatches if the parent controller is uncontactable. Previously, this meant no alerts were sent if the controller was down. The controller status watch was designed to resolve this issue.

All controllers have a controller status watch created automatically. Alerts configured as 'all watch types' will send stability alerts if the controller is down. Alternatively, a specific alert for controllers only can be created.

#### DBA: Dynamic Bandwidth Adjustment <a href="#dbadynamic_bandwidth_adjustment" id="dbadynamic_bandwidth_adjustment"></a>

Highlight will check and update the bandwidth as part of the 'Device Validation' process for a router, which happens each time a router configuration change is detected, or every 24-48 hours if not.

#### Domain <a href="#domain" id="domain"></a>

A folder in Highlight, and its subfolders, which is associated with a specific login URL. All user accounts in a domain have to be unique but duplicate user accounts can be configured on several domains, allowing access to disparate parts of the Highlight tree.\
**Similar term:** [Application Domain](/getting-started/new-user/glossary#application_domain)

#### Dormant <a href="#dormant" id="dormant"></a>

Bearer watches can be set as dormant in the [Edit Watch dialog](https://support.highlight.net/help/admin/edit_watch#main_tab_lower_sections) or in the [SD-WAN Edit Watch dialog](https://support.highlight.net/help/admin/sdwan_items#edit_watch_main_tab). Dormant interfaces only send stability alerts if the device is uncontactable or Highlight has detected that the underlying connectivity service is unavailable.

#### Exception <a href="#exception" id="exception"></a>

Seen in Highlight's historical reporting. When any metric Highlight is monitoring (for example Load or Response Time) exceeds its target threshold for a certain length of time, it generates an **Exception** and causes the watch and its associated location tile to change colour (green to amber and then red). The watch now stays in this ‘Exception’ state until the metric returns to normal. The [Exceptions report](/reporting/network-reports/colours#exception) counts the total number of times this watch went into an Exception state and the total time it spent in that state in hours and minutes.\
**See also:** [Reporting exceptions](/reporting/network-reports/colours#exception)

#### Favourites <a href="#favourites" id="favourites"></a>

Custom defined, frequent use elements in Highlight.  **See also:**  [Favourites](/getting-started/useful-information/network-explorer#id-2-favourites)

#### Heat tile <a href="#heat_tile" id="heat_tile"></a>

Coloured green, amber or red to show if performance is within or exceeding thresholds used for locations and services. **See also:** [Heat tiles](/status/network/heat-tiles)

#### Issue Score <a href="#issue_score" id="issue_score"></a>

An Issue Score is a number from 0 (good, no issues) to 10 (bad, lots of issues) which provides a simple way to see how good or bad a location was during the selected time period and to compare it with other locations. Issue Scores are an aggregation of several metrics. Values are adjusted logarithmically so that small-medium problems push the score up quickly, and it then levels off.\
**See also:** [Reporting issue score](/reporting/network-reports/colours#issue-score)

#### Link-availability <a href="#link-availability" id="link-availability"></a>

Relates to the current up/down state of a watch when monitoring Link Health, WAPs or Performance tests. Affects the Stability metric of the heat tile.\
**Related term:** [Link-stability](#link-stability)\
**See also:** [Problem text in Alerts](/status/alerting/alert-messages#problem-text-in-alerts)

#### Link-stability <a href="#link-stability" id="link-stability"></a>

Relates to changes in the state of a device between samples when monitoring Link Health. Affects the Stability metric of the heat tile.\
**Related term:** [Link-availability](#link-availability)\

#### Performance Test <a href="#performance_test" id="performance_test"></a>

A stand-alone network test associated by Highlight with a bearer or a child watch (class of service or VLAN, for example). The actual test source can be any Highlight reachable device capable of running tests.

#### Poller <a href="#poller" id="poller"></a>

A server with access to a customer's network that validates monitored devices and performs the gathering of statistics via SNMP.

#### Polling cycle <a href="#polling_cycle" id="polling_cycle"></a>

The interval between consecutive SNMP requests from Highlight for information from a watch. Typically every 3 minutes but can vary by partner. This is shown as **Poll Frequency** on the [edit watch dialog](https://support.highlight.net/help/admin/edit_watch#main_tab_lower_sections) and as **Poll (secs)** in the [Admin watch report.](https://support.highlight.net/help/reporting/admin_reports#watch_report)

#### Reporting API <a href="#reporting_api" id="reporting_api"></a>

The Reporting API makes it possible to view Highlight’s summarised data, device inventory and watch folder/location information outside the Highlight Service Observability Platform. Read more about the [Reporting API](/reporting/reporting-api).

#### Subwatch <a href="#subwatch" id="subwatch"></a>

See watch. Also known as 'child watches,' these are discovered watches such as Classes of Service, VLANs and WAPs or created watches such as performance tests. These are typically displayed in Highlight with the parent bearer.\
**Related term:** [Watch](#watches)

#### Technical Test ("Tech Test") <a href="#technical_test_tech_test" id="technical_test_tech_test"></a>

A test to confirm the configured IP address with security credentials provided is reachable and responsive, used in Admin Pending, when adding a Performance Test, with Application Visibility and when editing a watch to change interface.

Found in Reporting and Details pages, use to select a given period: any day, week, or month for the past year.  Also referred to as the Calendar control.

#### Visibility <a href="#visibility" id="visibility"></a>

The visibility setting is applicable to bearer watches, service tiles, folders and alerts and is only shown if you are a service provider administrator. Visibility determines if a service tile, folder or alert will be visible to all users and customers or just to service provider internal staff. There are two options:

* **Customer:**

  anyone can see the item (this is the default setting)
* **Internal:**

  the item is only visible internally (for the service provider)

**See also:** [Bearer Watch Visibility, ](https://support.highlight.net/help/admin/edit_watch#main_tab)[Folder Visibility (referred to as Category) ](https://support.highlight.net/help/admin/create_tree#create_a_folder)and [Alert Visibility](/status/alerting/alerting-email#create-alerts)

#### Cookies Policy

The Service uses cookies to improve the experience of its users. This usage includes, but isn't limited to, remembering your login name (email address) and preferences, between sessions. A cookie is a small file of letters and numbers that the Service puts on your computer when you log in.

We may revise these terms of use at any time by amending this page. Please check this page from time to time to take notice of any changes we made, as they are binding on you.

#### Data Integrity

Highlight strive to ensure that collection of data by Highlight is contiguous and continuous. Advertised "downtime" of the Service normally means that the Web Interface will be unavailable for the stated time, but that data collection will continue unchanged and when access to the Web Interface is restored, there will be no gaps in collected data. On the rare occasions when collection of data needs to be temporarily suspended, this fact will be advertised.

Information displayed by Highlight is based on data collected from devices over which we have no control. We make every effort to ensure the information displayed by the Service is accurate, but Highlight is not responsible for inaccuracies caused by faulty software or firmware in devices being monitored, or for problems caused by network connectivity over which we have no control. You assume responsibility for the use you make of the data provided by Highlight. Where the Service contains links to other sites and resources provided by third parties, these links are provided for your information only. We have no control over the contents of those sites or resources.

#### Limitation of Liability

Nothing in these terms of use excludes or limits our liability for death or personal injury arising from our negligence, or our fraud or fraudulent misrepresentation, or any other liability that cannot be excluded or limited by English law. To the extent permitted by law, we exclude all conditions, warranties, representations or other terms which may apply to the Service or any content on it, whether express or implied. We will not be liable to any user for any loss or damage, whether in contract, tort (including negligence), breach of statutory duty, or otherwise, even if foreseeable, arising under or in connection with:

* use of, or inability to use, the Service; or
* use of or reliance on any content displayed on the Service.
* loss of profits, sales, business, or revenue;
* business interruption;
* loss of anticipated savings;

Questions, comments and requests regarding this privacy policy are welcomed and should be addressed to <support@highlight.net>

### 2. Personal Information: Data Protection and the GDPR

#### Our Privacy Policy

This section describes how we handle Personal Data for you as a user of the Highlight service (the Service). We’ll describe it in general terms, and specifically as it’s covered in the Data Protection Act 1998 (the DPA) and the General Data Protection Regulation 2018 (the GDPR).

#### In summary

Our policy around your personal information is this : We will work hard to protect your privacy, and we will only collect, keep and use information about you which enables us to:

* Carry out our obligations to you as a user of our Highlight Service
* Tell you about changes to the Service which might affect your use of it (for example, if Highlight is going to be unavailable for maintenance)
* Tell you about changes to the Service which might help you get more out of it (for example, describing a new feature we’re adding, or reminding you about a feature we think would be valuable to you)
* Store your preferences in using the Service, and details of how you have used it
* Understand and record how people use the Service, both to help us improve it, and to provide audit trails of changes as part of the Service’s Administrative functions

Processing of personal data is incidental to the Service, and not our primary purpose, and we will regularly audit that your data is stored securely. We will never pass your information on to third parties unless it both supports one of the goals above, and is being passed to an organisation which has confirmed it will treat your data to the same standard we do and complies with the DPA / GDPR.

For the purpose of the DPA or the GDPR, Highlight (SLM) Ltd functions as both a data controller and data processor. If you have any further queries about how we process your data, or what data we hold on you, you can contact us via the phone numbers at the foot of this page, which are also found on our website, [www.highlight.net](https://www.highlight.net/). You can also send emails to <gdpr@highlight.net> where they will be routed to the appropriate person.

#### The Details

#### Information we may collect from you

We may collect and process the following data about you:

**1. Information that you provide when you register to use the Service, or when someone in your organisation or service provider registers you to use the Service :**

* Your Email address, which enables us to identify you to Highlight, store your preferences for using the system, and send you emails about the Service;
* Your Full Name, which we use to include in reports, to help other people in your organisation or your service provider identify you, and
* A phone number we can use to contact you (optional)

Your email and full name are necessary for correct functioning of the Service, and if you don’t provide them you will be unable to access the Service. This information will be stored for as long as you have an account on the service. If you stop using your Highlight account, your account details will be automatically deleted after twelve months, although we will retain abbreviated details about you (your email address) in audit and system logs for up to three years. If you want to change the details we hold on you, or delete your account, and don’t have the necessary privileges to do it yourself, you can contact:

* Your Service Provider’s support desk, if Highlight was set up for you by a Provider, or
* Highlight’s support team on <support@highlight.net>.

Your email address will be used to send you administrative details and updates about the Service, for example to notify you of outages, or tell you about new features. These emails will always contain an “unsubscribe” link although we recommend that you stay subscribed as you may miss important information, or not be aware of important changes or enhancements to the Service that you might find valuable.

**2. Information on your usage of the Service :**

* The date, time and IP address from which you log in to the Service
* The date, time and IP address from which you make administrative changes if you have those privileges

We keep this information for security purposes, to help us understand how people use the Service, and to help other people in your organisation or your Service Provider make best use of the service and understand how it has been used. This audit-trail information is available through the Highlight GUI to people who administrate your account. The audit trail information will be kept for two years after your Highlight account is deleted, and then automatically purged.

**3. IP Addresses**

We may collect information about your computer, including where available your IP address, operating system and browser type, for system administration and to help us understand how people use Highlight and ensure we’re supporting them properly.

#### Where we store your personal data

Highlight operates from multiple, secure data centres within the European Economic Area ("EEA"). Your data may be processed by staff operating outside the EEA who work for us. By submitting your personal data, you’re agreeing to this transfer, storage or processing. Highlight will take all steps reasonably necessary to ensure that your data is treated securely and in accordance with the privacy policy described above. You should understand that keeping your password confidential is a key part of protecting your personal information, and you must not share your user login details, including your password, with anyone.

Unfortunately, the transmission of information via the internet is not completely secure. Although we will do our best to protect your personal data, we cannot guarantee the security of your data transmitted to the Service; any transmission is at your own risk. Once we have received your information, we will use strict procedures and security features to try to prevent unauthorised access.

#### Disclosure of your Information

We may disclose your personal information to any member of our company, or to contractors and third parties working for us. Where we disclose information to third parties or contractors, we will ensure that those people operate under the same confidentiality agreement, and respect the terms of the GDPR.

We may also disclose your personal information to third parties:

* In the event that we sell or buy any business or assets, in which case we may disclose your personal data to the seller or buyer of such business or assets.
* If Highlight or substantially all of its assets are acquired by a third party, in which case personal data held by it about its customers will be one of the transferred assets.
* If we are under a duty to disclose or share your personal data in order to comply with any legal obligation, or in order to enforce or apply our terms of use and other agreements; or to protect the rights, property, or safety of Highlight, our customers, or others. This includes exchanging information with other companies and organisations for the purposes of fraud protection and credit risk reduction.

#### Your Rights

**1. Opting Out**

You have the right to ask us not to use your personal data to tell you about new Highlight features and capabilities. You can use the ‘unusbscribe’ option at the bottom of these emails, for this purpose, or contact us using one of the methods below.

**2. Access to Information**

We want to ensure that the information we hold about you is accurate, and the GDPR gives you the right to access this information . You can see the account-level information we keep by using the ‘My Details’ option behind the user icon in the top right of your Highlight screen (after logging in). If you’d rather deal with us directly, or want more information, you can contact us through one of the routes below. Any access request may be subject to a fee of £10 to meet our costs in providing this information.

#### Changes to our Privacy Policy

Any changes we may make to our privacy policy in the future will be posted on this page and, where appropriate, notified to you by email.

#### Contacts

Questions, comments and requests regarding this privacy policy are welcomed and should be addressed to <gdpr@highlight.net>.

### User agreement

A user must agree to Highlight's terms and conditions to use the service.


# User Authentication

## Overview

This page details the processes for new users, account renewal and account expiry.

{% hint style="success" %}

#### Emails from Highlight

All emails will be sent from the **<noreply@highlight.net>** address
{% endhint %}

## New user

The new user process follows these steps:

1. New user is created by an Admin user, see [create user](https://support.highlight.net/help/admin/create_user) page
2. Admin user clicks **Save & Welcome** which sends an email to the new user. Also, a weekly scheduled report showing the top 10 heavily loaded watches will arrive in the new user's inbox each Sunday. Find out more about [scheduled reports](/reporting/network-reports/setup#scheduled-reports)

<figure><img src="/files/SXUNwsX4DJ3mhXKwxBJF" alt=""><figcaption></figcaption></figure>

New user clicks the **Set password** link in the email, creates new password and sets up [Multi-Factor Authentication](#multi-factor-authentication) (see next section).&#x20;

New user logs in for the first time, accepts our [terms and conditions](/getting-started/new-user/terms-and-conditions) and sees the **Let's get started** dialog&#x20;

<figure><picture><source srcset="/files/Gm8TbSpI9MY16y9lfXJu" media="(prefers-color-scheme: dark)"><img src="/files/Kzbs0FaQMdPvT0SahRxa" alt="Let&#x27;s get started modal"></picture><figcaption></figcaption></figure>

<figure><picture><source srcset="/files/S1jQ71PKRMX1VjqNb8Mj" media="(prefers-color-scheme: dark)"><img src="/files/lHAXa6siHLENSCyq2wRp" alt="Getting help modal"></picture><figcaption></figcaption></figure>

An **Account created** email is sent to the new user

<figure><img src="/files/0TiXBlLX4lad1HyM7EYw" alt=""><figcaption></figcaption></figure>

## Multi-Factor Authentication

Highlight's Multi-Factor Authentication (MFA) gives users a choice about their preferred secondary authentication method after username and password are entered. &#x20;

### Initial MFA set up

<figure><img src="/files/gRkdH0ENMVKEoihuztjK" alt=""><figcaption></figcaption></figure>

Users can link their Highlight account with an authenticator app like Microsoft Authenticator, Google Authenticator, 1Password, etc. The setup screens provide a QR code to do this or a manually entered key.  There's an additional option to verify via email. &#x20;

New users must enable MFA. Existing users can choose **Skip for now** for a period of time.  However, they will still be shown the MFA set-up screen at every login. &#x20;

### Subsequent logins&#x20;

<figure><img src="/files/8PeWMacZk1L5eA3rWFSN" alt=""><figcaption></figcaption></figure>

After setting up MFA, users will need to verify their account with a code at every login. &#x20;

## Federated Authentication for new users

Highlight supports multi-factor authentication and single sign-on through a process called **Federated Authentication** where password authentication is handed off to a third-party OAuth directory (typically Microsoft Azure AD).

There is the option to automatically create a new user in Highlight if that user has not previously logged in but has passed the authentication checks by the third-party provider. This is useful as new staff joining an organisation will be able to log into Highlight with no other admin intervention.

<figure><img src="/files/biJY0mObx4UG7uTYgSDU" alt="Edit Folder Authentication Tab - New users"><figcaption></figcaption></figure>

Auto-created users have the standard permissions (which include viewing heat tiles and details page, creating alerts and running reports). Extra admin permissions can be granted by other admin users if required.

Find out more about [how admin users can set up authentication](https://support.highlight.net/help/admin/create_tree#edit_a_folder_authentication_tab) and [contact us](/getting-started/contact-us) for assistance in setting up this feature.

## New user welcome process

When an Admin user clicks **Save & Welcome** the first **Welcome to Highlight** email is sent. The link to **Set password** expires 45 days from the date of the first welcome email. &#x20;

* If the user does not log in a week after the first email, a second welcome email is sent.
* If they do not log in after two weeks, a third welcme email is sent.&#x20;
* After 3 weeks, a final welcome email is sent.  See below for examples.

<figure><img src="/files/0V5WJbXU1k9kBSrPoPAW" alt=""><figcaption><p>If the new user does not log in, a further welcome email is sent after one week</p></figcaption></figure>

<figure><img src="/files/w5VJYj2r1jZ4gprQxKWK" alt=""><figcaption><p>If the new user still does not log in, a third further welcome email is sent after two weeks</p></figcaption></figure>

<figure><img src="/files/14ln4JowD18dDnz1IIDk" alt=""><figcaption></figcaption></figure>

If the new user does not log in after three weeks, a final welcome email is sent as shown above. &#x20;

If the user has not logged in within 45 days, their account is deleted.

An Admin user clicking **Save & Welcome** restarts the new user welcome process or (if 45 days have passed) the user will need to be recreated

## Account renewal

User accounts are set to expire after 3 months (for service providers) or 12 months (for customers). In order to renew a Highlight account, an existing user must confirm their email address. This can be initiated via the Home page or from an account renewal email which is automatically sent.

1. An existing user will see a message on the Home page for 14 days before their account is due to expire. They will also receive an email at 14 days and at 2 days prior to expiry (see steps 3 & 4)
2. The user clicks S**end renewal email** and the Home page message changes&#x20;
3. The user will receive an email like the one below
4. The user clicks the link in the email **(Renew your account now)** and the account is renewed

<figure><img src="/files/Lt47mlkmTxnc7guISCHF" alt=""><figcaption></figcaption></figure>

## Account expiry

1. When an account expires, the user will automatically receive a system email (see steps 4 & 5)
2. If a user attempts to log in to an expired account, the user sees a message **User account has expired**
3. After clicking the **Renew Account** link, the login screen shows **A renewal link email has been sent**

<figure><img src="/files/sI7HNVqcb8XPEKzpfLhI" alt="Account renewal screens"><figcaption></figcaption></figure>

1. The user will receive an email
2. Click the link in the email **(Renew your account now)** and the account is renewed

<figure><img src="/files/yYd9I2mvGVPELOKCEfFK" alt=""><figcaption></figcaption></figure>

If a user does not renew their account, Highlight will send the renewal email every 3 months, then an email at 11 months specifying the date the userid will be removed, and a final email 2 days before removal. Expired user accounts are automatically removed from Highlight after 12 months.

<figure><img src="/files/k6qzNK6BITU4DHwExQiE" alt=""><figcaption></figcaption></figure>

## Forgotten password

Users can request their own password reset, if needed:

<figure><img src="/files/oXKjTe5jgUJjTfzErxkM" alt="Forgot Password workflow"><figcaption></figcaption></figure>

The user will receive an email: &#x20;

<figure><img src="/files/zw3N6LrcwWHk7q0oHppH" alt=""><figcaption></figcaption></figure>

# Favourites

### Overview

Favourites are locations or folders that appear at the top of your Network Explorer tree for quick access. It's also possible to send alert emails on your favourites and run a report on your favourites.

### Using Favourites

On various pages in Highlight, an amber star appears to the right of any location or folder. This star has 3 possible options which are detailed below:

<table><thead><tr><th width="76.80078125">Icon</th><th>Text</th><th>Meaning</th><th>Action on Click</th></tr></thead><tbody><tr><td><picture><source srcset="/files/3ockiZ5RwmRzhIFDAwrA" media="(prefers-color-scheme: dark)"><img src="/files/FGpjvbVwjgAoSp2XqQId" alt="Add to favourites icon"></picture></td><td>Add to favourites</td><td>Selected item is not currently a favourite</td><td>Adds item to favourites and refreshes the tree</td></tr><tr><td><picture><source srcset="/files/Nw31Ctek93av8FvSWkWC" media="(prefers-color-scheme: dark)"><img src="/files/h6lSQXaytZH1f1BNjcgw" alt="Remove from favourites icon"></picture></td><td>Remove from favourites</td><td>Selected item is already a favourite</td><td>Removes item to favourites and refreshes the tree</td></tr><tr><td><picture><source srcset="/files/fySFd1SYlHknDYqsQQKi" media="(prefers-color-scheme: dark)"><img src="/files/0FpwhsCOeiT8q7TVIRN9" alt="Within favourites folder icon"></picture></td><td>Within favourite folder</td><td>Selected item has a parent folder already in favourites so it cannot be added or removed</td><td>No action</td></tr></tbody></table>

A location or folder cannot be added to Favourites if its parent folder is already in Favourites. If a parent folder is added to Favourites, any locations or subfolders within that folder are removed from Favourites since they cannot appear in Favourites twice.

When Favourites is selected in the Network Explorer tree, it's not possible to provide Reporting Audit log events.

### Alerting

Using Favourites, it's possible to alert on a customised set of folders and locations. First, select Favourites in the Network Explorer tree. Then, from Status Alerting, click , set up the alert and

{% hint style="info" %}
Alerts on favourites will be sent to your own email address as shown in your Highlight user account and cannot be changed.
{% endhint %}

### Reporting

Use Favourites to create a report on a customised set of folders and locations. First, select Favourites in the Network Explorer tree. Then, from Reporting Network, in **For:** choose Favourites instead of a folder.

It's also possible to set up a scheduled report on your favourites.

### Searching

# AppVis™

### Process Overview

For further details see [a description of AppVis in Highlight.](https://support.highlight.net/help/status/appvis)

Only Cisco devices are supported.

Here is an overview of the steps required to set up AppVis in Highlight:

1. Having Flow reporting capability is a pre-requisite. Follow the [process to enable Flow](https://support.highlight.net/help/getting_started/enable_flow)
2. (See warning below) [Configure each router](https://support.highlight.net/help/device_setup/flow#appvis) for the specific Flow template needed for AppVis
3. Install NBAR2 Protocol Pack on all devices involved in AppVis data collection\
   Note: NBAR2 is not a pre-requisite as AppVis can use NBAR standard classification, but NBAR has significantly fewer signatures than NBAR2. A signature is a classification of an application.
4. If using NBAR2 ensure that the router has an "advipservices" or "data" license otherwise the router will use standard NBAR classification even if a Protocol Pack is loaded. Licence details are available from [Reporting inventory](https://support.highlight.net/help/reporting/inventory#column_headers)
5. Contact your Service Provider to enable AppVis on a folder, and [set a folder](https://support.highlight.net/help/admin/create_tree#edit_a_folder) as the application domain
6. Edit the watch in Highlight to [add AppVis settings](https://support.highlight.net/help/admin/appvis) via the Edit Watch Autodiscovery and Applications tabs
7. Add [DSCP values to the CCD](https://support.highlight.net/help/admin/ccd#appvis_requirements) to provide AppVis analysis of QoS Classes
8. Give permission "Manage Applications" to nominated users so they can [Manage AppVis application groups](https://support.highlight.net/help/status/appvis#groups)

If results do not appear as expected, then follow our [AppVis Troubleshooting](https://support.highlight.net/help/troubleshoot/appvis) procedures.

&#x20;On the router, Flow and NBAR (which are required for AppVis) can cause high CPU load so every AppVis monitored device needs to be adequately powered for the volume of traffic expected.\
If you are planning to enable Flow/NBAR on a number of devices we suggest first selecting the busiest device for each model to check it can handle the additional CPU load.


# Flow

### Process Overview

For further details see [a description of Flow in Highlight.](https://support.highlight.net/help/details/flow)

Here is an overview of how to set up Flow in Highlight for the first time:

1. Check with your Service Provider that your contract allows for Flow, and that the network devices involved can run Flow analysis without causing CPU issues.
2. [Install an Agent server](https://support.highlight.net/help/device_setup/agent#server_location_and_provisioning) to be used as a Flow collector, and make note of the IP address.
3. Confirm there is network access from the routers to the collector without having the Flow packet address translated.
4. Allow UDP port 9996 from the routers to the Flow collector.
5. Allow TCP port 443 from the collector to your Highlight System.
6. Assign the collector to the Highlight folder structure using **Edit this Folder** then Agent selection.
7. [Configure each router](https://support.highlight.net/help/device_setup/flow) for Flow, using the IP address of the collector as Flow destination. Also specify the Flow packet source interface in the configuration, which is used by the router as source IP address of every Flow packet sent to the collector, and is configured in Highlight.
8. If each router does not have a Highlight entry, [create a new watch](https://support.highlight.net/help/admin/create_watch) in Highlight.
9. (See warning below) Edit the watch in Highlight to [add Flow](https://support.highlight.net/help/admin/flow) via the Edit Watch Applications tab, using the IP address of the configured Flow source interface.

If results do not appear as expected, then follow our [Flow Troubleshooting](https://support.highlight.net/help/troubleshoot/flow) procedures.

&#x20;Flow can cause a high CPU load on the router so the location needs to have a device which is adequately sized for the volume of traffic expected.\
If you are planning to enable Flow on a number of devices we suggest selecting the busiest device for each model to check it can handle the additional CPU load.

#### Special Cases

**WAN interface is encrypted or encapsulated, including MPLS**

If you want to analyse application traffic using the WAN interface but all traffic is either encrypted or encapsulated, adjust the normal process as follows:

* [Set up the router](https://support.highlight.net/help/device_setup/flow) LAN interface with the ip flow version 9 commands; but
* Select the WAN interface for the Highlight analysis when [adding flow](https://support.highlight.net/help/admin/flow) in the Edit Watch Applications tab


# Domains

### Overview

From its inception, Highlight was designed for multitenancy. Providers and consumers of managed IT services share information using a single pane of glass and collaborate secure in the knowledge that each user can only see the data they should see.

Highlight Domains builds on our multitenancy functionality by allowing consumers of IT services from more than one provider to see all their services with a single Highlight login and a simple switch between provider domains.

<figure><picture><source srcset="/files/ulEkqaWH5rqw4mdxwarL" media="(prefers-color-scheme: dark)"><img src="/files/EqEEcp0OZMi7JFBSc1H1" alt="Single login, multiple providers visible"></picture><figcaption></figcaption></figure>

### Domains - your multi-channel single pane of glass

<figure><picture><source srcset="/files/hV0obhgSmlAgsxrbDQH4" media="(prefers-color-scheme: dark)"><img src="/files/gsi13osFl4jQ3lgrPC0a" alt="Domains drop-down to switch between domains"></picture><figcaption></figcaption></figure>

Providers can choose whether consumers accessing their provider domain URL can switch to other domains or not. It is also possible for consumers to create their own domain to monitor services from providers who do not currently offer Highlight.

With domains you can login once via your own custom branded folder (for example, KFV Services) and use the drop-down in the top left to switch between your own services and those from other providers (CowCom and NTR in this example).

The **Account details** page lists the current domain and other accessible domains, including logo and URL(s).

<figure><picture><source srcset="/files/C2tYaqFnSI1RvUS3IZ3C" media="(prefers-color-scheme: dark)"><img src="/files/cce9lI2O74dRetLBFpZk" alt="My Account Details page "></picture><figcaption></figcaption></figure>

When viewing any individual service, the logo at the top of the page shows the provider. Clicking on this logo gives immediate access to the provider contact information.

<figure><picture><source srcset="/files/dOpx2FpDEnz6xTtj8bC3" media="(prefers-color-scheme: dark)"><img src="/files/EnIJCqjT6yw2HROBHTil" alt="Details page provider logo and contact info"></picture><figcaption></figcaption></figure>

Provider contact information can also be accessed from the **Domain contact details** in the user menu side bar, whilst the **About** panel shows Highlight contact details.

<figure><picture><source srcset="/files/YNtc8hsJSJrWxgpdoVpc" media="(prefers-color-scheme: dark)"><img src="/files/4VLdMfBdvoVEEo6Rhk5U" alt="Details page provider logo and contact info"></picture><figcaption></figcaption></figure>

Custom domain branding is also available on the login page and in user emails.

[Contact us](/getting-started/contact-us) if you'd like to start using domains.

### Domain branding

**Domain Branding Guide**

Highlight gives you an easy way to customise your domain to provide a fully branded portal to your staff and customers.

#### Customisable elements

\*User welcome emails, expiry emails and scheduled reports

#### What we need from you

**Login background image**

<br>

**Image guidelines:** Due to the responsive nature of the page that allows Highlight to look great on all screen sizes and the left hand side bar covering part of the image, we cannot control how much of the image will be displayed. We strongly suggest avoiding text entirely and keeping the most important parts of the image in the centre right.

**Logo**

We use the logo in both full and compact versions on light and dark backgrounds. The minimum we require is a single large logo (min 300 x 62px). If you wish to specify how the logo looks at compact size or on both dark and light then please do so. Vector based formats are best (.ai, .eps, svg) but we can accept any format. There is also space for an optional secondary logo, for use by a parent organisation, for example, which appears next to the small print in the bottom of the login page.

**Social media links**

By default the login screen displays links to Highlight social media pages. Currently these are not configurable but can be turned off completely.


# Network Explorer

### Overview

The Network Explorer panel, or Highlight "Tree", provides navigation to monitored services arranged into folders and locations and between Highlight systems if services are provided by more than one provider.

<figure><img src="/files/hjRUJoTyDCG52FNEG0Yo" alt="Network Explorer Tree"><figcaption><p>Network Explorer / Tree</p></figcaption></figure>

#### 1 - Highlight logo

The Highlight logo links to the user's Home page

<br>

#### 2 - Domains drop-down

Providers can choose whether consumers accessing their provider domain URL can switch to other domains or not. It is also possible for consumers to create their own domain to monitor services from providers who don't currently offer Highlight.

With domains you can use the drop-down to switch between your own services and those from other providers (CowCom and NTR in this example).

### Overview

<figure><picture><source srcset="/files/9aeM155P9GtGxFsAXtYL" media="(prefers-color-scheme: dark)"><img src="/files/OsYqBXrX8wP2wWUCqBYD" alt="Search dialog"></picture><figcaption><p>Use this dialog to search for folders, locations, watches and controllers</p></figcaption></figure>

### Search criteria

**Search term:**   enter a string of characters. Searches are not case-sensitive. For example, AB123 will find uukAB123 and xab123txy. The search term will be compared against the name and description (if available). You can also search on the device IP address, reference, product type and interface for watches.

{% hint style="info" %}
It's not possible to search on the description of a SD-WAN tunnel because it's auto-generated and dynamic.
{% endhint %}

**Go** button:  Click after entering your Search term or use the Return key. A blue bar appears under the search criteria showing the total items found. X deletes the term you've entered and any results.

**Network / Favourites** toggle

By default, the search is across your available *Network* or you can limit the search to your *Favourites.*

**Global / Folder and below** toggle

By default, the search is *Global* across the entire tree structure (regardless of which folder you've selected), or you can limit the search to the selected *Folder and below.*

### Search results

Results are returned alphabetically in the following sort order:

1. Folders
2. Locations
3. Watches are shown in alphabetical order with an identifying icon:
   1. Bearers and Wireless Controllers
   2. Dormant - for bearers with an interface marked as dormant
   3. Classes, VLANs and MLEs
   4. SD-WAN tunnels

Clicking on a folder or location from the results list will cause that folder/location to be selected in either the Network Explorer tree or in your Favourites.

Clicking on a watch (bearer, class, VLAN, MLE, WAP) will select the relevant location in the tree or favourites and open the Details page for this item.

Clicking on a controller will select the relevant location in the tree or favourites and open the location's Status Heat Tiles page.

{% hint style="warning" %}
**Limit:** if many results are found this view shows the first 500 items for the selected search term with a message **Showing the first 500 of ZZZ results**. You can reduce the result set by refining your search or navigating to a subfolder using Network Explorer and toggling to *Folder and below.*
{% endhint %}

Only users with permission to edit watches can check or uncheck the **Collect data** and **Show data** check boxes on a watch.

**Collect data:**  If unchecked, then the watch appears in *amber text* in the search results.

**Show data:**  If unchecked, then the watch does not appear in the search but may still be in Highlight. An [admin search](https://support.highlight.net/help/admin/browse#search) always shows the watch if it's in Highlight.


# IP Address Searching

Search for interface IP addresses

## Overview

Partner users can search for interface IP addresses on watches which may not be in Highlight.  Previously, interface IP addresses were only available following a tech test but not stored.  This feature will also find device IP addresses.&#x20;

{% hint style="warning" %}
Note: To enable this feature to work, MIB tables must not be locked down.&#x20;
{% endhint %}

Located in the user menu, select **IP Search** and enter an IPv4 address (IPv6 is not supported). In order to reduce the number of results, partial addresses and wildcards are not allowed. Use **X** to clear the search.

<figure><picture><source srcset="/files/1jS74zld0cigiAErY9d5" media="(prefers-color-scheme: dark)"><img src="/files/J8bajTHQ6qwmjnhKIvME" alt="IP Address Search "></picture><figcaption></figcaption></figure>

If a matching interface is found for the IP address entered, then all interfaces associated with that device are also returned, provided the interface has an IP address. The IP addresses which match the search are indicated by blue badges.

Data returned includes the following fields:

<table><thead><tr><th width="190">Column</th><th>Contents</th></tr></thead><tbody><tr><td><strong>Location</strong></td><td>This is the Highlight location containing the device with the matching IP address. This is a link so clicking it moves the tree to that location. Note: There may be more than one location for an IP address.  Results are sorted alphabetically by location name. </td></tr><tr><td><strong>Device Name</strong></td><td>If available, the name associated with a device.</td></tr><tr><td><strong>Device IP</strong> (address)</td><td>This is the device IP address.</td></tr><tr><td><strong>Interface</strong> (name)</td><td>This is the long interface name (IFDescr).</td></tr><tr><td><strong>Interface IP</strong> (address)</td><td>This is the interface IP address. </td></tr><tr><td><strong>Alias</strong></td><td>If available, the alias associated with the interface (IFAlias).</td></tr></tbody></table>

## Collapse/Expand

By default, the results are expanded to show all interfaces on a device. It's possible to collapse/expand the results to show only locations using the **- / +** to the left of the Location column. &#x20;

<figure><picture><source srcset="/files/AKAVHNikYng0vltQfy9T" media="(prefers-color-scheme: dark)"><img src="/files/FzrlEw5yvzd9u0iEhjHs" alt="IP Address Search collapsed and reverse sort order"></picture><figcaption></figcaption></figure>

Results are sorted alphabetically by location name. Reverse this by clicking on the header. The arrow indicates the sort order. &#x20;


# Release Notes

### Overview

Highlight is provided as a Software-as-a-Service solution and therefore is continually upgraded free of charge. We aim to release new versions every 1-2 months with interim maintenance releases as required.

Notification is given one week prior to an upgrade with detailed release notes showing all the enhancements and minor fixes in the build. The release notes will also contain links to additional information for major features. Once a new Highlight release has passed the QA testing phase it is available for partners and users to view, [contact us](/getting-started/contact-us) for login details.

If you would like to be notified of new releases please [contact us](/getting-started/contact-us).


# 26.9 - September 2026

DRAFT Release Notes 26.9 for September 2026

### Summary

In **26.9** we've added a performance test to ICMP Polling to show latency, packet loss and jitter. We've also added support for Extreme Networks switches.

### ICMP Polling: Add a test for latency, packet loss and jitter

For ICMP Polling, use a [CSV](https://help.highlight.net/getting-started/new-user/glossary#csvcomma_separated_values) file to upload IP addresses, with optional descriptions and locations. Highlight creates the locations and provides up/down status on the devices. You can alert and report on the availability of these devices.

In this release, you can optionally add a performance test to an ICMP Polling watch.  The parent ICMP watch shows up/down status on the Availability line.  The test shows additional metrics of latency, packet loss and jitter on a separate chart over time. Thresholds can be set for each metric with optional alerts sent if the threshold is breached. &#x20;

<figure><picture><source srcset="/files/utlqtoqO5phkRo9woKp8" media="(prefers-color-scheme: dark)"><img src="/files/m7Srrx6obqQkz5XLZiS7" alt="ICMP Polling Test "></picture><figcaption></figcaption></figure>

Find out more about [ICMP Polling](/admin/admin-page/controller#icmp-polling-main) and [performance tests](/details/details-pages/performance-charts#precision-delay-and-mos).&#x20;

### Extreme Networks: Switch support added

In addition to supporting Extreme Networks Wireless Access Points, switches can now be discovered and monitored via the Platform ONE API. &#x20;

Find out more about [Extreme Switches](/admin/admin-page/controller#extreme-networks-switches).&#x20;

### Bug fixes

* ICMP Polling: From the ICMP polling device dialog, there's now a link to the parent controller.

### Service description

# 26.6 - June 2026

Release Notes 26.6 for June 2026

### Summary

In **26.6** we've added the ability to poll via [ICMP](/getting-started/new-user/glossary#icmpinternet_control_message_protocol) and Multi-Factor Authentication for those logging into Highlight. &#x20;

### ICMP Polling - Beta

This functionality is useful on those occasions when [SNMP](/getting-started/new-user/glossary#snmpsimple_network_management_protocol) credentials are not available and straight-forward Ping only will suffice. Use a [CSV](/getting-started/new-user/glossary#csvcomma_separated_values) file to upload IP addresses, with optional descriptions and locations. Highlight creates the locations and provides up/down status on the devices. You can alert and report on the availability of these devices.&#x20;

Find out more about [ICMP Polling](/admin/admin-page/controller#create-edit-controller-icmp-polling).

### Multi-Factor Authentication

In addition to providing a username and password, users now need a secondary authentication method to log in.

Users can link their Highlight account with an authenticator app like Microsoft Authenticator, Google Authenticator, 1Password, etc. The setup screens provide a QR code to do this or a manually entered key.  There's an additional option to verify via email. &#x20;

Existing users can choose **Skip for now** for a period of time. New users must enable Multi-Factor Authentication (MFA).&#x20;

<figure><img src="/files/8PeWMacZk1L5eA3rWFSN" alt=""><figcaption></figcaption></figure>

In subsequent logins, users will need to verify their account with a code.&#x20;

Find out more about [MFA](/getting-started/new-user/user-authentication#multi-factor-authentication).

### Bug fixes

* SNMP Switches: Resolved a polling issue with HP switches, data now collected normally
* Scheduled Reports: Resolved a validation issue so these reports can now be saved
* Reporting Inventory: Vendor type fields have been updated

### Summary

In **26.4** we've added the ability to discover all ports on complex switches and set an agent on each Controller.&#x20;

### Complex switch port discovery - Beta

Highlight can now discover all ports on complex switches with indices such as 1/1/1. This is currently available in Beta for Cisco 92XX, 93XX and 95XX switches.  Other manufacturers and models are being tested before the change is expected to be widely available.

# 25.11 - November 2025

Release Notes 25.11 for November 2025

### Summary

In **25.11** we add the ability to alert when a controller is down.

### Alert when controller down

Be notified if your controller API integration fails.

<figure><picture><source srcset="/files/uWPehQFTUtuRjkfshy8V" media="(prefers-color-scheme: dark)"><img src="/files/INVIdINo2SxcbzHQST0b" alt="Controller Status chart"></picture><figcaption><p>Details page chart for Controller Status watch</p></figcaption></figure>

A parent controller may have hundreds of associated subwatches in the form of uplinks, tunnels, performance tests, etc. To limit alert spam, Highlight offers the option to suppress alerts on subwatches if the parent controller is uncontactable. Previously, this meant no alerts were sent if the controller was down. The controller status watch is designed to resolve this issue.

From 25.11, all new and existing controllers will have a controller status watch created automatically. Existing alerts configured as 'all watch types' will send stability alerts if the controller is down.  Alternatively, a specific alert for controllers only can be created - see image below. &#x20;

<figure><picture><source srcset="/files/iOpCP4elWRWJW3atjGOh" media="(prefers-color-scheme: dark)"><img src="/files/CO4kRStGe7mzyXQFQQSZ" alt="Alert on Controller down"></picture><figcaption><p>Type specific stability alert on Controllers</p></figcaption></figure>

# 24.13 - December-B 2024

Release Notes 24.13 for December -B 2024

### Summary

**24.13** is a release containing SD-WAN and AppVis enhancements.

### SD-WAN Enhancements

#### Cisco Meraki - Ready state now treated as Up

Highlight has been working with Cisco Meraki to better understand the scenarios under which an uplink service becomes unavailable or unresponsive, and the associated statuses we receive from Meraki for each scenario. Based on this, Highlight has made a change to our stability status logic to associate the state 'Ready' as a being an 'Up' state, where previously 'Ready' was treated as a 'Down' state with a red blip on the availability line.

#### Fortinet - Discovery logic updated for tunnels and performance tests

Highlight has enhanced the discovery logic of Fortinet SD-WAN networks to include some configuration elements of network topology. The result of this is a more comprehensive and reliable discovery of SD-WAN tunnels and their performance tests.

# Heat Tiles

### Overview

#### What are heat tiles?

Highlight’s heat tiles instantly show a clear status of both network and application services. They are more powerful than a simple traffic light or dashboard display because they show trends too. They are a time-based capability which understands that one incident does not make a network link bad, nor is it good the minute a long-standing problem is resolved.

Highlight uniquely measures performance using problem levels - an ongoing rating that smoothes the display and indicates if a situation is improving or deteriorating. There are 2 types of heat tiles detailed below.

Refer to [the Grid View page](/status/network/grid-view) for information on the grid.

***

#### Location tiles

Every location within your network is shown as an individual, summary tile with chevrons to indicate improving or deteriorating issues across stability, load and health metrics

<figure><picture><source srcset="/files/38ehVnNWhotlwYr9JmDB" media="(prefers-color-scheme: dark)"><img src="/files/9lGXpZqKW43vy6dnOAdB" alt=""></picture><figcaption></figcaption></figure>

#### Service tiles

Group watches from any location in your network into a single tile, custom-define thresholds to change tile colour based on the total number of issues

<figure><picture><source srcset="/files/AokgdzJdyxcckdYeDy5o" media="(prefers-color-scheme: dark)"><img src="/files/8Z89ApTP6E1oLjSbPw16" alt=""></picture><figcaption></figcaption></figure>

***

### Service tiles

These tiles are created by adding watches to a container and setting it to display as a tile.

<figure><picture><source srcset="/files/LrntAqB3iUv0NfKKqXds" media="(prefers-color-scheme: dark)"><img src="/files/Zw7g5o16RjAe5Ia367MT" alt=""></picture><figcaption></figcaption></figure>

#### Service Tile Example

A service tile for email could comprise the summary status of:

* &#x20; TCP tests from the local router to the server listening ports (application status)
* &#x20; Link Health watches for the Internet service
* &#x20; WAN tests from remote locations to the Data Centre (to assess the impact of the network)

### Location tiles - React to issues: Any or All

**Watch-centric   (React to issues: ANY)**

With this default setting, Highlight's location tiles change colour based on the worst case of any single watch in the location. This view enables service provider operations teams to quickly see locations with issues to be resolved but can occasionally result in a sea of red tiles for relatively minor issues.

With **Any** selected on the "React to issues" toggle, location tiles are:

**Green** - no issues

**Amber** - some watches are in a transitional (amber) state

**Red** - some watches are in a degraded (red) state

**Location-centric   (React to issues: ALL)**

Highlight provides an alternative view which is based on the location as a whole, rather than on any single watch. In this view an amber tile indicates a location with degraded connectivity which is still online. This view is beneficial to enterprises and service providers wanting a higher-level overview of the entire network.

With **All** selected on the "React to issues" toggle, location tiles are:

**Green** - no issues

**Amber** - some watches have issues and some are green, or all watches are amber

**Red** - all watches have issues with at least one red

# Highlight Alerting Mechanism

### Highlight Alerting Mechanism

The mechanism works on the principle that if an error condition is encountered in any element then a fuel gauge-type counter is decreased. In all other circumstances, it’s increased. When the counter goes below pre-set thresholds, Highlight signals an amber condition, and then a red. Please see below the conditions when the various counters are decreased, associated with Stability, Load, or Health which we refer to as level 3 metrics.

{% hint style="info" %}

#### Custom defined  or configurable settings

Some thresholds are hard coded in Highlight and Admin users can define others. Targets in performance tests are defined during setup. These are labelled as "configurable" below.
{% endhint %}

How quickly a heat tile changes colour is governed by the sensitivity settings. Please find out more about [changing the sensitivity of heat tiles](https://support.highlight.net/help/admin/heat_tiles_sensitivity) or [contact us](/getting-started/contact-us) for details.

{% hint style="info" %}

#### In maintenance  <picture><source srcset="/files/DCPpkgHz04jexgzIfnFF" media="(prefers-color-scheme: dark)"><img src="/files/JrKVRD5I67SN056HBH2v" alt="Maintenance indicator"></picture>

Watches in maintenance do not send alerts, change the colour of heat tiles nor decrement availability figures
{% endhint %}

{% hint style="info" %}

#### Dormant  <picture><source srcset="/files/5SBR5jHWLjG8EvtTvowp" media="(prefers-color-scheme: dark)"><img src="/files/vFD1plJG5q4H74nKqNNV" alt="Dormant icon" data-size="original"></picture>

Dormant interfaces are not expected to pass traffic and only send stability alerts if the device is uncontactable
{% endhint %}

#### Stability

Decrease the counter if any of the following conditions are met, which we refer to as level 2 metrics affecting stability:

* The device loses connection with either of the Highlight pollers
* The monitored interface is down or indicating a brief outage or has been taken out of service or no longer exists
* There has been a device restart
* &#x20;A switch port designated as critical is down
* &#x20;**Performance tests: ICMP Ping, UDP Echo and TCP Open:** 100% packet loss of all tests in a sample
* **Performance test: MOS:** Application failure, MOS is less than 1.0
* **Performance test: Precision Delay:** 100% packet loss of all tests in a sample. The health index is also affected.

#### Load

Decrease the counter if any of these conditions are met, which we refer to as level 2 metrics affecting load:

* Link utilisation (traffic in or out) exceeds threshold (default is 80%  - configurable)
* Tunnel utilisation (traffic in or out) exceeds threshold (default is 82% )
* Traffic in or out on a dormant watch exceeds a threshold (default is 1000 Kbps - configurable)
* CPU for a router exceeds 60%
* WiFi Client Count exceeds a threshold (default is 30 client devices - configurable)
* Wireless Utilisation exceeds a threshold (default is 50% - configurable)

#### Health

Decrease the counter if any of these conditions are met, which we refer to as level 2 metrics affecting health:

* Link errors exceed a threshold (default is 1% or 10,000 packets per million - configurable)
* Link congestion occurs:
  * Queue length exceeds 0
  * Discards exceed a threshold (default is 1% or 10,000 packets per million - configurable)
  * Class drops exceed 0 (configurable)
* **Broadband Clarity:**
  * The connection speed of the broadband service drops below the speed threshold, which is auto-learned or manually set - configurable
* &#x20; **Cellular Clarity:**
  * The signal strength score of the cellular service drops below the threshold, which may be set (default is 0 - configurable)
* &#x20;**WiFi:**
  * Congestion (discards) exceeds a threshold (default is 1% or 10,000 packets per million - configurable) or
  * Signal Problems exceed a threshold (default is 25% - configurable)
* &#x20;**Performance tests - ICMP Ping, UDP Echo and TCP Open:**

  * Any one of the tests in a sample shows response exceeds the target (configurable)
  * At least one test in a sample fails to respond (lost packet)

  Note: One sample can contain up to six test results; if all tests in a sample fail it affects stability and health
* **Performance tests - Precision Delay and MOS:** (configurable)

  <table><thead><tr><th width="402">Condition</th><th>Precision Delay</th><th>MOS</th></tr></thead><tbody><tr><td>Average response from the burst exceeds response target</td><td>Yes</td><td>Yes</td></tr><tr><td>Percentage of lost packets exceeds packet loss target</td><td>Yes</td><td>Yes</td></tr><tr><td>Jitter measured over the burst exceeds jitter target</td><td>Yes</td><td>Yes</td></tr><tr><td>MOS Score is less than target</td><td>N/A</td><td>Yes</td></tr></tbody></table>

  #### Alert generation

  Note that each level 2 metric above can trigger an alert so for example you may get an alert when a heat tile goes red caused by Inbound Link utilisation, then another alert caused by Outbound Link utilisation even though the tile is already red. The tile colour represents the worst case of all level 2 metrics associated with it.


# Grid View

### Overview

Available for locations only, see your services in a grid with underlay, overlay and LAN services in their own section.  Refer to [the Heat Tiles page](/status/network/heat-tiles) for information on location tiles.

#### Columns

Columns in the grid are services which might be available on a typical network and divided as shown below. If **Hide empty columns** is checked, only columns with watches are shown.

**UNDERLAY**

**Ethernet:** dedicated access bearers and any performance tests on the bearers

**Broadband:** ADSL and SDSL bearers (which do not have a switch subwatch)

**Cellular:** SNMP bearers with [Cellular Clarity](/details/details-pages/cellular-clarity) enabled or SD-WAN cellular uplinks

**OVERLAY**

**Class:** all Classes of Service and any performance tests on the classes

**VLAN:** VLANs and any performance tests on the VLAN

**Uplinks:** SD-WAN uplinks and any associated performance tests, see [SD-WAN Uplinks in the Grid](#sd-wan-uplinks-in-the-grid) section below

**TUNNELS**

**Tunnels:** SD-WAN tunnels and any associated performance tests, see [SD-WAN Tunnels in the Grid](#sd-wan-tunnels-in-the-grid) section below

**LAN**

**Controller Status:** Controller status watches show the state of the controller itself

**Perf Agents:** Performance agents and any associated performance tests

**Switch:** all switch parent bearers and switch watches

**WiFi:** all Wireless Access Points

**IoT:** all cameras and sensors

**APP TESTS**

**App Test:** containers with "Show as App Test column" enabled on the [Grid tab](https://support.highlight.net/help/admin/create_container#grid_tab), container description (if available, otherwise container name) is shown as the column header, see [App Tests in the Grid](#app-tests-in-the-grid) section below

#### Cells

<figure><picture><source srcset="/files/gF1frxVmTUpV2Kcm3dWb" media="(prefers-color-scheme: dark)"><img src="/files/RcnWvhzATUbpSSubDIQ9" alt="Illustration of grid cells in various states"></picture><figcaption></figcaption></figure>

Cells may be one of 4 colours to indicate if watches of that type exist in the location or folder:

**Grey:** no watches

**Green:** watches exist and none have issues

**Amber**/**Red:** watches exist and some have issues

If there are watches with issues, the colour of the cell is determined by the [Any/All toggle](#react-to-issues-any-or-all), see section below.

<figure><picture><source srcset="/files/nHcw5G5QnWvRP0SGNLHO" media="(prefers-color-scheme: dark)"><img src="/files/R2BQEjfeabx4OxYE2PK2" alt="Stability, Load and Health filters"></picture><figcaption></figcaption></figure>

Cells with issues show the type of issues: stability, load, health or some combination of these and the duration of the most recent issue shown as:

**Now:** for under 1 hour or

**h:** for hours, from "1h" up to "47h" or

**d:** for days, from "2d" up to ">30d"

***

#### Column headers

The column header shows the number of cells with issues in a column. Hover on the header to see the total cells. This is not available when **Group by folder** is selected.

***

#### Sorting

By default, the grid is sorted in alphanumeric order according to the first column, Folder/Location, and is not case sensitive.

<div><figure><picture><source srcset="/files/WrnBSrSgtqu0E36avAzB" media="(prefers-color-scheme: dark)"><img src="/files/ENBwarHX6iNakQ5AVfmB" alt="Column header with cells sorted in descending order"></picture><figcaption></figcaption></figure> <figure><picture><source srcset="/files/XvbWRDDCaOXUpHAhW1KH" media="(prefers-color-scheme: dark)"><img src="/files/eOffGODtRASwXnFt6IRi" alt="Column header with cells sorted in ascending order"></picture><figcaption></figcaption></figure></div>

Click on a column header to sort by that column or reverse the order;\
A vertical arrow indicates which column the grid is sorted on

Cells in a column are sorted by issue duration and then by Folder/Location if all other details match.

### Row colours displayed

<figure><picture><source srcset="/files/rPaTeHTP4PtNsgoZvpIG" media="(prefers-color-scheme: dark)"><img src="/files/NeYVXW06qPyjvE7e6nov" alt="Red, Amber and Green filters options"></picture><figcaption></figcaption></figure>

A count of rows in each state (red/amber/green) is displayed in the panel header at all times and adapts to the Any/All and Group by folder settings.\
Click on each colour to hide or show those rows in the display.

The "Reset all filters" button returns colour settings to their default&#x20;

The display resets to show all colours each time you log in.

### React to issues: Any or All

**Watch-centric (React to issues: Any)**

With this default setting, cells and rows in the grid view change colour based on the worst case of any single watch in the category or location. This view enables service provider operations teams to quickly see areas with issues to be resolved but can occasionally result in a sea of red cells and rows for relatively minor issues.

With **Any** selected on the "React to issues" toggle, cells and rows are:

**Grey:** For cells only, no watches in this category in this row

**Green:** No issues

**Amber:** Some watches are in a transitional (amber) state

**Red:** Some watches are in a degraded (red) state

**Location-centric (React to issues: All)**

Highlight provides an alternative view which is based on the location (or folder) as a whole, rather than on any single watch. In this view an amber row indicates a location with degraded connectivity which is still online. This view is beneficial to enterprises and service providers wanting a higher-level overview of the entire network.

With **All** selected on the "React to issues" toggle, cells and rows are:

**Grey:** For cells only, no watches in this category in this row

**Green:** No issues

**Amber:** Some watches have issues and some are green, or all watches are amber

**Red:** All watches have issues with at least one red

<figure><picture><source srcset="/files/m590bfgeQkmgpNLlc7Vh" media="(prefers-color-scheme: dark)"><img src="/files/O7LvC0Yk1zxDZt7b1sHV" alt="React to issues toggle"></picture><figcaption></figcaption></figure>

The setting of Any or All is remembered when you next log in

The count of rows in each state (red/amber/green) adapts to the Any/All setting

### SD-WAN Uplinks in the Grid

SD-WAN uplinks and any associated performance tests are shown in the Uplinks column with the following exceptions:

* Cellular - if the uplink has a cellular child watch, or Meraki call the interface 'cellular', it is shown in the Cellular column in the Underlay section
* Site Link Broadband - if the uplink has "site link" enabled AND the bandwidth up and down values differ, it is shown in the Broadband column in the Underlay section
* Site Link Ethernet - if the uplink has "site link" enabled AND the bandwidth up and down values match, it is shown in the Ethernet column in the Underlay section

Find out more about [site links](https://support.highlight.net/help/reporting/site_availability).

### SD-WAN Tunnels in the Grid

<figure><picture><source srcset="/files/elRmpLFX5oYKEbjnWCID" media="(prefers-color-scheme: dark)"><img src="/files/MF0RTwsKo6HphQ0zrLXd" alt="Tunnels in the Grid"></picture><figcaption></figcaption></figure>

Performance tests are shown in the Grid column with their parent tunnel.

If the selected folder in the tree is a customer folder and contains SD-WAN tunnels, then Highlight expands the single Tunnel column to show all destination locations. The same applies to locations if their parent folder is set to customer visibility.

At a glance, you can quickly see

### App Tests in the Grid

<figure><picture><source srcset="/files/kqyhuS56xoVHgOQs33z5" media="(prefers-color-scheme: dark)"><img src="/files/wjCQhKgColFrwrSgHAoS" alt="App Tests in the Grid"></picture><figcaption></figcaption></figure>

If the selected folder in the tree is a customer folder and includes a container with **Show as App Test column** enabled, then Highlight shows the container as a column in the Grid.

If the selected folder in the tree is an internal folder and includes one or more containers with **Show as App Test column** enabled, then Highlight shows a single aggregated column called "App Test" in the Grid.

* Only the status of performance tests is included even if the container includes other watch types.
* Performance test are duplicated in the Grid appearing both in the Underlay or Tunnel section and in the App Tests section if included.

Name/Description toggle

All watches have a name and a description is optional. If no description is configured, the watch name shows regardless of the status of this toggle. The option of Name or Description is remembered when you next login.

#### Sort

<figure><picture><source srcset="/files/YilFqVzNEppyIdBZYKgM" media="(prefers-color-scheme: dark)"><img src="/files/uNawXqWWrTWRbF5epN8D" alt="Dropdown menu for changing sort options"></picture><figcaption></figcaption></figure>

There are 3 options available for sorting: A - Z, Issues or Type. The selection is remembered when you next login.

**A - Z**

Watches are sorted by alphabetically by description

**Issues**

Sorting by issues puts the most recent amber and red watches at the top followed by green watches, which are sorted by description

**Type**

This sorts the list by watch type and then by description

Order for Services:

1. Controller Status
2. Bearers
3. Tunnels
4. Classes
5. VLANs
6. MLEs

# WiFi

### Overview

WiFi monitoring is fully integrated with all aspects of Highlight. This page explains our WiFi metrics then how they are used to colour heat tiles and generate alerts; how they are graphed on the Details page and how they feed into Reporting.

<figure><picture><source srcset="/files/NY26wc9btnwTBKOw5tEt" media="(prefers-color-scheme: dark)"><img src="/files/RrhWyUbD9h7HJM7O1DuU" alt="Graphic demonstrating Wifi support in a network with Highlight observability"></picture><figcaption></figcaption></figure>

### WiFi Metrics

Every five minutes Highlight collects the information below if available from the vendor. Refer to this [grid showing which WiFi features are provided by each supported vendor](/details/wifi/wifi-by-vendors) for specific details.

<table><thead><tr><th width="96">Affects</th><th width="117">Information</th><th>Details</th></tr></thead><tbody><tr><td><picture><source srcset="/files/OZ3DTNisbdqBsAW6WILb" media="(prefers-color-scheme: dark)"><img src="/files/RORmnpxg2UCwiCqzZEMU" alt="Load icon"></picture></td><td>AP Traffic In/Out</td><td>Total volume of Wireless traffic flowing in and out of the Access Point (AP)</td></tr><tr><td><picture><source srcset="/files/OZ3DTNisbdqBsAW6WILb" media="(prefers-color-scheme: dark)"><img src="/files/RORmnpxg2UCwiCqzZEMU" alt="Load icon"></picture></td><td>AP Utilisation</td><td>The percentage utilisation of the two radio channels, 2.4GHz and 5GHz, on that AP</td></tr><tr><td><picture><source srcset="/files/n3aKwpo8PEZIQcGw5b5m" media="(prefers-color-scheme: dark)"><img src="/files/PoxvRaayjuuyfApWZQeA" alt="Stability icon"></picture></td><td>AP Status</td><td>Whether a AP is up or down. This considers (a) connectivity to the AP is up and running, and (b) each radio on the AP is up and working. If any of these report down from an operational perspective, Highlight reports a problem with the AP. 'Administrative' down status (where the AP or an interface has been deliberately shut down by the administrator) will not show as an outage or trigger an alert. Highlight also detects reboots of the AP and shows them as events / blips.</td></tr><tr><td><picture><source srcset="/files/OZ3DTNisbdqBsAW6WILb" media="(prefers-color-scheme: dark)"><img src="/files/RORmnpxg2UCwiCqzZEMU" alt="Load icon"></picture></td><td>Client Count</td><td>The number of client devices connected to the AP</td></tr><tr><td><picture><source srcset="/files/sekHJSUEdVDIewUtucNW" media="(prefers-color-scheme: dark)"><img src="/files/LyMUj3brHOURcB1Mr9dR" alt="Health icon"></picture></td><td>Congestion</td><td>Highlight derives a metric to indicate congestion level on the AP radio networks. For consistency with other types of link, the metric used is the percentage of send attempts that require retransmissions. Since a certain level of retries is entirely normal, Highlight looks for retry levels above a certain threshold which Admin users can configure to avoid spurious alerts. Congestion is not calculated unless traffic volumes are more than 1 frame per second.</td></tr><tr><td><picture><source srcset="/files/sekHJSUEdVDIewUtucNW" media="(prefers-color-scheme: dark)"><img src="/files/LyMUj3brHOURcB1Mr9dR" alt="Health icon"></picture></td><td>Signal Problems</td><td>Highlight gives an indicative picture of how well clients are connecting by monitoring the percentage of connected client devices which are reporting poor signal strength (poor signal means SNR (Signal-to-Noise Ratio) of 1 or 2 bars (under 20 decibels).</td></tr><tr><td><picture><source srcset="/files/OZ3DTNisbdqBsAW6WILb" media="(prefers-color-scheme: dark)"><img src="/files/RORmnpxg2UCwiCqzZEMU" alt="Load icon"></picture></td><td>AP CPU Load</td><td>The CPU Utilisation / Load on that AP, as a percentage</td></tr></tbody></table>

Then Highlight:

* Makes all the above information available through the Details page for individual APs, drawing graphics for traffic load (utilisation), client device count, CPU utilisation, signal, congestion and availability (on the Access Point Health chart)
* Feeds this information through the alerting engine to generate alerts when any metric goes outside the prescribed limits (which can be set at a folder or location level)
* Shows the status of APs via heat tiles on the Status Heat Tiles page (Access Points will show under location tiles and can be associated to service tiles also)
* Shows this information in strip charts on the Reporting pages
* Summarises this information in Reporting

### Details page

### Reporting

**Static Information**

Highlight periodically refreshes the list of APs. Descriptive information (configured into the AP by the Wireless LAN administrator) is collected by Highlight for each AP on discovery and then updated periodically:

| Information         | Example            |
| ------------------- | ------------------ |
| WAP Name            | Sales001           |
| WAP Location        | Southampton        |
| Serial Number       | ESP-WCL5502-384736 |
| WAP Type            | Cisco-WLC5503      |
| SSIDs set on the AP | BYOD, Guest-AA     |

This information is used to title the Details page for individual APs and is available in the Reporting area, enabling users to list all their APs with serial numbers, locations etc.

**Summarised / Reporting information**

Highlight provides WiFi summary reporting. A number of WiFi specific columns are available for inclusion in reports and graphics can be included with these:

| Information                       | Details                                                                                                                                                                                                                       |
| --------------------------------- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| Number of Clients : Peak, Average | The Peak and Average number of connected clients for the selected period (day, week or month).                                                                                                                                |
| Radio Utilisation : Peak, Average | Peak and Average utilisation of the two radio networks. Use this as an indicator of how busy, overall, the shared radio channels are. As utilisation grows, you will start to see congestion.                                 |
| Volume                            | Volume of traffic in and out of the AP. Use this to see how traffic volumes are changing on individual APs, and across your wireless network. You'll be able to graph this to see trends.                                     |
| Congestion                        | Level of congestion as percentage retries. List this across the WiFi network to see areas where usage is getting too high                                                                                                     |
| Signal Problems                   | The percentage of client connections suffering from a poor quality signal. There is no relationship to the threshold in this column, see exceptions instead. List this metric across the radio network to find trouble spots. |

[An explanation of the fields available for WiFi reporting ](/reporting/network-reports/output#description-of-fields-in-highlight-reports-n-z)is available. In addition, there's the usual metrics for a link such as Outages, Availability, Exceptions, Issues Scores.&#x20;

### Device Support

The following wireless devices are supported:

* Extreme (formerly Aerohive)
* Aruba AirWave
* Aruba Instant On
* Cisco
* Meraki
* Ruckus SmartZone
* Ubiquiti UniFi

Other vendors may be added as demand and requirements emerge, taking into account feedback from users and results of more technical research.

Each manufacturer provides different metrics for monitoring WiFi performance. The fields are blank or show "not returned" when the device does not provide a metric. Refer to this [grid showing which WiFi features are provided by each supported vendor](/details/wifi/wifi-by-vendors) for more details.


# Hybrid WAN

### Overview

In order to improve efficiency, some networks are now set up to share traffic across two or three separate services based on application, load and other factors. The options might be a private, more expensive MPLS link and the public internet but they could also be any links. In this network configuration, smart routers continually analyse the available paths and route traffic based on the more cost effective option. Highlight's Hybrid WAN feature gives you visibility of which route is being used.

<figure><picture><source srcset="/files/szoCi7DSdET5k4qfHvdm" media="(prefers-color-scheme: dark)"><img src="/files/39O9ENmm7JvME8PLo8oK" alt="Graphic demonstrating Hybrid WAN in a network with Highlight observability"></picture><figcaption></figcaption></figure>

When clicking a location tile with two or three Hybrid WAN links, a bar showing the split of traffic on the routes for the last 30 minutes appears in the watch status panel for the location. The description for each bearer is shown or alternatively the watch name is shown. Hybrid WAN links are shown in alphabetical order by **description** (if available) so Primary, Secondary and Tertiary circuits show in order with consistent colours.

1. Primary (pink)
2. Secondary (soft purple)
3. Tertiary (teal)

# Alerting


# Alert Management

### Overview

### Highlight's Alerting Mechanism

<figure><picture><source srcset="/files/GkPuFKMHMNkA8RuixbbV" media="(prefers-color-scheme: dark)"><img src="/files/FfC0KTjhKmiZrEgG7OXN" alt="Service tiles"></picture><figcaption></figcaption></figure>

Highlight's heat tiles are more powerful than a simple traffic light or dashboard display because they show trends too. They are a time-based capability which understands that one incident does not make a network link bad, nor is it good the minute a long-standing problem is resolved.

Highlight uniquely measures performance using problem levels - an on-going rating that smoothes the display and indicates if a situation is improving or deteriorating.

#### Alert generation

Alerts are generated by individual metrics such as Inbound Link utilisation and Outbound Link utilisation crossing thresholds, and not specifically the tile changing colour. The tile colour represents the worst case of all metrics associated with it.\
For example you may get an alert when a heat tile goes red caused by Inbound Link utilisation, then another alert caused by Outbound Link utilisation even though the tile is already red.

Read more about [Highlight's Alerting Mechanism](/status/network/highlight-alerting-mechanism) for a list of metrics affecting Stability, Load, and Health; and [Highlight's Alert Messages](/status/alerting/alert-messages).

{% hint style="info" %}
**Permission needed:** None, to create an alert. This is a built-in feature of Highlight although those with **Manage folders/locations** and **Edit watches** can alter how the alerting mechanism works.
{% endhint %}

### 1. Alerting thresholds

<figure><picture><source srcset="/files/JOZFeJjYJppzcOloTyck" media="(prefers-color-scheme: dark)"><img src="/files/ZBZjnCSo37JmremcYt02" alt="Alerting thresholds bearers"></picture><figcaption></figcaption></figure>

Admin users can customise the thresholds which Highlight uses to generate alert emails (if set up) and change the colour of heat tiles. Thresholds can be defined on WiFi, bearers and classes for each folder.

Read more about [alerting thresholds](https://support.highlight.net/help/admin/alerting_thresholds) and [how these impact the alerting mechanism.](/status/network/highlight-alerting-mechanism)

{% hint style="info" %}
&#x20;**Permission needed:** Manage folders/locations
{% endhint %}

### 2. Alerting sensitivity

<figure><picture><source srcset="/files/GmPHc4NVlBtmfxfli8Hw" media="(prefers-color-scheme: dark)"><img src="/files/YTQyvHRSF81FCkeSaj9a" alt="Sensitivity settings"></picture><figcaption></figcaption></figure>

Admin users can modify the rate at which the heat tiles change colour and therefore, generate alerts. Settings can be changed to react quickly or slowly.

Read more about [alerting sensitivity.](https://support.highlight.net/help/admin/heat_tiles_sensitivity)

{% hint style="info" %}
**Permission needed:** Manage folders/locations
{% endhint %}

### 3. Custom targets

Performance tests have custom-set targets, as shown by the horizontal blue line in the image below. Admin users can edit these as needed.

Read more about [performance test custom targets.](https://support.highlight.net/help/admin/create_performance_test)

{% hint style="info" %}
&#x20;**Permission needed:** Edit watches
{% endhint %}

### 4. Alerting controlled by users

<figure><picture><source srcset="/files/JfC0ztD8fiD82rcJ9dxX" media="(prefers-color-scheme: dark)"><img src="/files/PeMLeRH8Z6MdwhFhTtXo" alt="Create Alerting with Default settings"></picture><figcaption></figcaption></figure>

Any user can create their own alerts. The user decides:

* which issues to be notified about (amber or red)
* when to be notified (when issues starts, clears or both)
* which alert period to use (any time of day, or business hours which refers to the local timezone for the location)
* whether they want to know about stability, health, load, or any combination of the three

An amber alert for "issue starts" is sent on green-amber transition only; an amber clear is sent on amber-green transition\

### 5. Suppressing alerts on bearers

<figure><picture><source srcset="/files/C0JKtFUybjLZv9gBJDu0" media="(prefers-color-scheme: dark)"><img src="/files/zaXeeeyskH6PiWAfjCd2" alt="Edit Watch Site Link Alerting Disabled"></picture><figcaption></figcaption></figure>

<figure><picture><source srcset="/files/7GGoc4rvwCoLvjRK6hxG" media="(prefers-color-scheme: dark)"><img src="/files/KUAbIkjY9GjRC9Y2pI4p" alt="Edit Watch Site Link Alerting Disabled"></picture><figcaption></figcaption></figure>

It is possible to disable alerts:

1. &#x20;**Send alerts** - on that bearer watch, and all its discovered elements and performance tests, by unchecking the **Send alerts** check box
2. &#x20;**Site link** - for other bearers at the same location and all associated watches (performance tests, VLANs, classes, etc.)

#### 1. Disable alerting on the bearer

This stops the watch, plus all its discovered elements and performance tests, contributing to alerts. Samples will affect heat tiles when thresholds are crossed, but no alerts of any kind will be generated.

Read more about [editing a watch to disable alerting.](https://support.highlight.net/help/admin/edit_watch#main_tab)

#### 2. Disable alerting for other bearers at the location and associated watches

Whether a location has one or many links, this Admin capability means secondary, spurious alerts are not generated when the primary links are down. Alerts for a location are suppressed when main bearers are each marked as a Site link and all Site link bearers at the location are alerting for stability.

Read more about [alert suppression from bearers using Site link.](/status/alerting/alert-suppression-using-site-links)

{% hint style="info" %}
&#x20;**Permission needed:** Edit watches
{% endhint %}

### 6. Disabling an alert for selected watch types

<figure><picture><source srcset="/files/Oi8EvYmqQ7lcFeJePsaK" media="(prefers-color-scheme: dark)"><img src="/files/LsDxobnJHiaFrfKZfbGF" alt="Alert on watch type"></picture><figcaption></figcaption></figure>

By default an alert covers an issue with all watch types (e.g. bearer, performance test etc). You can decide when the alert is created or edited whether or not it covers particular watch types. In the example here, the alert will only be sent for stability issues with Wireless Access Points.

Read more about [alerts on watch type](/status/alerting/alerting-email#create-alerts).

{% hint style="info" %}
**Permission needed:** None (works for any users except those with the View Heat Tiles Only permission)
{% endhint %}

### 7. Disabling alerts on subfolders

You can decide whether or not to include all subfolders with an alert. In the example here, two subfolders (Datacentre and AsiaPac) have this alert suppressed. This means no alerts will be sent for issues related to alert ID 55322 for any watches in these two subfolders.

Read more about [disabling alerts on subfolders](/status/alerting/alerting-email#inherited-alerts).

&#x20;Suppression is available at the folder level not at the location level.

{% hint style="info" %}
**Permission needed:** None (works for any users except those with the View Heat Tiles Only permission)
{% endhint %}

### 8. Maintenance windows

Watches in maintenance do not send alerts, change the colour of heat tiles nor decrement availability figures.

Highlight tracks all issues during a maintenance window. If a watch goes down during a maintenance window and hasn’t come up by the time the maintenance window finishes, Highlight will then send an alert for that watch.\
Similarly if a watch is in amber state before maintenance but is in red state after, Highlight will send any enabled red alerts.

Read more about [scheduling maintenance using a container](https://support.highlight.net/help/admin/create_container)[, maintenance indicators on the Status page](/status/network/maintenance-indicators), and [maintenance indicators on the Details page](/details/details-page-options/maintenance-indicators#overview)

{% hint style="info" %}
**Permission needed:** Manage maintenance
{% endhint %}

### 9. Suppressing alerts on WiFi APs

By default, if Highlight cannot contact the wireless controller then blue blips show on the Availability line of the [Access Point chart](/details/wifi/ap-access-point) and alerts are sent for each AP associated with the controller. To stop the alerts, check the **Alerting** box on the [Edit controller dialog](https://support.highlight.net/help/admin/create_controller#main_tab_controller_details).

{% hint style="info" %}
**Permission needed:** Edit watches
{% endhint %}

### 10. Suppressing alerts when controller uncontactable

<figure><img src="/files/Iacydhp5i4t4IOgekaKw" alt="Edit Controller dialog showing Alerting checkbox"><figcaption></figcaption></figure>

By default, if Highlight cannot contact the parent controller then blue blips show on the Availability line of the watches associated with the controller and, if configured, stability alerts are sent for each associated watch. To stop the alerts, check the **Alerting** box on the [Edit controller dialog](https://support.highlight.net/help/admin/sdwan_controllers#create_edit_controller_common_settings).

Use this setting with the [Controller Status watch](https://support.ci.highlight.net/help/admin/sdwan_items#edit_controller_status_main_tab) to receive a single stability alert when the controller is down.

### Problem text in Alerts

Highlight alerts contain a Problem field which identifies which aspect of Highlight has triggered the alert.

This section contains the problem messages, and what part of Highlight triggered the alert (the "level 2" metric), and whether Stability, Load or Health is affected on the heat tile (the "level 3" metric).

| Problem text                             | Cause                   | Affecting |

| Broadband-Low-Speed                      | Broadband Clarity watch | Health    |
| Cellular-Signal-Strength-Below-Threshold | Cellular Clarity watch  | Health    |

\*If the code {{ProblemTextReplacement}} is used in the customised alert, then **Delay-Exceeds-SLA** is replaced with **Delay-Exceeds-Threshold**

#### Alert generation

Note that each level 2 metric above can trigger an alert so for example you may get an alert when a heat tile goes red caused by Inbound Link utilisation, then another alert caused by Outbound Link utilisation even though the tile is already red. The tile colour represents the worst case of all level 2 metrics associated with it.

### Fields available to include in an Alert Template

The text in Highlight email alerts is based on fields contained in an alert template, which is defined on a folder and inherited by its subfolders.

This section describes the available fields, and also notes if that field is included in our standard SNMP trap or webhook alert. Note: fields in webhooks may have a different name to those used in email alerts and webhook fields begin with a lower case, so the email field {{TimeStampUtc}} is equivalent to webhook field "timeStampUtc". Refer to [a full list of webhook fields](/status/alerting/alerting-webhooks).

The text in alerts can be changed and additional text can be added. [Contact us](/getting-started/contact-us) to alter your email alerts.

### Stability issue codes

Highlight alerts have the option of containing a field representing the bearer issue which caused the alert to be triggered.

This section contains the issue codes and the text explanation.

<table><thead><tr><th width="125">Issue code</th><th>Issue description</th></tr></thead><tbody><tr><td>#CNA</td><td>Issue Code Not Available</td></tr><tr><td>#OIU</td><td>Ongoing issue cause unknown or monitoring an unknown interface</td></tr><tr><td>#TBO</td><td>Transients or brief outages</td></tr><tr><td>#DRP</td><td>Device restarted powered off/on</td></tr><tr><td>#RAD</td><td>Circuit reported as Down</td></tr><tr><td>#OOS</td><td>Circuit taken out of service</td></tr><tr><td>#UOT</td><td>Unknown event type</td></tr></tbody></table>


# Alert Suppression using Site Links

### Overview

Alert suppression effectively disables alerts for a location when the following conditions are met:

1. Main bearers are marked as a Site Link (done by an admin user)
2. All Site Link bearers at the location are alerting for stability

Alerts will be sent for the main Site Link bearers only. Alerts for other bearers, performance tests and other associated watches will be suppressed.

Note: Alert suppression is automatically applied for any location with at least two bearers marked as Site Links.

### How it works

This feature is explained with the following example.

Currently, the location tile for Data Centre is showing as red for stability issues.

<figure><picture><source srcset="/files/uWdI0zhTQ37Nhh1gLchi" media="(prefers-color-scheme: dark)"><img src="/files/mDjnXveE7GDaDQF0wzbM" alt="Data Centre Heat Tile"></picture><figcaption></figcaption></figure>

The location Data Centre has two main bearers (DC Primary & DC Secondary) marked with a Site Link check on the Admin, Edit watch dialog.

<figure><picture><source srcset="/files/F57Od6WS8w8gQ5VQ24Kd" media="(prefers-color-scheme: dark)"><img src="/files/AhWBEOa18D1uA6pjplsw" alt="Edit Watch Site link"></picture><figcaption></figcaption></figure>

* DC Primary has two associated performance tests.
* DC Secondary has two associated performance tests and one VLAN.
* There is one other bearer at this location, a Wireless Controller with two associated WAPs. This controller is not marked as a Site Link.
* There are 10 watches in total at this location.

Email alerts have been set for the folder (KFV Services) which contains the location Data Centre. Find about more about [alerting.](https://support.highlight.net/help/Status/alerting)

<figure><picture><source srcset="/files/foYNa9rm4BLCdZDdO7VD" media="(prefers-color-scheme: dark)"><img src="/files/QpRyJEN5fQdwa2vM63bl" alt="Alert for Site Link"></picture><figcaption></figcaption></figure>

Previously, if both main Site Link bearers were down for stability, your inbox might contain alerts for each bearer, all tests and other associated watches. In this example, nine 'Alert when issue starts' emails could have been sent. With alert suppression, only two emails are sent, one for each Site Link bearer.

Alerts will be suppressed for:

* other bearers at this location (in this example, the Wireless Controller)
* for any associated performance tests
* other associated subwatches

until either of the main bearers are once again green for stability. You may still receive 'Alert when issue clears' emails at this point. Note: If Webhook or SNMP trap alerts have been set up, these will also be suppressed.


# Alerting - Email

### Overview

Alerts are immediate notification if there are issues with your network or services. Alerts are set up and customised by you. You define when, how and who to be notified. You set the criteria including which specific metrics are key, whether you want notifying outside business hours, who should be informed (mailing lists or multiple email addresses can be configured) and which folders or locations are included in the alert. You can create as many alerts as needed.&#x20;

This page covers email alerts, our most common alert method. Refer to other pages for information on alerting via [webhook](/status/alerting/alerting-webhooks) or [SNMP trap](/status/alerting/alerting-snmp-traps).

{% hint style="info" %}
Alert emails are sent from the   **<noreply@highlight.net>**   address
{% endhint %}

All information collected by Highlight is compared with thresholds to ensure things are running smoothly. Some thresholds can be set by Admin users. Find out more: [alerting thresholds.](https://support.highlight.net/help/admin/alerting_thresholds)

The Create/Edit/Inherited Alert dialog behaves differently if you are creating a new alert, editing an existing alert or viewing an inherited alert. See details for each dialog type on this page.

### Alerting table

**Create new:**  Use to create a new alert&#x20;

**Search alerts:**  You can search on name, ID, the contents of the **Send to** field and the path shown in **Defined in**. Click **X** to clear the search&#x20;

**Show in subfolders:**  If checked then all alerts that are defined in folders or locations below the current one will be shown, this setting will be remembered when you next log in

If there are existing alerts, the table shows the columns below. By default, the table is sorted by ID number. Click on a column header to sort by another column or reverse the order   .

<figure><picture><source srcset="/files/p6DjyN6ZzsZIs0ZBqT7k" media="(prefers-color-scheme: dark)"><img src="/files/RMXAK4toJwRetOENHRcm" alt="Alerting table"></picture><figcaption></figcaption></figure>

(Cog):  Click on the cog or anywhere on an existing alert row to edit or delete it

**Name:**  Name alerts to differentiate them. The first 20 characters of the name are displayed. The name is red if the alert is disabled or suppressed at the current folder&#x20;

**Type:** All alerts are watch alerts currently

**ID:**  Shows the number which uniquely identifies each alert. Any alert change will appear in theReporting Audit Log against this number&#x20;

**Method:**  Email, [Webhook](/status/alerting/alerting-webhooks) or[ SNMP Trap](/status/alerting/alerting-snmp-traps)

**Send to:**  Shows one or more email addresses, a webhook URL or an IP address for SNMP traps&#x20;

**React on:**  Stability, Load, Health or any combination of these, in black if selected, greyed out if not selected

**React when:  Amber** or **Red** and Issue starts (triangle), Issue clears (square) or both, in black if selected, greyed out if not selected

**Defined in:**  Shows path to the alert's folder. If  Show in subfolders is checked then all alerts that are defined in folders or locations below the current one will be shown with a compressed path to the subfolder or location, hover to view the full path

**Status:**  Alert enabled or disabled/suppressed

### Create alerts

To create an alert, first, select the folder from the Network Explorer tree. From the Status area, click Alerting then **Create new**. The following dialog box slides in from the right:

<figure><picture><source srcset="/files/JfC0ztD8fiD82rcJ9dxX" media="(prefers-color-scheme: dark)"><img src="/files/PeMLeRH8Z6MdwhFhTtXo" alt="Alert dialog"></picture><figcaption><p>Alert dialog</p></figcaption></figure>

**Status:**&#x20;

Enabled - By default a new alert is enabled and Status in the table is a check

Disabled - Toggle to disabled which means no alerts are sent and Status in the table is a cross

**Name:**  Alerts can optionally be given a name of up 100 characters, this is useful to identify different alerts

***

**Defined in:**  This level shows on create

**Method:**  Email, [Webhook](/status/alerting/alerting-webhooks) or [SNMP Trap](/status/alerting/alerting-snmp-traps)

**Send to:**  This field is required but what is entered differs by alert method

**Email:**  shows your email address by default but can be changed, separate multiple addresses with commas

**Webhook:** enter a URL generated by the webhook receiver, see [alerting via webhook](/status/alerting/alerting-webhooks) for more details

**SNMP Trap:** enter the DNS name or IP Address of the SNMP trap receiver, see [alerting via SNMP trap ](/status/alerting/alerting-snmp-traps)for more details

***

**Alert on type:**  By default, send alert for all watch types or deselect some to stop them sending an alert.  Note: deselecting all means no alerts will be sent

<figure><picture><source srcset="/files/loDoriQWqPcDxPV74NI3" media="(prefers-color-scheme: dark)"><img src="/files/2ECr6suzRFvvU2dk8rdz" alt="Edit alert dialog - Alert on type"></picture><figcaption><p>Alert on type</p></figcaption></figure>

***

**React on:**  Check to select which type(s) of issue will cause an alert to be raised Stability (default), Load, Health or any combination of these. If none are selected, no alerts will be generated.

**When issue:**  Check to select Issue starts, Issue clears or both (default)

**If watch turns:**  Choose either **Amber** when first seeing an issue (default) or **Red** when an issue has continued for a period of time

**During:**  Choose either **All hours** for alerts which happen at any time (default) or **Business hours**. Find out more:[ Business hours](https://support.highlight.net/help/admin/business_hours)

***

**Visibility:**  Shown only if you are a service provider and determines if the alert will be visible to all users and customers, or just to service provider internal staff. There are two options:

**Customer:** any user can view, edit and delete this alert

**Internal:** customers cannot view, edit or delete this alert as it is only seen by service providers

On save, a unique ID number is created for each alert allowing you to track who made changes to an alert. The ID is visible in the alerting table, when editing an alert and in Reporting Audit Log as the item name.

### Edit alerts

If you are at or above the folder or location where an alert was originally created, you may edit it. Under the Status area, click Alerting then click on an existing alert to edit or delete it. A dialog like the one above slides in from the right.

Alerts cannot be moved. During edit, all the fields described in the **Create alerts** section above can be changed. The options listed here are only available in edit mode.

**Defined in:**  Shows the path to where the alert was created with two possible options:

"This level" the alert is defined in the current folder

The alert is defined in a subfolder

Shown for alerts with suppressed subfolders only:

**Suppressed: N**  If any subfolders are suppressed for this alert, view the total number (N); otherwise, this text is not shown

Expand the list to view the path to each subfolder that has this alert suppressed, long paths are shortened with an ellipsis

Use to remove the suppression on a subfolder

**Delete:** Only available in edit mode

### Inherited alerts

If you are in a folder or location below where an alert was originally created, you may view an alert but not edit it. Using the Status field, you may be able to suppress the alert which stops all alerts being sent for the folder you are in and any subfolders.

<figure><picture><source srcset="/files/iy2WkAdrhSxsp1VTvpOI" media="(prefers-color-scheme: dark)"><img src="/files/RVu7z0bsgXNa3z9mynY1" alt="Alert suppressed at subfolders"></picture><figcaption><p>Alert suppressed at subfolders</p></figcaption></figure>

**Status:**&#x20;

Enabled  - By default an inherited alert is enabled and Status in the table is a check

Disabled  - Toggle to **Alert suppressed at this level and below** to disable the alert at this folder and for all subfolders. The alert status in the table is a cross "Suppressed" when viewed in a suppressed folder

**Alert suppressed at this level and below** This message is shown if the alert you've opened is suppressed at a folder above your current position in the tree (see example below)

**Enabled** This message is shown if your current position in the tree is a location and the alert you've opened is enabled at a folder above (see example below)

**Defined in:** Shows the path to where the alert was created

Suppression is available at the folder level not at the location level<br>

In this example, the alert ID: 55322 to <support@kfv-services.com> was created in the **KFV Services** folder. Thus it can only be edited in that folder.\
In the subfolder **Datacentre** the alert is read-only but can be disabled, as shown in the above image.\
In the next level down, **Subfolder**, the alert is fully read-only with no save button available. Since it is suppressed in the parent folder (Datacentre) it's not available for suppression in this folder, as shown in the following example.

If you view an inherited alert at the location level, no changes can be made. It cannot be disabled or enabled and the save button is disabled, as shown below.

### Navigation message

**Cancel:** The confirmation message below shows if you have made any changes on the create/edit alert and then click Cancel or click on another location or folder in the tree without first saving changes

**Keep editing:** Closing the **Confirm navigation** dialog with the cross is the same as clicking this button


# Alerting - SNMP Traps

### Overview

Alerts can send SNMP traps to other systems and management platforms. Typically these systems will be high-level managers, or alert aggregators, and you will only be setting up this type of alerting if you are an administrator or engineer responsible for interconnecting a number of separate platforms.

SNMP traps are simple, immediate datagrams and can be sent when any metric on which Highlight is reporting exceeds a threshold.

### Alert Setup

In the Edit Alert dialog box (example below) two specific fields for setting up SNMP trap alerts are:

<figure><picture><source srcset="/files/tRKx4rB52DxamVDAWPQm" media="(prefers-color-scheme: dark)"><img src="/files/t7sjkChH72nt8AVoT09t" alt="Alerting Create Alert SNMP Trap"></picture><figcaption></figcaption></figure>

**Method:**  SNMP Trap

**Send to:**  the DNS name or externally-visible IP address of the SNMP trap receiver of the management platform (required field)

Refer to the [alerting page](/status/alerting/alerting-email) for details on all other fields in the create/edit dialog.

#### Notes

Highlight uses a default community string of “highlight” which is sent as part of the trap. There is no ability to change this when setting up a trap alert.

The source IP of the trap is determined by the Highlight system you logon to. Therefore it will be the IP address associated with DNS name *system*.highlighter.net where *system* is usually the name of your service provider.

### SNMP Trap MIB

Traps are sent based on the Highlight Trap MIB (HIGHLIGHT-TRAP-MIB), the latest version of which is available via email from [Highlight Support](broken://pages/1yoo8M0lEwunU7BVS8j9). Traps contain the following information:

<table><thead><tr><th width="199">Information</th><th width="120">Format</th><th>Details</th></tr></thead><tbody><tr><td>Watch ID</td><td>Number</td><td>Highlight’s ID number for the Watch which generated the alert</td></tr><tr><td>Watch Name</td><td>String</td><td>The short name (reference, mnemonic etc.) for the Watch</td></tr><tr><td>Folder Name</td><td>String</td><td>The name of the folder containing the Watch</td></tr><tr><td>Location Name</td><td>String</td><td>The name of the location containing the Watch</td></tr><tr><td>Level 3 metric</td><td>Number</td><td>Stability, Load or Health</td></tr><tr><td>Level 2 metric</td><td>Number</td><td>A reference for the element causing the alert, e.g. LinkStability</td></tr><tr><td>Metric value</td><td>Number</td><td>Current value of the level 2 metric, as a percentage</td></tr><tr><td>Fuel-gauge value</td><td>Number</td><td>Current value of the fuel-gauge which triggered the event</td></tr><tr><td>Description</td><td>String</td><td>Text description of the broken metric</td></tr><tr><td>Timestamp UTC</td><td>String</td><td>The UTC time at which the alert was raised</td></tr><tr><td>Timestamp local</td><td>String</td><td>The local time at which the alert was raised</td></tr><tr><td>Reporting Device</td><td>IP Address</td><td>The IP Address the trap came from</td></tr><tr><td>Switch critical port slot**</td><td>Number</td><td>The slot of the port if a critical port switch event</td></tr><tr><td>Switch critical port**</td><td>Number</td><td>The port if a critical port switch event</td></tr></tbody></table>

\*\*Optional OID only added to the trap if it's a switch critical port alert

You will need to load or install this MIB into your management platform (the application which receives traps).


# Alerting - Webhooks

### Overview

Highlight can send outbound alerts via a webhook, enabling easier integration with service management tools and other systems. Typically you will only be setting up this type of alerting if you are an administrator or engineer responsible for interconnecting a number of separate platforms.

### Alert Setup

In the Create Alert dialog box (example below) two specific fields for setting up webhook alerts are:

<table><thead><tr><th width="137"></th><th></th></tr></thead><tbody><tr><td><strong>Method</strong></td><td>Webhook</td></tr><tr><td><strong>Send to</strong></td><td>Enter a URL generated by the webhook receiver (required field)</td></tr><tr><td>Test button</td><td>Is available for webhook alerts only and sends a sample webhook (see next section) to the URL</td></tr><tr><td><mark style="color:green;">Connected</mark></td><td>Testing confirms the URL is valid </td></tr><tr><td><mark style="color:red;">Cannot connect</mark></td><td>Shown if the URL is not valid, for possible reasons refer to <a href="https://support.highlight.net/help/troubleshoot/alerting#symptom_7_webhook_alert_issues"><mark style="color:red;">Troubleshooting webhook alerts</mark></a></td></tr><tr><td><strong>Notify on failure</strong></td><td><p>Shows your email address by default but can be changed. Separate multiple addresses with commas.<br>If there's a problem with a webhook, Highlight sends an email to this address with this information:</p><ul><li>Subject: Webhook endpoint temporarily disabled</li><li>Webhook name</li><li>Webhook ID</li><li>Webhook URL</li><li>Link to webhook</li><li>Reason for failure</li></ul><p>This field is optional. Delete the email address if you do not wish to receive an email.</p></td></tr><tr><td><strong>Save button</strong></td><td>On save, a unique ID number is created for each alert allowing you to track who made changes to an alert. The ID is visible in the alerting table, when editing an alert and in Reporting Audit Log as the item name.<br>When saving a webhook alert, a test of the <strong>Send to</strong> URL is performed. This test must be successful to save the alert.</td></tr></tbody></table>

Refer to the [alerting page](/status/alerting/alerting-email) for details on all other fields in the create/edit dialog.

# Sensitivity

### Overview

Heat tiles are a smart way to look at network issues, whether it’s stability, load or health. However, as Highlight is capable of live alerting via email, webhook and SNMP trap, you can modify the rate at which watches change colour and therefore, generate alerts. This page details changing the sensitivity at the folder or location level. It's also possible to set a sensitivity profile on an individual watch, see the **Sensitivity profiles per watch** section below.

Find out more about [configuring alerts](/status/alerting/alerting-email). From Status Alerting all users can access the Sensitivity panel; only users with the permission **Manage Folders/Locations,** can edit the sensitivity settings.

<figure><picture><source srcset="/files/GmPHc4NVlBtmfxfli8Hw" media="(prefers-color-scheme: dark)"><img src="/files/YTQyvHRSF81FCkeSaj9a" alt=""></picture><figcaption></figcaption></figure>

You can define how quickly watches react to issues by moving the sliders for stability, load and health. Initially everything will be greyed out. To make a change for a specific folder or location you will need to click **Override Settings** which will then override the inherited setting and allow you to set new sensitivity levels for the folder or location you are in and all folders below it. You can always remove any local settings you have created by selecting the **Clear Local Settings** option and the sliders will revert to the inherited values.

### Sensitivity profiles per watch

It's possible to change sensitivity at the individual connection (watch) level. This means at a location with two types of connection, a leased line can continue to react quickly if down, but a broadband line can be set to react slowly.

<figure><picture><source srcset="/files/92wsyjs0wFvn6yKpDn5B" media="(prefers-color-scheme: dark)"><img src="/files/7WhP91ba0seykqGUxkSh" alt="Sensitivity Profile"></picture><figcaption></figcaption></figure>

The polling frequency for each watch (which is typically 1, 3 or 5 minutes) is shown in the edit watch dialog. This is useful to determine the time from when an issue starts until alerts are sent and watches/tiles change colour.

For multiple new watches you can set the sensitivity profile using our bulkload process.

You can discover the polling frequency and sensitivity profiles for bearer watches by running the [Admin watch report](/reporting/admin-reports/watch-report).

Find out more about [edit watch](https://support.ci.highlight.net/help/admin/edit_watch#main_tab_upper_sections). [Contact us](/getting-started/contact-us) for more information about sensitivity profiles per watch.

### Sample numbers

<figure><picture><source srcset="/files/JoUu9C3caYnGgxRvFt9d" media="(prefers-color-scheme: dark)"><img src="/files/iY1m90an3DzTgYj4XfVp" alt="Sensitivity Sample Numbers"></picture><figcaption></figcaption></figure>

The numbers to the right each category tell you how many samples need to be received before Highlight reacts:

bad samples    the number of bad samples to go amber then red from full health

good samples    the number of good samples to revert to amber then green from fully unhealthy

In the example shown above a fully healthy watch will go amber after 5 bad samples, and if the issue is ongoing it will go red after a further 5 bad samples (total 10).\
Assuming a 3 minute polling cycle, it would therefore take approximately 15 minutes to change a green watch to amber and another 15 minutes to turn it red.

{% hint style="danger" %}
Note:  If the watch is not fully healthy, for example it has just turned green from being amber, it may only take one bad sample to turn the watch amber again as that sample will cause the watch score to drop below the amber threshold.\
Thresholds are further explained in Advanced settings below.
{% endhint %}

### Basic settings

The graphic below shows how Highlight can be configured to react quickly to issues but return more gradually to a state of full health. The watch with an issue (and its associate location tile) will change from green to amber when the amber threshold in crossed and from amber to red when the red threshold is crossed. Email alerts are also sent (if configured) when the thresholds are crossed.

<figure><img src="/files/hUsaiMlcDmigiiNmsEa8" alt=""><figcaption></figcaption></figure>

In the example here, stability is set to react quickly (slider at rightmost position 5), and health is set to react slowly (slider at leftmost position 1).

<figure><picture><source srcset="/files/b5ozcrpLIgLC6ueSZ52O" media="(prefers-color-scheme: dark)"><img src="/files/kJfrH4D47vvnwQHDDdnp" alt="Sensitivity Basic Example"></picture><figcaption></figcaption></figure>

#### React quickly

(Stability in the above graphic)

* **Going sick:**

  Because of the react quickly setting, the first bad sample will turn a green watch amber and the next bad sample will then turn the watch red.
* **Returning to healthy:**

  Once the watch is red because of stability, it will turn amber after 2 good samples and green after 1 additional sample.

#### React slowly

(Health in the above graphic)

* **Going sick:**

  Because of the react slowly setting, it would take 20 bad samples to turn a green watch amber and an additional 20 to turn it red.
* **Returning to healthy:**

  Once the watch is red because of health, it will turn amber after 24 good samples and green after 24 additional samples.

#### Slider Values

|                 | To go Sick (from full health) |           | To go Healthy (from fully unhealthy) |             |

**Notes:**

* 5 is the rightmost slider position, 1 the leftmost
* “To go Sick” is the number of bad samples in a sequence required to go amber or red, from full health (green)
* “To go Healthy” is the number of good samples in a sequence required to go amber or green from no health (red)
* As an example, slider position 3 will cause the watch to go amber on receipt of the 5th bad sample which, for a 3 minute polling cycle, will be 12 minutes after the first bad sample is detected
* A **bad** sample can be one with a) no response, b) exceeds thresholds, or c) contains test failures
* A Highlight sample comprises the processed result from an SNMP request to a monitored device, one sample for every polling cycle. Separate samples are collected for line health, switches and performance tests, plus autodiscovered elements - classes, VLANs, multilinks, and tunnels.

### Advanced settings

If you want more granular control over reaction speed, select **Advanced** and you can set individual thresholds, increments and decrements. We recommend only doing this if you understand these settings or [contact us](/getting-started/contact-us) for additional explanation. Selecting **Advanced** will display the watch colour thresholds, and changes associated with bad or good samples, based on a score of 1000 being full health. To adjust the amber/red thresholds either use the slider or type in a new value.

<figure><img src="/files/OORegf2q2C2sC3Dw2vOs" alt=""><figcaption></figcaption></figure>

The graphic above shows how Highlight can be configured with precise amounts ( Bad sample is 200) to react quickly to issues but return more gradually to a state of full health ( Good sample is 150). The watch with an issue (and its associated location tile) will change from green to amber when the amber threshold in crossed and from amber to red when the red threshold is crossed. Email alerts are also sent (if configured) when the thresholds are crossed. See the Advanced example for Stability (below) for a written explanation.

<figure><picture><source srcset="/files/Nvmu4o2olFfQbcKCYsmc" media="(prefers-color-scheme: dark)"><img src="/files/XmnVAvcSBffFRAd29uKP" alt="Sensitivity Advanced Example"></picture><figcaption></figcaption></figure>

To adjust the amber/red thresholds either use the slider or type in a new value. The number of samples required to change the colour will automatically adjust to reflect the new settings. Similarly type in new decrement (Bad sample) and increment (Good sample) settings as required, and once completed click **Save**&#x20;

**Undo** will revert settings to the last save. **Basic** will revert an individual slider to position 3 irrespective of its previous position.

#### Advanced example:

(Stability in the above graphic)

| Sample sequence         | Sample type | +Increment/-Decrement | Watch score | Tile colour |
| ----------------------- | ----------- | --------------------- | ----------- | ----------- |
| **Fully green**         | Good        | +150                  | 1000        | Green       |
| **+1**                  | Bad         | -200                  | 800         | Green       |
| **+2**                  | Bad         | -200                  | 600         | Amber       |
| **+3**                  | Bad         | -200                  | 400         | Red         |
| **+4**                  | Bad         | -200                  | 200         | Red         |
| **Fully red**           | Bad         | -200                  | 0           | Red         |
| **(From fully red) +1** | Good        | +150                  | 150         | Red         |
| **+2**                  | Good        | +150                  | 300         | Red         |
| **+3**                  | Good        | +150                  | 450         | Amber       |
| **+4**                  | Good        | +150                  | 600         | Amber       |
| **+5**                  | Good        | +150                  | 750         | Green       |
| **+6**                  | Good        | +150                  | 900         | Green       |
| **Full health**         | Good        | +150                  | 1000        | Green       |

* **Becoming unhealthy:**

  Because Bad sample is set to 200 it will only take 2 bad samples to pass the amber threshold of **680** from full health, and turn the watch from green to amber, and an additional bad sample to pass the red threshold at **420** and turn the watch from amber to red.
* **Returning to healthy:**

  The Good sample setting is 150 so, if starting from a score of 0 (fully unhealthy), it will take 3 good samples to pass the red threshold of **420** and turn the watch from red to amber, and an additional 2 good samples to reach the amber threshold at **680** and turn the watch from amber to green.
* **Returning to healthy if not fully unhealthy:**

  For this example if only 4 bad samples in a sequence had been received, our starting score would be 200 and it will only take 2 good samples to pass the red threshold of **420** and turn the watch from red to amber (score now = 500), and an additional 2 good samples to reach the amber threshold at **680** and turn the watch from amber to green.

#### Advanced further example:

(Health in the above graphic)

* **Becoming unhealthy:**

  Because Bad sample is set at 500 it will only take 1 bad sample to pass the amber threshold of **750** from full health (and turn the watch from green to amber) and an additional bad sample to pass the red threshold at **250** (and turn the watch from amber to red).
* **Returning to healthy:**

  Because Good sample is set to 250 it will only take 1 good sample to reach the red threshold of **250** (and turn the watch from red to amber) and an additional 2 good samples to reach the amber threshold at **750** (and turn the watch from amber to red).

**Note:** Watches normally turn amber/red more quickly than when they are returning to healthy. This is to allow for repeatedly receiving a bad sample followed by a good sample ("flapping"). After a period of time, the watch would still turn amber and eventually red to show there's an issue.


# AppVis


# AppVis

### Overview

At a glance, you can quickly identify the applications running on your network with recognised logos for each one. This page shows details of all applications discovered in or beneath the selected folder or location in the Network Explorer tree. You can also group applications and filter the display to show only groups of most interest. By default the top 10 items by highest usage are shown. Each discovered application shows:

* the application logo, name and category
* the total number of locations where the application has been seen
* dates when it was first and last seen
* DSCP values and classes used, and assigned groups
* a usage figure
* plus a breakdown of all locations and classes

### Drilldown and Trend chart

#### Drilldown details

* locations where this application has been seen as a clickable link (at the folder level) or text only (at a location), locations will be repeated if the application is using more than one DSCP value
* traffic specific First/Last Seen dates
* DSCP names and values
* classes in use
* usage as both a value and representative purple bar. Hover on the bar to see a percent of the overall usage figure for the selected folder. Tiny percentages will show as <1%

Note: Information in the drilldown area is ordered by highest usage

#### Trend chart

The trend chart shows usage for each day of the month from the time period selected. It's a useful view of application usage over time. Hover over each bar to see the actual usage for each day.

### View Options

* **Sort:** has the following options:
  * **Name, Category or Class:** alphabetical, A to Z or Z to A
  * **First or Last Seen:** date order, New to Old or Old to New
  * **DSCP, Usage or Locations:** numerical, High to Low or Low to High
* **Results:** by default 10 applications are shown or change to 30, 100 or 500

{% hint style="info" %}
The selected **time period, date, sort** and **results** options will remain for the duration of the session. These options will reset to their default values when you logout. However, any applied group filters will be remembered when you next log in.
{% endhint %}

* **Period:** only available when a month is selected in the time navigation bar, see Time Period section above
* **Classes:** allows you to display only certain classes and turns bright blue when any boxes are unchecked. Note: The classes filter impacts the drilldown areas, the trend charts and the CSV downloads as well as the top level applications.\
  The classes listed are those defined in the folder [class definitions.](https://support.highlight.net/help/admin/ccd#changing_the_ccd)
* **Groups:** allows you to display only certain groups and turns bright blue when any boxes are unchecked, see Groups section below

**Download as CSV:** adjust your page view (for example 30 applications in group Critical sorted by First Seen) then download the data to a CSV file. The CSV shows the drilldown data for each application.

### Groups

{% hint style="info" %}
**User permission**

All users can filter the display to show only groups of most interest, and the groups filter setting will be remembered the next time you log in.\
However only users with permission **Manage applications** can create/edit groups or assign applications to groups and will see the cog and **Add new group** button.  More details on [user permissions](https://support.highlight.net/help/admin/create_user#permissions) are available.
{% endhint %}

#### Groups filter

This list contains 3 default system groups which cannot be changed:

**New** (folder):  indicates an application is new to the selected folder/organisation

**New** (location):  indicates an application is new to a location or new to a DSCP value, but not new to the organisation

**Ungrouped:**  after 7 days marked as new, an application will automatically move to ungrouped

# Categories

### Overview

Below are the 24 application categories as predefined by Cisco NBAR2 with some example applications listed for each category. If no logo is available for an application, one of these generic category logos will be shown instead.

# Header

### Overview

Full description of the Details page options, titles, time zones and calendar settings

<figure><picture><source srcset="/files/mSEY3M8kHU658W2noBZr" media="(prefers-color-scheme: dark)"><img src="/files/G16WQ5HlbCeejv26I9Lk" alt="Details Header"></picture><figcaption><p>Details Header</p></figcaption></figure>

### Title bar

The title bar comprises 2 parts, plus a temporary purple marker if a watch is in maintenance. See [the Maintenance section below](#maintenance) for details.

#### Upper part

The header  varies according to the watch type. Titles show:

* In larger text, description (if completed) otherwise watch name
* watch type (product type, if completed, will display instead of watch type for bearers)
* bandwith (for bearers, traffic classes, VLANs and multilink)
* watch name

#### Lower part

The lower part of the title bar -

is the path to the location of this watch. Clicking on any part of the path (Root, KFV Services, etc.) will move to that level on the Network Explorer tree. This is standard across all Highlight pages.

Hovering over the star  allows you to add this location or folder to favourites. See [Using Favourites](/getting-started/useful-information/favourites) for more information.

### Details menu

<figure><picture><source srcset="/files/O3x6QUyYkejb3JtO2Tjf" media="(prefers-color-scheme: dark)"><img src="/files/TF6b3Z8YTvRqCGO6fPph" alt=""></picture><figcaption><p>Details menu </p></figcaption></figure>

Most users see **Tech info**, **Alert log**, **Change** and **About**. Those with "Edit Watches" permission see **Edit** instead of **Change**.  All options are explained in more detail below.

#### Tech info

This window shows detailed information about the device you selected. Refer to[ Tech Info in Reporting Inventory](/reporting/inventory#tech-info) for details.&#x20;

#### Alert log

Use this to see alerts from this watch location in the [Alert Log](/reporting/alert-log). The Alert Log is filtered to match the date range selected on the Details page. All users have access to the Alert Log.

To return from the Alert Log to the Details page, right-click on your browser's back button \[←] and select **Details - Highlight**.

This option is not available for dates before the Alert Log was implemented in April 2021.

#### Change

This launches your mail client and generates an email to your customer services group as listed on the Home page. The subject, watch name, location and folder auto-fill.

Use this option to request a change to the watch, location or folder you're looking at on the Details page: perhaps the bandwidth is wrong, the name or description needs changing, or you think there's an issue.

#### Edit

Use this to open the [Edit Watch dialog](https://support.highlight.net/help/admin/edit_watch) for the watch currently on the Details page. Make any changes if needed, Save and return to the Details page.

If you Delete the watch, you will return to the Status Heat Tiles page for the position you have selected in the Network Explorer tree.

{% hint style="info" %}
&#x20;**Permission needed:** You will only see the **Edit** option if you have the permission **Edit watches.**
{% endhint %}

#### About

Details includes a Provider link which displays the logo of your service provider, as defined in the Domain folder. Click on the logo to get service provider support details.

### Time zone, business hours and page refresh

<figure><picture><source srcset="/files/EZjUY9UXzA5hd83D9kAV" media="(prefers-color-scheme: dark)"><img src="/files/tqb0DvJ71GYnFtVoX3tj" alt="Details page Header - Time Zone, Business Hours and Refresh"></picture><figcaption></figcaption></figure>

#### Time Zone

Three time zone options are available:

* The location time zone, as defined during setup
* Your time zone, being that detected from the user's browser
* UTC

#### Business Hours

By default, charts on the Details page show non-business hours with a vertical grey background and business hours with a vertical white background on day and week views. Business hours are not shown on a month view. Toggle off to show alternate horizontal grey and white background areas. This setting is remembered when you next log in.

Find out more about [business hours.](/details/details-page-options/background-colours#business-hours-grey-white-backgrounds)

#### Refresh Options

The Details page is static by default with Auto Refresh Off

Alternatively, switching AutoRefresh On, will countdown from 180 seconds until the Details page refreshes

### Calendar control

<figure><picture><source srcset="/files/ZDSRwc4OCkpHxNvmv237" media="(prefers-color-scheme: dark)"><img src="/files/YkI4pRh2pfBxxD1u00ZX" alt="Calendar control showing weeks"></picture><figcaption></figcaption></figure>

Use the drop-down to select the time period of:

<table data-view="cards"><thead><tr><th></th><th></th></tr></thead><tbody><tr><td>Day</td><td>A single 24 hour period (may be 23 or 25 hours on daylight savings adjustment dates)</td></tr><tr><td>Week</td><td>A Highlight week is Sunday to Saturday</td></tr><tr><td>Month</td><td>A calendar month beginning on the first</td></tr></tbody></table>

Use the **Today** option on the right of the time bar to view the current date for the time zone displayed

### Maintenance

# Colour coding

Sections on the Details page change colour to indicate where the issue is

### Today only&#x20;

When viewed for today only, the header for each section on the Details page gives an indication if it is currently impacting the associated heat tile colour. This applies for collapsed sections also - see next section.&#x20;

<table data-view="cards"><thead><tr><th></th><th></th></tr></thead><tbody><tr><td>No colour / grey / green</td><td>No issue or for week, month or any day other than today</td></tr><tr><td><mark style="background-color:orange;">Amber</mark></td><td>At least one issue, this watch is alerting, meaning a threshold has been breached</td></tr><tr><td><mark style="color:red;">Red</mark></td><td>At least one issue and ths watch has been alerting for some time</td></tr></tbody></table>

{% hint style="success" %}
This colour coding applies to all watch types (except Flow and NBAR) on today only.&#x20;
{% endhint %}

#### Amber example

<figure><picture><source srcset="/files/3bD739KudvGwjngU5ZCO" media="(prefers-color-scheme: dark)"><img src="/files/oSJjLBtvjvKYTOhLZDxc" alt="Amber watch"></picture><figcaption><p>This Traffic Load section is amber. The Outbound load has been exceeding the 80% threshold for more than 30 minutes.</p></figcaption></figure>

#### Red example

<figure><picture><source srcset="/files/30I9tdEwkaxA6McMWZH5" media="(prefers-color-scheme: dark)"><img src="/files/ZXtR4CaQVoOp9JNSSJc1" alt="Red watch"></picture><figcaption><p>This Line Availability section is red. There has been an ongoing issue for more than 6 hours.</p></figcaption></figure>

### Collapsed sections

<figure><picture><source srcset="/files/YqmK4i0tekuleoQIjhCw" media="(prefers-color-scheme: dark)"><img src="/files/wNbCC4oVBMU70haq9H9v" alt="Collapsed sections with colours"></picture><figcaption></figcaption></figure>

Even when collapsed, you can see the current state of the 4 performance tests associated with the parent tunnel. &#x20;

* Two are without colour indicating they have no issues
* One is amber indicating the beginning (or end) of at least one issue
* One is red indicating at least one ongoing issue&#x20;

There is an overall colour on the Performance Analysis section which applies for the collapsed section also. This overall colour will reflect the test in the worst state, red in this example.


# Background colours

On a details page chart, grey backgrounds indicate non-business hours and purple backgrounds indicate maintenance periods.

### Business hours - Grey/White backgrounds

<figure><picture><source srcset="/files/penO7mr2q3QV0ut3E0k8" media="(prefers-color-scheme: dark)"><img src="/files/3o6YLjuBVoFZeYpQNmqI" alt="Details chart business hours"></picture><figcaption></figcaption></figure>

By default, the chart shows non-business hours with a vertical grey background and business hours with a vertical white background on day and week views. Business hours are not shown on a month view. Toggle off to show alternate horizontal grey and white background areas.

Business hours are the time periods (to the nearest hour) that a business is operational. Highlight uses business hours when displaying charts on the Details page, filtering reporting results and generating alerts. Default values are 06:00 to 18:00 Monday through Friday with Saturday and Sunday excluded. However, you may see different settings if the business hours on a parent folder or location have been changed. Business hours reflect the local time zone for the location.

Find out more about [business hours.](https://support.highlight.net/help/admin/business_hours)

### Maintenance periods - Purple backgrounds

<figure><picture><source srcset="/files/gWAszIAIlIOHbslSHUaR" media="(prefers-color-scheme: dark)"><img src="/files/n3N4zGO6KxdI0pJ7R1n7" alt="Maintenance periods on charts"></picture><figcaption></figcaption></figure>

Any purple background areas on the chart show current and past maintenance periods. Watches in maintenance do not send alerts, change the colour of heat tiles or decrement the availability figure for the time period.

Find out more about [maintenance indicators on the details page](/details/details-page-options/maintenance-indicators).


# Maintenance indicators

### Overview

This page shows the indicators in place for current and past maintenance periods.  [Putting watches into maintenance windows is an admin task.](https://support.highlight.net/help/admin/create_container#maintenance_tab) &#x20;

{% hint style="info" %}

#### In maintenance  <picture><source srcset="/files/DCPpkgHz04jexgzIfnFF" media="(prefers-color-scheme: dark)"><img src="/files/JrKVRD5I67SN056HBH2v" alt="Maintenance indicator"></picture>

Watches in maintenance do not send alerts, change the colour of heat tiles nor decrement availability figures
{% endhint %}

### Details page - Header

When a watch is in maintenance, the maintenance icon shows in the header

<figure><picture><source srcset="/files/Om4iMKsPJ82LfhmWIxS4" media="(prefers-color-scheme: dark)"><img src="/files/OJBAEhZELK6QSv7LEH4r" alt="Details page Maintenance indicator"></picture><figcaption></figcaption></figure>

Hover on the maintenance icon to see:

* the name of the container/maintenance window ("Maintenance ON 24x7 Container" in the image)
* the time remaining in the maintenance window ("9h 14m" in the image); less than one minute remaining will show as "<1m"
* if you see a number in brackets (2), this means there's more than one maintenance window in effect for this watch. The time remaining is when the first maintenance window is due to end. This time will then adjust to show how long until the next maintenance window is due to end.

### Details page - Background colours

Find out more about [Details page background colours](/details/details-page-options/background-colours#maintenance-periods-purple-backgrounds).&#x20;

### Details page - Performance test

When a performance test is in maintenance, you will see a purple background area on the chart and a marker showing:

* the maintenance icon&#x20;
* the name of the maintenance window ("Maintenance ON 24x7 Container" in the image above)
* the time remaining in the maintenance window (8h 29m in the image above). If it's less than one minute remaining, "<1m" shows.
* if you see a number in brackets (2), this means there's more than one maintenance window in effect for this test. The time remaining is when the first maintenance window is due to end. This time will then adjust to show the next maintenance window in effect.


# Standard / MinMax toggle

This page describes the behaviour of the Standard / MinMax toggle on the Details page

**Actual:** Show volume of data received or sent

[**Standard / MinMax** toggle](/details/details-page-options/standard-minmax-toggle)&#x20;

**Dormant watches** are not expected to pass traffic so a small amount in or out (more than 1000 Kbps by default) changes the side bar colour. Find out more about [alerting thresholds](https://support.highlight.net/help/admin/alerting_thresholds).

#### Saved settings

The settings below will be remembered when you next log in.

* Whether the panel is collapsed or expanded
* The status of any toggles

### Colour coding

When viewed for today only, each section on the Details page gives an indication if it is currently alerting and thus impacting the associated heat tile colour. Find out more about [colour coding](/details/details-page-options/colour-coding).&#x20;

### Traffic Load description

Download the traffic information to a CSV file, see the [Download option](#download-option) section

**Vertical axis:**  Changes from "%" when **Percentage** selected and "bps" when **Actual** selected - hover on the chart to see exact values. Note: scaling may adjust units depending on the volume

**80% default threshold:**  On the percentage chart only, the threshold is shown as a horizontal purple line on the chart with the actual threshold value on the far right.\
The default threshold is 80% and [Admin users can set a custom threshold](https://support.highlight.net/help/admin/alerting_thresholds#bearers). If configured, a load alert can be sent when the traffic load approaches the threshold.\
If the adjusted vertical axis means the threshold line is not visible then a purple arrow is shown indicating the threshold is above the visible chart area.

**Horizontal axis:**  Adjusts according to the selected time period to show "hours" in day view and "days" in week and month views; redraws if the time zone is changed at the top right of the Details page.  See [Zoom options](/details/details-page-options/zoom-options) for methods to zoom in on the data.&#x20;

<table><thead><tr><th width="134.5999755859375">Colour</th><th width="129.20001220703125">Percentages</th><th>Meaning</th></tr></thead><tbody><tr><td>Black Red</td><td>300%</td><td>Percentages are capped at 300%</td></tr><tr><td>Maroon</td><td>200%</td><td></td></tr><tr><td>Red</td><td>101%</td><td>Greater than the bandwidth of the line</td></tr><tr><td>Pink</td><td>100%</td><td>The configured or discovered bandwidth of the line</td></tr><tr><td>Orange</td><td>80%</td><td>By default, Highlight alerts at 80%</td></tr><tr><td>Amber</td><td>60%</td><td></td></tr><tr><td>Green Amber</td><td>20%</td><td></td></tr><tr><td>Green</td><td>0%</td><td></td></tr></tbody></table>

Highlight displays the load value for each data point in the time period:

<table data-view="cards"><thead><tr><th></th><th></th></tr></thead><tbody><tr><td>Day</td><td>Shows multiple data points per hour (one for each polling period, usually one to five minutes)</td></tr><tr><td>Week</td><td>Shows 24 data points per day (every hour), in <strong>MinMax</strong> view, Average for each hour is shown along with MinMax values</td></tr><tr><td>Month</td><td>Shows 6 data points per day (every 4 hours), in <strong>MinMax</strong> view, Average for each 4 hour period is shown along with MinMax values</td></tr></tbody></table>

Day view and Week/Month view with "Standard" selected. Hover on a point to see timestamp and Max for In and Out as actual values and percentages. Errors/Discards and CPU are included.

Week/Month view with "MinMax" selected. Hover on a point to see timestamp, then Avg, Min and Max for In and Out as actual values and percentages of the bandwidth. Errors/Discards and CPU are included.

{% hint style="info" %}
**From week/month view**  Clicking any data point jumps to the selected day view. All new chart types are synchronised and so jump to the same day together.
{% endhint %}

### Summary

The summary shows the total values, peak and 95th percentages for in and out during the selected time period

<figure><picture><source srcset="/files/mEkgLGh6t3PxDfIuYv5T" media="(prefers-color-scheme: dark)"><img src="/files/xu67QwBPPcYHvKa0rRPG" alt="Traffic Load Summary"></picture><figcaption><p>Summary with percent selected</p></figcaption></figure>

The values shown change based on the selection of Percent or Actual in the side bar.\
**Percent** values are coloured on the same gradient as the chart, from green meaning light load, to orange and red as the value approaches 100% of the bandwidth and deeper reds above 100%.\
**Actual** values are blue to indicate neither good nor bad.

**Total:**  Shows the accumulated volume of traffic for the time period displayed, calculated by adding the volumes from the polled samples. This value is the same with Percent or Actual selected.

**Peak (Percent)**

The bits per second values reported are taken from the individual sample with the highest percentage of the configured/discovered line speed for the time period displayed. It will be seen as the highest point on the chart.\
Percentage can exceed 100% if bursting is permitted on the line or the line speed in Highlight is lower than the configured or discovered bandwidth.

**Peak (Actual)**

The bits per second value reported is from the individual sample with the highest throughput for the time period displayed. It will be seen as the highest point on the chart. The Highlight peak therefore is the sample with the largest volume, divided by the number of seconds between samples (typically 180 or 60).&#x20;

**Note:** This may vary from the peak reported on a network device which would use a different measurement interval.\
The peak bps figure may differ from the peak bps on the Percentage chart if the Highlight bandwidth has changed during the day. See [Troubleshooting traffic load](https://support.highlight.net/help/troubleshoot/traffic_load#symptom_4_percentage_v_actual_bps_charts) for more details.

**95th percentile:**  The highest recorded value during the time period ignoring the top 5%, read more about [the 95th percentile and why it's useful](/reporting/network-reports/output#id-95th-percentile-load)

**Last sample:**  Only shown for today, this is the last recorded value (the last good sample) for today with **?** shown if no data was received

### Errors/Discards and CPU utilisation

**Errors** are inbound line errors (such as CRC and frame errors). Line errors are not available for Class of Service watches.\
**Discards** are the outbound issue of packet loss.\
Both are measured as a percentage of overall packets received (Errors) or sent (Discards). Hover on the chart to see timestamp and precise values. Colours on the line are:

<table><thead><tr><th width="96.79998779296875">Colour</th><th width="102.4000244140625">Ignored</th><th width="105.5999755859375">Green</th><th width="106.4000244140625">Green Amber</th><th width="102.39996337890625">Amber</th><th width="100">Orange</th><th>Red</th></tr></thead><tbody><tr><td>Errors/Discards</td><td>Up to 0.10%</td><td>0.11 to 0.50%</td><td>0.51 to 1.00%</td><td>1.01 to 2.50%</td><td>2.51 to 5.00%</td><td>Greater than 5.00%</td></tr></tbody></table>

{% hint style="info" %}
**Custom defined** Alerting threshold: Bearers - Congestion & Errors
{% endhint %}

By default, line errors and discards greater than 1.00% will cause the heat tile to change colour and generate an alert if one has been set up. [Admin users can set a custom threshold](https://support.highlight.net/help/admin/alerting_thresholds#bearers).

From the Traffic Load title bar you can download to a CSV file the errors and discards data from each poll, see the [Download option](#download-option) section for more details.

***

**CPU utilisation** is shown as a grey line if unavailable or a thicker green line up to 50%. Hover on the chart to see timestamp and precise values. Above 50% it's shown in coloured blips:

<table><thead><tr><th width="89.60003662109375">Colour</th><th width="82.39996337890625">Grey line</th><th width="104.800048828125">Green line</th><th width="116">Green</th><th>Amber</th><th width="113.5999755859375">Orange</th><th>Red</th></tr></thead><tbody><tr><td>CPU util</td><td>0%</td><td>Up to 50%</td><td>51% to 65%</td><td>66% to 80%</td><td>81% to 95%</td><td>96% to 100%</td></tr></tbody></table>

Highlight does not change the colour of heat tiles nor send alerts for CPU utilisation.\
Note: CPU utilisation may not be available, depending on the equipment manufacturer.

### Download option

From the Traffic Load title bar you can  download to a CSV file the traffic information which created the displayed charts.

The columns in the download are:

<table><thead><tr><th width="100.20001220703125">Column</th><th>Description</th></tr></thead><tbody><tr><td>Time</td><td>the date and time of each sample (matching the time zone selected on the Details page)</td></tr><tr><td>In</td><td>the total bytes received since the previous sample</td></tr><tr><td>Out</td><td>the total bytes sent since the previous sample</td></tr><tr><td>Util In</td><td>the average speed of traffic calculated from the received bytes value during this time period, expressed as a percentage of the configured/discovered bandwidth In (see example below)</td></tr><tr><td>Util Out</td><td>the average speed of traffic calculated from the sent bytes value during this time period, expressed as a percentage of the configured/discovered bandwidth Out (see example below)</td></tr><tr><td>Error</td><td>the number of errors reported in this time period expressed as a percentage of the number of packets received</td></tr><tr><td>Discards</td><td>the number of discarded packets reported in this time period expressed as a percentage of the number of packets sent</td></tr></tbody></table>

{% hint style="info" %}
For SD-WAN tunnels, disregard the columns Util In, Util Out, Error and Discards as the data is not returned
{% endhint %}

#### Utilisation example

If 491595485 bytes are received over a 3 minute period on a 50M line, the Utilisation is calculated as:\
491595485 \* 8 = 3,932,763,880 bits\
/ 180            = 21,848,688 bits/sec\
/ 1,000,000 = 21.85Mbps\
/ 50M \*100 = 43.7% utilisation

#### Utilisation note

The timespan used for calculations of utilisation can vary by a few seconds from the specific poll interval. This may be caused by a number of factors including:

* SNMP retries
* slow device responses
* resource contention on the poller

This variation is taken into account when Highlight calculates the utilisation which is presented on screen and in the Utilisation columns. This can lead to differences in utilisation calculations if attempts are made to reverse the calculation assuming a specific poll interval.

### Zoom options

There are two methods to zoom in on charts: drag and click. Find out more about [zoom options.](/details/details-page-options/zoom-options)

### Background colours

Grey backgrounds indicate non-business hours and purple backgrounds indicate maintenance periods.  Find out more about [background colours](/details/details-page-options/background-colours).


# Line Availability

### Overview

<figure><picture><source srcset="/files/WF5PV1JvdZRUu5fFcNEl" media="(prefers-color-scheme: dark)"><img src="/files/CaDJxPY0ZQTePDcx27bd" alt="Line Availability Chart"></picture><figcaption></figcaption></figure>

This charts three types of availability events. Hover on the chart to see timestamp and additional details:

**Impacting:**  typically outages, these have a duration and impact availability

**Exclusions:**  events removed through planned maintenance or manual exclusion with SLA Now

**Non-impacting:**  events which do not impact availability

The Line Availability section provides additional detail about the coloured blips on the Availability lines. The Event list can also be used to exclude specific events from Highlight's availability calculations. This is useful if a maintenance period occurred but was not scheduled in advance or if an incident happened which was not the fault of the service provider. Highlight will show Operational and Adjusted availability figures in the Summary and the [SLA Compliance report](/reporting/network-reports/suggested-reports#sla-compliance-report).

### Download option

Download the information to a CSV file to see all events for the selected time period (day, week or month) and any comments on events. The list is not affected by any Event list filter or by zooming in on the chart.

In the CSV download, events which have been excluded show:

**Type:**  Excluded

**Impacting:**  no

**Impacting Duration:**  00:00

**Comment:**  as entered by the user who excluded or included the event

### Options

The options below are all checked by default, uncheck to remove the events on each line from the chart. This also removes them from the Event list. Read more about each event type in the **Availability event details** section below.

<table><thead><tr><th width="117" data-type="checkbox"></th><th></th></tr></thead><tbody><tr><td>true</td><td>Impacting</td></tr><tr><td>true</td><td>Exclusions</td></tr><tr><td>true</td><td>Non-impacting</td></tr></tbody></table>

Impacting (3)

The number in brackets after each event type indicates how many of that event have occurred in the selected time period (day, week or month). In the image, there were a total of 3 impacting events comprised of 1 brief outage and 2 down events. The numbers in brackets cover the entire time period and do not change if unchecked or when the chart is zoomed in.

**Indeterminate:**  A line in any top checkbox indicates a mix of checked and unchecked sub-checkboxes

***

**Event list:**  Unchecked by default, check to see more details for each event during the selected time period - read more about the[ event list in the section below](#event-list-general)

#### Saved settings

The settings below will be remembered when you next log in:

* Whether the panel is collapsed or expanded
* The status of all checkboxes

### Colour coding

When viewed for today only, each section on the Details page gives an indication if it is currently alerting and thus impacting the associated heat tile colour. Find out more about [colour coding](/details/details-page-options/colour-coding).&#x20;

### Line Availability description

Download button:  Download all events for the selected time period to a CSV file - see separate section above

**Horizontal axis:**  Adjusts according to the selected time period to show "hours" in day view and "days" in week and month views; redraws if the time zone is changed at the top right of the Details page.  See [Zoom options](/details/details-page-options/zoom-options) for methods to zoom in on the data.&#x20;

#### Time period

For each event type, total duration for the time period (day, week or month) selected are shown. These are not affected by any Event list filter or by zooming in on the chart.

* **Total event durations by type:**  a cumulative duration of all events in the selected time period split into:
  * Impacting
  * Exclusions
  * Non-impacting
* **Operational availability:**

  the percentage of time this watch was available in the time period; this will not include time before the device was activated nor outages during maintenance.
* **Adjusted availability:**

  the availability figure which is calculated using non-excluded impacting events. If no events are manually excluded, operational and impacting availability figures match. Refer to the **Event list: Exclude events from availability calculations** section below for details on how to exclude impacting events.

**Operational and adjusted availability** correspond to the figures shown in the [SLA Compliance report](https://support.highlight.net/help/reporting/report_suggestions#sla_compliance_report) for the same period.

### Event list: General

**Event list:** Unchecked by default, check to see more details for each event during the selected time period

This list provides additional detail about the coloured blips (known as events). For the selected time period (day, week or month) each event shows its type, the time and date it occurred, the event details, duration and if it is impacting the availability figure or not.

The header shows **Showing X of Y events** where Y is the total number of events for the time period including events in maintenance. X is a reduced number if filters are applied.

Download the information to a CSV file to see all events and any comments - read more about [the Download option](#download-option) in the section above

#### Sort

By default, events are sorted by date and time with the most recent event at the top. This can be reversed or you can sort by any of the column headers:

**Type:**  Events are:  impacting,  excluded,  maintenance or  non-impacting

**Time|Date\*\***  Sort by event start time \[default]

**Event Details:**  An alphabetical sort of events

**Comment:**  An alphabetical sort of comments (only relevant on excluded events)

**Duration:** Show longest duration events first or last

**Impacting:**  Sort by  impacting or  non-impacting

#### Search

Use the Search events field to show specific **Event Details** and comments. If an incident number is reliably included with a comment, you can search for it.

### Event list: Exclude events from availability calculations

Users with the permission to **Manage maintenance** have two ways to exclude an outage from Highlight's availability calculations:

#### 1. Before the event - set up a maintenance window

Refer to the Help & Support Centre for details on [creating containers ](https://support.highlight.net/help/admin/create_container)and putting them into maintenance

Purple background areas on the chart show current and past maintenance periods. Watches in maintenance do not send alerts nor change the colour of heat tiles.

#### 2. After the event - exclude an outage

<figure><picture><source srcset="/files/LM5aZTBWgPaX4TPDwlSv" media="(prefers-color-scheme: dark)"><img src="/files/s972KmtdeDFJJNwhMvjO" alt="Line availability excluding events"></picture><figcaption></figcaption></figure>

Notice the following in the above GIF:

1. Only events on the impacting line can be excluded
2. You can select more than one event at a time
3. A comment is required to enable the button

After exclusion:

1. The red impacting icon  in the Event list turns to a grey exclusion icon&#x20;
2. The comment is added to all events excluded at the same time
3. The impacting icon changes from impacting to  non-impacting
4. On the chart, the excluded events move from the impacting line to the exclusions line
5. In the Summary, the Adjusted availability figure increases whilst the Operational availability figure is unchanged

{% hint style="info" %}
Events can only be excluded if the parent folder has SLA Now enabled on the Features tab and the user has **Manage maintenance** permission
{% endhint %}

**Exclude selected:** Check one or more impacting events, then add a comment and select this button

**Include selected:**  To reverse exclusions, check those events which have previously been excluded (labelled "Excluded" ), add a comment and select this button

{% hint style="warning" %}
A comment is required each excluded event. We recommend including an incident number in the comment. This can then be searched for using the text filter in the dialog, in the CSV download or in the Audit log.
{% endhint %}

Event exclusions are recorded in the [Audit Log](/reporting/audit-log) against the watch with details of which user made the change, any comment and when.

Events which have been excluded have the following characteristics:

* Type is "Excluded"
* **Duration:**  the duration of the event will be faded    AND EITHER
* the maintenance icon which shows "Event occurred whilst watch in maintenance" on hover   OR
* A comment in the Comment column

In the CSV download, events which have been excluded show:

**Type:**  Excluded

**Impacting:**  no

**Impacting Duration:**  00:00

**Comment:**  as entered by the user who excluded or included the event

The number of exclusions made and adjusted availability show in the [SLA Compliance report](/reporting/network-reports/suggested-reports#sla-compliance-report) with a red background if the availability figure is less than the SLA target.

### Availability event details

Affects the Stability metric

The impacting line shows how available your connection has been. Availability is worked out as a percentage of the day, week or month that the watch was monitored. Several issues will cause outages which are shown as coloured blips on this line and decrease the availability percentage.

Show the event list for a full list of issues and outages, with exact timestamp and duration

Note: Ongoing and not contactable blips can be custom configured to be included in Total outages or not. This is set by the service provider at a folder level and inherited by subfolders unless overridden. If excluded from total outages, then the duration is shown in grey text to indicate it is excluded from the total outages figure and does not affect Operational availability.

The entries you may see are summarised in this table with full details below:

<table><thead><tr><th width="70" data-type="number">Number</th><th width="94">Blip colour</th><th width="271">Issue</th><th width="323">Effect in Highlight</th><th>Included in Total outages? </th></tr></thead><tbody><tr><td>1</td><td>Amber</td><td>Transient or brief outages</td><td>Decrements stability</td><td>Yes</td></tr><tr><td>2</td><td>Red</td><td>Circuit reported as down, or period of non-contact ends in a device restart</td><td>Stability previously decremented<br>(only red after contact re-established)</td><td>Yes</td></tr><tr><td>3</td><td>Maroon</td><td>Circuit taken out of service</td><td>Decrements stability</td><td>Yes</td></tr><tr><td>4</td><td>Turquoise</td><td>Device configuration changed</td><td>No effect</td><td>No</td></tr><tr><td>5</td><td>Black</td><td>Device restarted, powered off/on</td><td>No effect</td><td>No</td></tr><tr><td>6</td><td>Mint</td><td>Unknown event type</td><td>No effect</td><td>No</td></tr><tr><td>7</td><td>Blue</td><td>No data, device not contactable or monitored interface does not exist</td><td>Stability previously decremented<br>(only blue after contact re-established)</td><td>Custom</td></tr><tr><td>8</td><td>Mustard</td><td>Ongoing issue, cause unknown or monitoring an unknown interface</td><td>Decrements stability and turns watch amber/red</td><td>Custom</td></tr></tbody></table>

#### 1. Amber: Brief outage

**Overview**

Shown as an amber blip, these are brief outages which indicate the link being monitored went down and came up again very briefly between the times Highlight polled it. Highlight can tell this has happened because the device timestamps the last interface change, so if the state changed between consecutive successful polls there must have been a brief outage.

For example, if this link state timestamp had increased between the check at 00:00 and the check at 00:03, we know the line was briefly down between those times, even though it looked healthy both times we checked it.

**Cause**

For a brief outage blip to be drawn, the line must be down for less than the polling period. The outage may have lasted for a few seconds, a minute or more. When the line comes back up, it will take a short time for routing to settle down, the router to start passing packets again, then for any connections using it to timeout and retry, so the effective outage will be longer. Highlight counts each transient outage as one minute of downtime, which is a sensible estimate.

#### 2. Red: Down

This is where we regain contact with the device after an outage and establish that the monitored link definitely went down. The mustard (ongoing) blips will turn red. Like other red issues, this counts as a formal outage on your watch, shown by a red blip and the comment 'Circuit reported as down.' The availability percentage for that watch will be decreased.

A red line also occurs if a period of non-contact ends in a device restart.

#### 3. Maroon: Out of service

If the monitored link has been shut down deliberately on the device, the event is 'out of service.'

#### 4. Turquoise: Configuration changed

This indicates a change in the configuration of the monitored device itself and is shown as a turquoise blip.

#### 5. Black: Device restarted

This is where the monitored device has been powered off/on or restarted and is shown by a black blip. If the link itself was down before the device was restarted you will see red blips with the last blip being black. For more details see point 6 below (Red: Circuit reported as down).

#### 6. Mint: Unknown

If the event type cannot be determined, the type is 'Unknown' (event type)

#### 7. Blue: Not contactable

If the last change timestamp for the monitored interface hasn't changed when connection is re-established after connectivity problems, Highlight knows that the line has been up all the time and we simply lost contact because of a problem elsewhere on the network. Highlight marks these events by turning mustard blips to blue with the comment 'No data : Device not contactable.' There was no outage detected by the device, although it was not reachable from the Highlight platform.\
The availability percentage is not decreased unless the folder option to treat blue as an outage is set to Yes.

A blue blip will also be shown if Highlight was previously set to monitor an unknown interface; or if the device does not support the "last change" parameter, unless the period of non-contact ends in a device restart which would cause the mustard blips to turn red.

#### 8. Mustard: Ongoing

When Highlight loses contact with the device it is monitoring, we treat the outage as an ongoing connectivity issue shown by a mustard blip. Only once Highlight reconnects with the device we check the last change timestamp for the monitored interface, which determines if:

* the link went down whilst we were out of touch with it (the mustard colour changes to red 'down'); or
* the link did not go down (the mustard colour changes to blue 'not contactable'); or
* the period of non-contact ends in a device restart (the mustard colour changes to red 'down')

A mustard blip will also be shown if Highlight is set to monitor an unknown interface.

# Cellular Clarity

### Overview

This chart shows the signal strength for the cellular line over time. It also shows changes in cell tower ID, network and radio technology. The chart is only available for lines which have been set up as **Cellular Clarity** by an admin user.

<figure><picture><source srcset="/files/k9GU2Ljb87JOCER1tdIk" media="(prefers-color-scheme: dark)"><img src="/files/d01t9iTjN2uevc3jt75T" alt="Cellular Clarity Chart"></picture><figcaption></figcaption></figure>

### Colour coding

When viewed for today only, each section on the Details page gives an indication if it is currently alerting and thus impacting the associated heat tile colour. Find out more about [colour coding](/details/details-page-options/colour-coding).&#x20;

### Cellular Signal Strength description

#### Download

For day view only, download the information to a CSV file&#x20;

**Vertical axis**

Shows scores from 0.0 (Poor) to 5.0 (Excellent). Excellent values are green and near 5 whilst poor values show in red and are closer to 0. Hover on the chart to see exact values.

**4.0**

The threshold is shown as a horizontal purple line on the chart with the actual threshold value on the far right. If configured, a health alert can be sent when the signal strength drops below the threshold.

**Horizontal axis**

Adjusts according to the selected time period to show hours in day view and days in week and month views; redraws if the time zone is changed at the top right of the Details page.

Note: When signal strength is lost, Highlight shows this as a gap in the chart. Whilst there is no signal strength, there is also no information on cell tower ID, network or radio technology so Highlight registers these values as 0 or null. Changes to null values are not shown as blips - only changes to genuine values are shown.

**Tower:**  Shows blips for changes in the cell tower ID\
Cradlepoint: Tower changes are not reported in Highlight as the data is not provided by the device

**Network:**   Shows blips for changes in the network - for example Vodafone to O2

**Radio:**  Shows blips for changes in the radio technology - for example LTE to Wcdma

#### Time period

Highlight displays the average recorded value for each signal strength data point in the time period:

<table data-view="cards"><thead><tr><th></th><th></th></tr></thead><tbody><tr><td>Day</td><td>Shows multiple data points per hour (one for each polling period, usually five minutes)</td></tr><tr><td>Week</td><td>Shows 24 data points per day (every hour), Average for each hour is shown along with Min/Max values if selected</td></tr><tr><td>Month</td><td>Shows 6 data points per day (every 4 hours), Average for each period is shown along with Min/Max values if selected</td></tr></tbody></table>

{% hint style="success" %}
**RSRP default**\
If Highlight receives both RSRP and RSSI metrics, RSRP is used to generate the score. The tooltip shows RSSI in grey for information only. RSSI is used only when RSRP is "Unknown".
{% endhint %}

**From week or month view:** clicking any data point jumps to the selected day view.&#x20;

### Signal Strength Score

Highlight collects two signal strength metrics for a cellular connection: RSRP and RSSI. RSRP is a more accurate, precise metric and usually only available on 4G/5G connections (aka LTE). RSRP is the preferred default metric used to calculate a score between 0 (Poor) and 5 (Excellent). RSSI is only used when RSRP is not available. Using a signal strength score enables Highlight to easily handle a cellular connection which is swapping between 4G/5G (RSRP) and 3G (RSSI).

Scores are equivalent to the values as shown in this table:

| Score      | Meaning   | RSRP range     | RSSI range     |
| ---------- | --------- | -------------- | -------------- |
| 5          | Excellent | -83 and higher | -61 and higher |
| 4.0 to 4.9 | Excellent | -84 to -92     | -62 to -70     |
| 3.0 to 3.9 | Good      | -93 to -102    | -71 to -79     |
| 2.0 to 2.9 | Good      | -103 to -111   | -80 to -87     |
| 1.0 to 1.9 | Fair      | -112 to -121   | -88 to -96     |
| 0.1 to 0.9 | Poor      | -122 to -129   | -97 to -104    |
| 0          | Poor      | -130 and lower | -105 and lower |

If a threshold has been set then Highlight will send alerts when the score falls below the threshold consistently over a period of time. Refer to [the Alerting Threshold dialog.](/admin/admin-general-details/alerting-thresholds#cellular)

**When no Signal Strength values are available**

If we do not get a reading on RSRP nor on RSSI, then the score is set to Unknown with the following effects:

* On the chart, there's a gap in the data and no tooltip, unless Tower/Network/Radio are collected then tooltip shows Unknown for Score, RSRP and RSSI.
* On the chart daily CSV, the Score, RSRP and RSSI all show as blank/empty.
* For Alerting, Highlight decrements the Health fuel gauge for the watch for NULL values only if the threshold is set >0. This will eventually change the colour of the side bar - amber then red and send alerts if configured.
* For Reporting, Highlight excludes NULL periods when calculating the average.
* For Reporting API, no change.

# Performance Charts

### Overview

Highlight displays the results of performance tests in colourful charts which are visually powerful and easy to interpret. The charts are drawn in slightly different ways depending on which test is used

### Description

Highlight performance tests provide visibility of key measurements such as round trip time (RTT), packet loss and jitter between two points on your network. These metrics give a great overview of how healthy a connection is and are often the basis of Service Level Agreements (SLA) between provider and customer.

Performance test results are shown graphically in a chart for instant understanding of how network delay changes in relation to the traffic, health and application fluctuations over time.

Performance testing works over most network types and can be measured across specific Classes of Service (when implemented), proving that prioritised applications within an MPLS network are performing correctly. This ongoing visibility can be the basis for future performance tuning, as new applications and requirements are introduced.

Highlight's integration with Cisco ThousandEyes means you can add an API key to a ThousandEyes controller in Highlight and set it to automatically discover ICMP Ping and HTTP Server tests.

Like other performance tests, Highlight shows a chart for each test on a details page with the parent performance agent. This means you can group ThousandEyes performance tests with other services in a single Highlight location. You can then use all the existing performance test functionality in Highlight with these tests.

### Colour coding

When viewed for today only, each section on the Details page gives an indication if it is currently alerting and thus impacting the associated heat tile colour. Find out more about [colour coding](/details/details-page-options/colour-coding).&#x20;

### Header, Options and Maintenance

#### Maintenance

Note:[ Performance tests in maintenance](/details/details-page-options/maintenance-indicators#detail-page-performance-tests) do not send alerts nor change the colour of heat tiles.&#x20;

#### Controls and axes

If the test is currently in maintenance, this indicator is shown

If the test is discontinued, this indicator is shown, find out more about [discontinued SD-WAN tests](https://support.highlight.net/help/details/tunnel#discontinued_tunnels_and_performance_tests)

***

**Vertical axis**

Automatically adjusts to show all the data points for the selected period (day, week or month). Hover on the chart to see exact values.

The adjusted vertical axis means it may not start from 0. A chevron is shown if this is the case.

**98%**\
**within**\
**300 ms**

The threshold is shown as a horizontal purple line on the chart with the actual threshold value on the far right. The text shows the percentage of tests within threshold.\
If configured, a health alert can be sent when the delay goes above the threshold.\
If the adjusted vertical axis means the threshold line is not visible then a purple arrow is shown indicating the threshold is above or below the visible chart area.

**Horizontal axis**

Adjusts according to the selected time period to show hours in day view and days in week and month views; redraws if the time zone is changed at the top right of the Details page.

***

**Focus/All Data**

**Focus:** By default, the chart is scaled to focus on the data. This means show the maximum value data point up to twice the threshold value. Data points above twice the threshold are not shown in Focus mode.\
**All Data:** Toggle to show all data points for the time period. If there are no outliers, then there is no difference between Focus and All Data.

***

By default, ThousandEyes tests show the test name on the external system rather than the test type (HTTP Server for example).

As shown in the image below, if **Dashboard - Display link** is checked on the parent controller then the name of each performance test on the performance agent details page is also a link to that test in the ThousandEyes dashboard.

### HTTP Server

This chart shows the total time between two points known as the source and the target. A data point is plotted for each test on a day, with the average and min/max shown for week and month. The colour shows the test response compared with the threshold: green when measurements are within threshold turning red when measurements exceed the threshold. The failures line shows a red blip representing errors.

#### Data granularity

Highlight displays the recorded values in the following ways:

<table data-view="cards"><thead><tr><th></th><th></th></tr></thead><tbody><tr><td>Day</td><td>This depends on the test frequency set on the external system</td></tr><tr><td>Week</td><td>Shows 24 data points per day (every hour), Average for each hour is shown along with Min/Max values</td></tr><tr><td>Month</td><td>Shows 6 data points per day (every 4 hours), Average for each period is shown along with Min/Max values</td></tr></tbody></table>

Day view - hover on a point to see timestamp and total time in milliseconds plus any error. If there is no error or an HTTP error, then Status and Response are shown. For any other error type, Status and Response show "N/A". For total time, a green dot indicates tests at or below the threshold, a red dot indicates results are above the threshold. A green dot is shown for Error = None, a red dot shows for anything other than None.

Week or month view - hover on a point to see average, minimum and maximum values for total time plus a count of the failures against the total polls in the period.

{% hint style="info" %}
**From week/month view**  Clicking any data point jumps to the selected day view.
{% endhint %}

#### Failures

Failures are shown as a red blip when an error occurred. It's a grey line if there was no error. Hover on the chart to see timestamp and precise values. On week and month view, errors are counted for the time period (one hour on a week view, 4 hours on a month view).

The full list of possible errors is:

* None - no error
* DNS
* Connect
* TLS (formerly SSL)
* Send
* Receive
* HTTP
* Content

Refer to [ThousandEyes documentation for a definition of each error](https://docs.thousandeyes.com/product-documentation/tests/http-server-tests/using-the-http-server-view).

### ICMP Ping, UDP Echo and TCP Open

ICMP Ping, UDP Echo and TCP Open tests all use the same type of chart:

<figure><picture><source srcset="/files/VDKCuMC558zVILW9Ma9V" media="(prefers-color-scheme: dark)"><img src="/files/BZvQihte5aogY2d1vXFh" alt="Perforamance chart - UDP Echo"></picture><figcaption><p>Perforamance chart - UDP Echo</p></figcaption></figure>

This chart shows the delay between two points known as the source and the target. A spot is plotted for each test on a day, with the average and min/max shown for week and month. The colour shows the test response compared with the threshold: green when measurements are within threshold turning red when measurements exceed the threshold. The failures line shows a coloured blip representing the percentage packet loss.

#### Data granularity

Highlight displays the recorded values in the following ways:

<table data-view="cards"><thead><tr><th></th><th></th></tr></thead><tbody><tr><td>Day</td><td>Shows up to 6 data points per polling period (usually three minutes)</td></tr><tr><td>Week</td><td>Shows 24 data points per day (every hour), Average for each hour is shown along with Min/Max values</td></tr><tr><td>Month</td><td>Shows 6 data points per day (every 4 hours), Average for each period is shown along with Min/Max values</td></tr></tbody></table>

Day view - hover on a point to see timestamp and precise values for up to 6 results per polling period plus the failures percentage. Green dots are tests at or below the threshold, red dots are above the threshold. ∞ indicates a test that timed out/failed

Week or month view - hover on a point to see average, minimum and maximum values plus the failures percentage

{% hint style="info" %}
**From week/month view**  Clicking any data point jumps to the selected day view.
{% endhint %}

#### Failures

Failures are shown as a coloured blip where packet loss occurred. It's a grey line if unavailable or a thicker green line if available and 0%. Hover on the chart to see timestamp and precise values.

Failures represent the worst case - the number of failures divided by the total number of tests as a percentage.

<table><thead><tr><th width="94">Colour</th><th width="88">Green line</th><th width="104">Amber</th><th>Orange</th><th>Pink</th><th>Red</th><th>Maroon</th></tr></thead><tbody><tr><td>Packet Loss %</td><td>0%</td><td>0.01% to 20%</td><td>20.01% to 40%</td><td>40.01% to 60%</td><td>60.01% to 80%</td><td>80.01% to 100%</td></tr></tbody></table>

For example if Highlight collects 6 performance test results in a single poll and 2 of the 6 had failed (33%), an orange blip will be displayed.

### Precision Delay and MOS

Precision Delay and MOS use the same type of chart (with MOS values available only on the MOS test chart):

<figure><picture><source srcset="/files/8a1YYtBiFhibFZ3GkIuX" media="(prefers-color-scheme: dark)"><img src="/files/sqShcv9FogEF9PdI0fKy" alt="Performance Chart MOS"></picture><figcaption></figcaption></figure>

This chart shows the delay between two points known as the source and the target. The average and min/max are shown for day, week and month. The colour shows the average test response compared with the threshold: green when measurements are within threshold turning red when measurements exceed the threshold. There are 2 or 3 additional blip lines for jitter, loss and MOS.

#### Data granularity

Each test comprises sending 100 128-byte packets at intervals of 50 milliseconds. Green indicates tests at or below the threshold, red indicates tests above the threshold. Highlight displays the recorded values in the following ways:

<table data-view="cards"><thead><tr><th></th><th></th></tr></thead><tbody><tr><td>Day</td><td>Shows a data point per polling period (usually three minutes), Average for each test is shown along with Min/Max values</td></tr><tr><td>Week</td><td>Shows 24 data points per day (every hour), Average for each hour is shown along with Min/Max values</td></tr><tr><td>Month</td><td>Shows 6 data points per day (every 4 hours), Average for each period is shown along with Min/Max values</td></tr></tbody></table>

Day, week and month view - hover on a point to see timestamp and precise values per polling period plus the jitter, loss and MOS values

#### Jitter

Jitter is shown as a colour blip based on the calculated jitter value as a percentage of the configured jitter threshold. It's a grey line if unavailable. It's a thicker green line if available and up to 50% of threshold through to red (100% of threshold). It remains dark red if the threshold is exceeded.

# Bearers - Traffic Analysis


# NBAR & Flow

### Overview

Feature comparison of NBAR (a Cisco Application recognition utility) and Flow (a standards based analysis of data conversations) on the Details page.

A more detailed description of Flow can be found on the [Understanding Flow](/details/bearers-traffic-analysis/flow-specifics#overview) page.

### Options and colour coding

indicates the Traffic Analysis is Flow based(no Flow in heading) indicates the Traffic Analysis is NBAR based

**Options for Flow** are explained in [Understanding Flow Detail - Top Applications/Top Talkers](/details/bearers-traffic-analysis/flow-specifics#flow-detail-top-applications-top-talkers)

**Options for NBAR - for day view only**

1 Hour:  Show the graphs in hourly intervals (default)

30 Minutes:  Show the graphs in half-hourly intervals, this will reset to default (1 hour) when you next log in

**Today only**

Colour coding applies to all sections on the Details page except Traffic Trend and Traffic Analysis (Flow and NBAR). There are no targets for Traffic Analysis data and thus it does not impact any heat tile colours. The indicator will always be green for today.

### Overview - NBAR and Flow

Highlight supports bi-directional application visibility in one of two ways: via NBAR (Network-Based Application Recognition - Cisco only) or by Flow data (IPFIX, Cisco NetFlow v5 or v9, or Juniper J-Flow). These two technologies offer different pros and cons and these should be considered when selecting which application analysis tool to use.

Find out more about [Application Awareness.](https://support.highlight.net/help/functionality/application_awareness)

### Highlight Flow features

Refer to the [Understanding Flow](/details/bearers-traffic-analysis/flow-specifics) page for a full explanation of the Flow Details page.

#### Agent-based, distributed and scalable

Highlight Flow uses distributed agents (collectors) which receive Flow data directly from network devices, store and aggregate the raw data locally, compress it, and send this reduced data stream to the core Highlight platform. By distributing both storage and compression, Highlight Flow can remain accurate but also very scalable. Normally a single agent is placed within an enterprise network, although organisations can deploy multiple agents at strategic locations within large networks or where flow traffic must be kept to an absolute minimum.

The flow collector agent can run on a physical or virtual server and the server specification required can be found here: [Server Specifications](https://support.highlight.net/help/functionality/server_specs). The minimum specification flow collector is capable of processing flow data from 20 flow sources. The flow collector software is free from Highlight but there may be Highlight licence considerations. [Contact us](/getting-started/contact-us) for any questions regarding Flow.

The flow collector receives flow data from the customer routers via UDP port 9996 and once processed, posts this data every hour to Highlight, encrypted via HTTPS.

### Examples of Highlight Application Visibility Graphs

#### Flow

Note the option to select Applications or Hosts in the side bar. Refer to the [Understanding Flow](/details/bearers-traffic-analysis/flow-specifics) page for more details.

To set up a router for Flow, refer to the [Flow Configuration](https://support.highlight.net/help/device_setup/flow) page.

#### NBAR

NBAR does not have a Hosts option, but note the greater granularity of applications. On a day view, you can switch between hourly and 30 minute intervals.

Cisco routers can be configured to identify the ‘Unknown’ traffic. See the Highlight Support document for details on [identifying 'Unknown' Applications](https://support.highlight.net/help/device_setup/nbar#identifying_unknown_applications)


# Flow Specifics

### Overview

Flow provides visibility of Applications running on the network, showing top sources and destinations, plus top conversations for each. Detail is shown for each completed hour.

{% hint style="info" %}
Highlight can collect Flow data from compatible devices such as Cisco, Juniper, or Riverbed.

### Flow colour coding

Colour coding applies to all sections on the Details page except Traffic Trend and Traffic Analysis (Flow and NBAR). There are no targets for Traffic Analysis data and thus it does not impact any heat tile colours. The indicator will always be green for today and grey for any week, month or any day other than today.

### Flow Detail - Top Applications/Top Talkers

Once configured a Traffic Analysis (Flow) section will appear at the bottom of the Details page. The dialog displays the top 20 hosts/applications (plus others grouped together) with outbound traffic on the left, inbound on the right.

{% hint style="info" %}
&#x20;The settings will be remembered when you next log in.
{% endhint %}

#### Applications/Hosts

Applications:  Displays the top 20 applications (plus others grouped together) running across the selected link

Hosts:  Displays the top 20 hosts (plus others grouped together) sending across the selected link

Conversations:  Displays the top 20 conversations (plus others grouped together) either sending or receiving traffic (only data table view available, not graph)

#### Graph/Data table

Switch between graphical and text views of the information using the buttons provided. Display results for the current time period (as selected in the time bar at the top of the page). Show the top 20 hosts/applications (plus others grouped together) either sending or receiving traffic.

Graph:  Displays bar charts, as shown above, note: graphs are not available for conversations

Data table:  Displays text and has the option to break the data down further (by hour on a day view, day on a week view and week on a month view)

#### Today only

24 hour:  Displays the full day

Last hour:  Displays 6 segments of ten minutes each. If auto-refresh is on or the page is refreshed, the segments will shift to show the most recent with the oldest segment disappearing from the graph or data table. The times shown will adjust if the time zone is changed.

#### Graph only

Hover over each coloured section to see the percent of total traffic used by that host/application during the selected time period. The host/application name is also indicated in the list.

Uncheck a host/application to remove it from the graph, check only those of interest

**Show all / Top 5:** When there are more than five applications/hosts, toggle this button to show all or limit the list to the top five highest percent usage options. The buttons are not shown for fewer than five applications/hosts.

#### Data table only

Zoom in to display results for a specific time period. e.g on a day view, click 08 to display information accumulated for the hour from 8:00am to 9:00am.

### Flow Detail - Data table edit

**User permission:**  Only users with permission **Manage applications** can make changes to an application or host name, which will be visible to all users.

**Locations affected:**  Changes to an application name or host name will impact all locations in the same folder. To make name changes affect a wider range of locations, set the top level folder as [an application domain in Edit Folder on the Features tab](https://support.highlight.net/help/admin/create_tree#edit_a_folder).

When **Data table** is selected, you can edit the name of an application or host/IP using&#x20;

&#x20;Any change to Flow host or application names is recorded in Reporting, Audit Log

### Flow Detail - Conversations

Conversations:  This option displays the top 20 conversations (plus others grouped together) either sending or receiving traffic (only data table view available, not graph)

With **Data table** selected for applications or hosts, there is a further option to view a list of the top ten conversations involved with the entry.

#### By Application

If you clicked when looking at an application such as email, you'll see the ten busiest pairs of hosts using this application - in each case one inside your network, one outside it - along with the volume and percent of traffic each has created.

#### By Host

If you clicked when looking at a particular host system, such as a server, you'll see the top ten other systems this host is talking to and the application being used in each case. Highlight also lists the volume of data and percent being generated by each.

If the name of the host has been edited, then the original name will appear in the top line of the Window as **Host Name.**

### Flow Retention

Highlight will normally keep top 20 information for 12 months and detailed conversation information for 93 days.

### Flow Reporting

Reporting for Flow in Highlight is a technical listing extracted from the [Admin Watch report](/reporting/admin-reports/watch-report), which can be very useful as a means of identifying Flow watches that are no longer reporting. Alternatively, [contact us](/getting-started/contact-us) for customised Flow reporting options.&#x20;

When viewed for today only, each section on the Details page gives an indication if it is currently alerting and thus impacting the associated heat tile colour. Find out more about [colour coding](/details/details-page-options/colour-coding).&#x20;

### Client Count description

A vertical bar is drawn on the chart for each poll (typically every five minutes). When client numbers are at or below the threshold, the vertical bar is green. When client numbers exceed the threshold, the section of the vertical bar above the threshold is red.

#### Threshold

The custom defined threshold is indicated with a thin horizontal purple line and shown in purple text in the right margin. The threshold is 30 client devices by default and can be altered by Admin users. See [WiFi Alerting Thresholds](https://support.highlight.net/help/admin/alerting_thresholds#wifi) for more information.\
If configured, an alert can be sent when client count exceeds the threshold.

**Vertical axis:**  Scaling adjusts depending on data

**Threshold (30 clients):**  If the adjusted vertical axis means the threshold line is not visible then a purple arrow is shown indicating the threshold is above the visible chart area.

**Horizontal axis:**  Adjusts according to the selected time period to show "hours" in day view and "days" in week and month views; redraws if the time zone is changed at the top right of the Details page

### Time period

Highlight displays the values for each data point in the time period:

<table data-view="cards"><thead><tr><th></th><th></th></tr></thead><tbody><tr><td>Day</td><td>Shows multiple data points per hour (one for each polling period, usually one to five minutes)</td></tr><tr><td>Week</td><td> Shows 24 data points per day (every hour), Maximum for each hour is shown</td></tr><tr><td>Month</td><td>Shows 6 data points per day (every 4 hours), Maximum for each 4 hour period is shown</td></tr></tbody></table>

For any time period, hover on a point to see date, timestamp, client count and signal problem as a percentage.

### Signal Problems

Colours on the line represent the percent of clients with signal problems as:

<table data-view="cards"><thead><tr><th></th><th></th></tr></thead><tbody><tr><td><strong>Green</strong></td><td>Values are at or below the threshold</td></tr><tr><td><strong>Red blips</strong></td><td>Values exceed the threshold</td></tr><tr><td><strong>Grey</strong></td><td>No samples or client count of 0%</td></tr></tbody></table>

#### Threshold

The threshold for signal problems is set to 25% by default and can be altered by Admin users. This is 25% of clients on an AP with poor signal strength. A poor signal strength is defined as one or two bars or below 20 decibels. The custom threshold is shown in purple text in the right margin. See [WiFi Alerting Thresholds](https://support.highlight.net/help/admin/alerting_thresholds#wifi) for more information.\
If configured, an alert can be sent when signal problems exceed the threshold.

Refer to [WiFi by vendors](/details/wifi/wifi-by-vendors#wifi-access-point-charts) for information specific to each manufacturer.&#x20;

### Colour coding

When viewed for today only, each section on the Details page gives an indication if it is currently alerting and thus impacting the associated heat tile colour. Find out more about [colour coding](/details/details-page-options/colour-coding).&#x20;

### Channel Load description

Channel load charts show the utilisation of the WiFi channel (the percentage of time the channel is busy – either from other devices transmitting or interference). A vertical bar is drawn on the chart for each poll (typically every five minutes). As utilisation approaches the threshold, the vertical bar shows green through amber then red and maroon when the threshold is exceeded.

#### Threshold

The custom defined threshold is indicated with a thin horizontal purple line and shown in purple text in the right margin. The threshold value is 50% by default but can be altered by Admin users. See [WiFi Alerting Thresholds](https://support.highlight.net/help/admin/alerting_thresholds#wifi) for more information.\
If configured, an alert can be sent when channel load exceeds the threshold.

**Vertical axis:**  Scaling adjusts depending on data

**Threshold:**  If the adjusted vertical axis means the threshold line is not visible then a purple arrow is shown indicating the threshold is above the visible chart area.

**Horizontal axis:**  Adjusts according to the selected time period to show "hours" in day view and "days" in week and month views; redraws if the time zone is changed at the top right of the Details page

### Time period

Highlight displays the values for each data point in the time period:

<table data-view="cards"><thead><tr><th></th><th></th></tr></thead><tbody><tr><td>Day</td><td>Shows multiple data points per hour (one for each polling period, usually one to five minutes)</td></tr><tr><td>Week</td><td>Shows 24 data points per day (every hour), Maximum for each hour is shown</td></tr><tr><td>Month</td><td>Shows 6 data points per day (every 4 hours), Maximum for each 4 hour period is shown</td></tr></tbody></table>

For any time period, hover on a point to see date, timestamp, channel load and congestion as a percentage.

### Congestion

**Congestion** represents the number of retransmitted or failed frames expressed as a percentage of frames to be sent. The calculation is manufacturer dependent and based on the statistics available from the WiFi devices. Congestion is not calculated unless traffic volumes are more than one frame per second. Colours on the congestion line are:

<table data-view="cards"><thead><tr><th></th><th></th></tr></thead><tbody><tr><td><strong>Green</strong></td><td>Values are at or below the threshold</td></tr><tr><td><strong>Red blips</strong></td><td>Values exceed the threshold</td></tr><tr><td><strong>Grey</strong></td><td>No samples or congestion of 0%</td></tr></tbody></table>

#### Threshold

The threshold for congestion is set to 12% by default and can be altered by Admin users. This indicates how congested the AP radio networks are and uses the percent of send attempts that require retransmissions as the metric. The custom threshold is shown in purple text in the right margin. See [WiFi Alerting Thresholds](https://support.highlight.net/help/admin/alerting_thresholds#wifi) for more information.\
If configured, an alert can be sent when congestion exceeds the threshold.

# SD-WAN Tunnels

### Overview

This page describes the graphics available for SD-WAN tunnels on the Details page.

For Fortinet, tunnels are aggregated into a single tunnel representation. Highlight is focused on showing a location talking to another destination location, so rather than showing the technical components, we represent the information in a way non-technical users understand - location to location.

### Colour coding

When viewed for today only, each section on the Details page gives an indication if it is currently alerting and thus impacting the associated heat tile colour. Find out more about [colour coding](/details/details-page-options/colour-coding).&#x20;

### Traffic Load

{% hint style="info" %}
&#x20;These settings will be remembered when you next log in:

* Whether the panel is collapsed or expanded
* The status of any toggles
  {% endhint %}

### Summary

The summary shows the total values, peak and 95th percentages for in and out during the selected time period

**Total:**  Shows the accumulated volume of traffic for the time period displayed, calculated by adding the volumes from the polled samples.

**Peak (Actual):**  The bits per second value reported is from the individual sample with the highest throughput for the time period displayed. It will be seen as the highest point on the chart. The Highlight peak therefore is the sample with the largest volume, divided by the number of seconds between samples (typically 180 or 60). .

**95th percentile:**  The highest recorded value during the time period ignoring the top 5%, read more about [the 95th percentile and why it's useful](/reporting/network-reports/output#id-95th-percentile-load)

**Last sample:**  Only shown for today, this is the last recorded value (the last good sample) for today with **?** shown if no data was received

### Line Availability

A purple background on the chart indicates a maintenance window. Tunnels in maintenance do not send alerts, change the colour of heat tiles nor decrement availability figures. See [background colours](/details/details-page-options/background-colours) for examples.

Similar to Highlight's Line Health Availability, coloured blips, with the meanings shown below, are drawn on the chart.

<table><thead><tr><th width="109">Blip Colour</th><th width="194">Issue</th><th width="329">Effect in Highlight</th><th>Included in Total outages?</th></tr></thead><tbody><tr><td>Red</td><td>Tunnel down</td><td>Stability previously decremented<br>(only red after contact re-established)</td><td>Yes</td></tr><tr><td>Blue</td><td>API call failure - recovered (patched from Mustard to Blue)</td><td>Stability previously decremented<br>(only blue after contact re-established)</td><td>Custom</td></tr><tr><td>Mustard</td><td>API call failure - ongoing</td><td>Decrements stability and turns watch amber/red</td><td>Custom</td></tr></tbody></table>

### Discontinued tunnels and performance tests

Previously discovered tunnels may disappear from the SD-WAN network temporarily or permanently. These are deleted from Highlight automatically after 31 days - [contact us](/getting-started/contact-us) to change this retention period. Discontinued tunnels are labelled on the Details page.

If a discontinued tunnel or test reappears on the SD-WAN network during the retention period, then these labels are removed and the item resumes collecting and displaying data.\
If a discontinued tunnel or test does not reappear and the retention period ends, then the item is deleted from Highlight.

### Zoom options

There are two methods to zoom in on charts: drag and click. Find out more about [zoom options.](/details/details-page-options/zoom-options)

### Background colours

Grey backgrounds indicate non-business hours and purple backgrounds indicate maintenance periods.  Find out more about [background colours](/details/details-page-options/background-colours).

### Data not returned by vendor

Vendors differ in what information they provide. Panels on the Details page may be permanently collapsed because no information is being returned by the controller and so there are no chart values to display.


# Controller Status

### Overview

A parent controller may have hundreds of associated subwatches in the form of uplinks, tunnels, performance tests, etc. To limit alert spam, Highlight offers the option to suppress alerts on subwatches if the parent controller is uncontactable. Previously, this meant no alerts were sent if the controller was down. The controller status watch was designed to resolve this issue.

All controllers have a controller status watch created automatically. Alerts configured as 'all watch types' will send stability alerts if the controller is down. Alternatively, a specific alert for controllers only can be created.

For a Controller Status watch, this section shows graphically the availability and health for the selected time period (day, week, month) and date.

# Switches

### Overview

If your switches are recognised by Highlight, you can enable LAN switch monitoring to get a fast, detailed picture of how they are performing - traffic levels, health issues, and outages on every port, presented in a simple clear format. You can designate specific ports as 'critical' (for example, server connections) and Highlight will alert if these ports have problems.

### Collecting Data

Highlight collects two types of data from the switch:

1. #### At every poll on every port (typically every 5 minutes)
   * **Stability - State changes**

     Highlight detects any state change, essentially checking if a port is down
   * **Load - Traffic levels**

     In and out, calculated as a percentage of port speed with 80% as the threshold value
   * **Health - Error frequency**

     Reported as errors per 1000 packets. What constitutes an error varies by vendor but usually is a mix of low-level errors (framing, duplex, bad-sized packets etc.) and Layer 2 errors (CRC checks). For more information consult the individual vendor documentation. Errors are normally caused by faulty cabling or a faulty switch port.
2. #### Once an hour on every port

   Highlight collects the following every hour to update basic data on the switch:

   * Port Name: as configured on the switch as the description
   * Port State: up or down and the length of time it has been up or down
   * Port Speed: normally 10M / 100M / 1G bps

   This information is used on the Technical Details page and pop-up, see section below.

{% hint style="info" %}
**Update interval**\
This information is not real-time and so will only update in the UI at the same interval as data is collected, i.e. per hour.
{% endhint %}

{% hint style="info" %}
**Data Retention**\
By default, switch data for display on the Details page is retained for 3 months.
{% endhint %}

### Slot Summary

See [the Switch Slots page.](/details/other-watch-types/switch-slots)

### Port Summary

{% hint style="info" icon="eyes" %}
Find out which slots are running low on available ports by running a [Switch Port Capacity report.](/reporting/network-reports/suggested-reports#switch-port-capacity-report)
{% endhint %}

The upper part of the Details page shows a summary of every port on the switch. For all time periods (day, week or month) the summary shows:

* any issues as stability, load or health
* the severity or frequency of any issues

<figure><picture><source srcset="/files/i9yeXKU8lyNLNqdZueYO" media="(prefers-color-scheme: dark)"><img src="/files/9rjQa4trD2uc7xxmHp2P" alt="Switch Port Summary"></picture><figcaption></figcaption></figure>

#### Today: Live Status

When **Today** is selected a live status is shown as a coloured square behind the port number. This status is obtained by the poller every 5 minutes. The colours mean:

Green: the port is live

Amber: the live status is unavailable due to issues obtaining details; all ports will show as amber

Red: critical port is down, red is only used for critical ports

Grey:  non-critical port is down, idle or unused, grey is only used for non-critical ports

White circle:  indicates a port that was idle, unused or down throughout the selected time period - a useful way to spot ‘free’ ports on a switch

Green circle:  indicates an active port; the marker will remain green for each metric (stability, load, health) unless certain conditions occur, further details below

***

#### Stability:

{% hint style="info" %}
Stability is only shown on critical ports. Non-critical ports may be inactive for long periods so stability is not a relevant metric.
{% endhint %}

Amber circle:  For each poll within the selected time period, Highlight detects any state change, essentially checking if a port is down.

Red circle:  indicates port was down for at least one sample in the time period indicates port was down for 10% or more of samples in the period

#### Load:

Amber circle:  For each poll within the selected time period, Highlight detects load greater than the threshold value and then counts how many instances of excessive load occur. The threshold is 80%.

Red circle:  indicates port load was > threshold on 5% - 50% of the samples in the time periodindicates port load was > threshold on 50% or more of the samples in the time period

#### Health:

Amber circle:  For each poll within the selected time period, Highlight detects any errors.

Red circle:  indicates port error rate was >0 for 0.5% - 5% of the samples in the time periodindicates port error rate was >0 for 5% or more of the samples in the time period

**Special case**

If all samples for a port return **Port down** for the period requested, then Stability, Load and Health all display as white

**Alias or interface name**

Hovering over an individual port will show a tooltip with that port’s alias or interface name, if one has been configured on the switch; otherwise the tooltip will show the interface name. If neither the alias nor the interface is available, the port number is shown.

**Critical ports**

Clicking on an individual critical port will scroll to and expand a chart for that port for the selected time period. Each chart is labelled with the slot and port number,and alias or interface name, if available.

### Port Summary Filter on All/Active/Critical

<figure><picture><source srcset="/files/trWldhVRRRIM6WU9EEJg" media="(prefers-color-scheme: dark)"><img src="/files/JL847IUIw2BiPqmquRNc" alt="Switch port filters: All, Active and Crticial GIF"></picture><figcaption><p>Switch port filters: All, Active and Crticial GIF</p></figcaption></figure>

**All:**  This is the default option. All ports are shown.

**Active:**  This includes active and critical ports.\
Active means the port had data within the selected time period (day, week or month).

**Critical:**  Only ports which have been designated as critical are shown.

{% hint style="info" %}
&#x20;The filter setting will be remembered when you next log in.
{% endhint %}

### Technical Details

Clicking the Tech info on the Details page shows the information Highlight has on this switch. As outlined in the collecting data from the switch section above, Highlight collects this information on an hourly basis to reduce management traffic overhead. The date / time of the last collection for this switch as **Last Checked** in the list.&#x20;

In [Admin, Edit Watch, on the Features tab for the switch,](https://support.highlight.net/help/admin/switches) use Set Critical Port&#x20;

#### Port information

For switches, a summary for each slot is shown with the total number of ports and how many are idle and unused. Then each port on the device is listed with the following information:

**Critical:**  whether this port is marked as critical in Highlight, meaning it will affect heat tiles and generate alerts

**Slot:**  a number

**Port:**  a number

**Interface:**  the name used on the device to reference that port

**Alias:**  the description configured on the interface, if any

**Speed:**  the current speed of this port; some switches return ‘Unknown’ if the port is not in use

**State:**  state of the port and the length of time it has been in this state. The description of port states are as follows:

**Up:**  port is active

**Down:**  changed state from Up in the last 48 hours

**Unused:**  most recent state changed within 10 minutes of system power up

**Idle:**  a previously used port that has been inactive for over 48 hours

### Critical Ports

<figure><picture><source srcset="/files/xem87mZQVrrvFamdMi5k" media="(prefers-color-scheme: dark)"><img src="/files/na8fCql85BTZBLPn70Ai" alt="Switch Critical Port Chart"></picture><figcaption></figcaption></figure>

For the switch, this panel shows a chart for each critical port designated in Highlight. Only critical ports can change the colour of a heat tile and generate an alert email or webhook. Charts are labelled with the slot and port number and that port’s alias or interface name, if one has been configured on the switch. Critical ports are also indicated by a blue background marker in the Port Summary panel.

{% hint style="danger" %}
A port that is disabled behaves the same as if the port is down (red blips etc.)
{% endhint %}

***

#### Stability

**Stability** blip line is shown as a grey line if unavailable or a thicker green line if up. Hover on the chart to see timestamp and precise values.

| Colour    | Grey line | Green line     | Red blip  |
| --------- | --------- | -------------- | --------- |
| Stability | No data   | Receiving data | Port down |

***

#### Load

**Load** has two blip lines for in and out. A grey line is shown if unavailable or a thicker green line up to 50%. Hover on the chart to see timestamp and precise values. Above 50% it's shown in coloured blips:

<table><thead><tr><th width="81">Colour</th><th width="91">Grey line</th><th width="111">Green line</th><th width="113">Green</th><th width="119">Amber</th><th width="116">Orange</th><th>Red</th></tr></thead><tbody><tr><td>Load</td><td>No data</td><td>0% to 50%</td><td>51% to 65%</td><td>66% to 80%</td><td>81% to 95%</td><td>96% to 100%</td></tr></tbody></table>

***

#### Health

**Health** blip line shows coloured blips according to the severity of the line drops and errors detected on the port. Hover on the chart to see timestamp and precise values. Coloured blips indicate approximate values:

<table><thead><tr><th width="87">Colour</th><th width="86">Grey line</th><th width="89">Green line</th><th width="72">Green</th><th width="108">Amber Green</th><th width="80">Amber</th><th width="88">Orange</th><th width="85">Red</th><th>Maroon</th></tr></thead><tbody><tr><td>Health</td><td>No data</td><td>0</td><td>1</td><td>2 - 11</td><td>12 - 23</td><td>24 - 52</td><td>53 - 74</td><td>75 - 100</td></tr></tbody></table>

#### Related information

With admin privileges see how you [enable critical ports](https://support.highlight.net/help/admin/switches)

See next section for how critical ports affect heat tiles and generate alerts.

### How critical ports affect heat tiles and generate alerts

Only switch ports selected as critical can change heat tiles and generate alerts. If you have admin privileges you can [enable a port as critical](https://support.highlight.net/help/admin/switches) by using Set Critical Port  [in Admin, Edit Watch, on the Features tab for the switch](https://support.highlight.net/help/admin/switches) or via the [Controllers Admin page, Edit watch, Critical Ports tab](https://support.highlight.net/help/admin/sdwan_items#edit_watch_critical_ports_tab).

#### Sensitivity settings

Heat tiles and alerts are controlled by sensitivity settings which are configurable by admin users with the permission **Manage folders/locations**. Find out more about [the sensitivity of heat tiles](https://support.highlight.net/help/admin/heat_tiles_sensitivity). For the example here, we assume the following settings:

<figure><picture><source srcset="/files/bmuZdGh9lmwqOAIr0wWR" media="(prefers-color-scheme: dark)"><img src="/files/Gl9nXgSMhbmkGgrmbe5s" alt="Ssensitivity settings"></picture><figcaption><p>Sensitivity settings for the example below</p></figcaption></figure>

#### Thresholds

The tables below show how each metric changes a heat tile and generates an alert (if one has been set up) based on the sensitivity settings in the previous image.

Table below shows turning from green to amber and eventually red:

<table><thead><tr><th width="96">Metric</th><th>Example condition for bad sample</th><th>Samples to turn from green to amber</th><th>Samples to red</th></tr></thead><tbody><tr><td>Stability</td><td>Port is down</td><td>2</td><td>2 more; 4 in total</td></tr><tr><td>Load</td><td>>60%</td><td>5</td><td>5 more; 10 in total</td></tr><tr><td>Health</td><td>Errors per 1000 frames rate >1;</td><td>10</td><td>10 more; 20 in total</td></tr></tbody></table>

Table below shows returning back from red to amber and eventually green:

<table><thead><tr><th width="98">Metric</th><th>Example condition for good sample</th><th>Samples to turn from red to amber</th><th>Samples to green</th></tr></thead><tbody><tr><td>Stability</td><td>Port is up</td><td>3</td><td>3 more; 6 in total</td></tr><tr><td>Load</td><td>≤60%</td><td>6</td><td>6 more; 12 in total</td></tr><tr><td>Health</td><td>Errors per 1000 frames rate ≤1</td><td>12</td><td>12 more; 24 in total</td></tr></tbody></table>
