Tunnel
Main
Use this panel to edit a tunnel. If the parent controller has the option to autodiscover tunnels selected, then Highlight discovers tunnels. Tunnels cannot be created any other way.
Discovered
Read-only and shows the date of autodiscovery of the tunnel.
Name
Read-only and shows the autodiscovered name which is the "from" device Network ID to the "to" device Network ID plus the Highlight unique identifier for the "from" device.
Description
Auto-generated using the "from" location - To - the "to" location. This cannot be changed in this dialog and appears throughout Highlight instead of the name.
Enable
By default, all four options are checked:
Collect data — Uncheck to turn off polling, which keeps the tunnel in the system and can appear in Highlight statistical reports, but stops data being collected from the device so no alerts will be raised. Used for displaying history of an old tunnel, for example.
Show data — Uncheck to turn off display of the tunnel in the UI and in any Highlight statistical reports, although data can still be collected. If this is unchecked then the watch will not appear in the tree search, only the admin search.
Send alerts — Uncheck to turn off alerting for the tunnel. Data will continue to affect heat tiles (when thresholds are crossed) but no alerts will be generated. Used for testing and demonstration, for example.
Generate statistical reports — Uncheck to turn off gathering of statistics for Network Reporting although data will still be collected.
FROM / TO
Location — where the device is in Highlight
Device — a link to the device description (if available) otherwise the name
Product Type
Read-only text set to Tunnel and appears on watch status cards.
Reference
Optional and can contain a maximum of 50 characters. May be useful for customer specific information, see the Inherited Reference section for more details.
One save stores details for all tabs.
If the parent device has been deleted on the external network, a red warning bar is shown reading "Parent device no longer exists." See Discontinued items.
Discontinued tunnels
See Discontinued items. Discontinued tunnels are labelled in the following ways:
The tunnel row is faded red with a warning triangle under Status
A red bar is shown on the Edit Tunnel panel
A red bar shows across the top of the tunnel Details page
Performance
This tab is visible on any tunnel. If Tunnels with perf tests has been selected on the parent controller then Highlight automatically discovers and creates tunnels and any performance tests as subwatches of their parent tunnel.
If the controller option is changed to None after tunnels and performance tests have been discovered, these will continue to work and can be manually disabled if needed. No new tunnels or tests will be discovered.
If there are no tests or the option is to Tunnels, you will see the message "No performance tests have been discovered. Please check performance test autodiscovery is enabled on the parent controller."
Type
Shows the performance test icon and the test type.
Status
Enabled or Disabled. Disabling a test means:
no data is collected for the test
alerts cannot be sent nor colours changed (green to amber for example)
the watch status card disappears for the test
the performance chart (on the details page) disappears for the test
Details
Name — Read-only and comprised of [Source interface] [Source device description (if available, otherwise the device name)] to [Target interface] [Target device description (if available, otherwise the device name)]
Discovered — Read-only and shows the date of autodiscovery of the test.
Alerting thresholds
The default setting for these values are set on a folder, inherited by all subfolders and used on the initial creation of tests only. Contact us to change defaults. Highlight compares the value reported by the external network to the threshold set here to determine if the fuel gauge should be incremented or decremented. Delay, packet loss and score impact Health and 100% packet loss impacts Stability. Read more about the Highlight Alerting Mechanism.
Delay — Also known as latency or round trip delay, test results are compared to this threshold.
Jitter — Value reported by the external network is compared to this jitter threshold to colour the chart on the Details page but Highlight does not alert on jitter.
Pkt loss — Packet loss is expressed as a percentage of all packets sent and compared to this threshold.
Score — If available for the test type, the Mean Opinion Score (MOS) on the scale of 1-5 with 5 indicating excellent quality and compared to this threshold. Otherwise, if not available, this field is disabled.
