+ | * searching individual flows for a particular User or App at flow level | ||
+ | * aggregate statistics of a particular User or App. | ||
+ | |||
+ | ===== Monitor overall traffic ===== | ||
+ | |||
+ | ==== New Counter Groups : User-ID and App-ID | ||
+ | |||
+ | Trisul automatically creates two counter groups called User-ID and App-ID. These meter the following metrics at the global level. | ||
+ | |||
+ | ^meter^description^ | ||
+ | |Total traffic|Total traffic bandwidth used by a User or App| | ||
+ | |Download traffic| Download bandwidth used by per User/App. The Download direction is metered when the flow source IP is an external IP address and the destination-IP is internal. Internal IPs belong to the Home Network configured in Trisul| | ||
+ | |Upload traffic| per-User bandwidth out of home network to external| | ||
+ | |Internal traffic| per-User bandwidth where both the source and destination are inside the home network| | ||
+ | |Transit traffic| where both source and destination are outside the home network. You will typically not find data here in normal enterprise environments| | ||
+ | |Flows| Total number of flows active per user/app | | ||
+ | |||
+ | |||
+ | To view these metrics | ||
+ | * **Use Retro Analysis** : Select //Retro > Retro Counters// then select a time frame, then select User-ID from the list of counters shown on the right side. You can see the top items for each metric. | ||
+ | * **Create dashboards** : Customize > UI > | ||
+ | |||
+ | The retro analysis screen looks like below. | ||
+ | |||
+ | {{: | ||
+ | |||
+ | The Retro Analysis tools show you the Top-N, Bottom-N, Topper Trend over time, and Pie chart views. The following chart shows you toppers over time. | ||
+ | |||
+ | {{: | ||
+ | |||
+ | |||
+ | ==== NAT issues ==== | ||
+ | |||
+ | The default behaviour is to show the Internal and External IP addresses. The NAT is hidden from Trisul , if you wish to see the NAT'd firewall address set the following parameter to FALSE in the [[https:// | ||
+ | |||
+ | < | ||
+ | < | ||
+ | |||
+ | </ | ||
+ | |||
+ | |||
+ | ==== Query by user-id and app-id ==== | ||
+ | |||
+ | The next step is to create a [[https:// | ||
+ | |||
+ | Login as admin, then go to profile0 > Flow Taggers > Create a new Flow Tagger. | ||
+ | |||
+ | {{: | ||
+ | |||
+ | Do the same for App-ID. | ||
+ | |||
+ | === Query flows === | ||
+ | |||
+ | |||
+ | //From Tools > Explore Flows// | ||
+ | Use the syntax '' | ||
+ | or '' | ||
+ | |||
+ | You can see the flow tags. | ||
+ | {{: | ||
+ | |||
+ | |||
+ | |||
+ | === Aggregate flows === | ||
+ | |||
+ | //From Tools > Aggregate Flows// | ||
+ | Use '' | ||
+ | |||
+ | This shows top IPs, top Applications, | ||
+ | |||
+ | A sample is shown below. | ||

+ | |||
+ | ==== Conclusion ==== | ||
+ | |||
+ | User-ID and App-ID attributes open up very powerful possibilities for visibility and investigation. Using the flexible tools offered by the Trisul platform you can customize in a variety of ways. Other tools you can use are " | ||
