These can be viewed monthly, weekly or daily, including real-time updates within the Highlight Portal. In the example below the traffic volumes entering the Steelhead on the LAN side is 826GB whereas the traffic leaving the device on the WAN side is 406GB. Therefore there has been about 51% compression in transmitted data from this site. ## Application Visibility Highlight Flow provides visibility of top 20 Applications running on the network, and top 20 Sources and Destinations of traffic. Users can pick any of these top applications or hosts, and expand it with a click to see the top 10 conversations making up that traffic flow. Drill‐downs allow users to understand traffic patterns and spot and report on trends and anomalies. Depending on the Operating system release, Steelhead appliances support NetFlow versions 5 or 9. The Highlight supported set-up to measure data from client to server is to monitor the LAN interface on the client-side Steelhead appliance; this will export the raw, pre-optimized traffic.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://help.highlight.net/functionality/riverbed-steelhead-monitoring.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
