Use the Flows window to view and analyze traffic at a very detailed level. InterMapper Flows acts as a NetFlow/sFlow collector; the Flows window provides a view of Flows data collected from supported hardware and software exporters.
To open the Flows window:
Use the Flows window to view Flows data in a number of ways.
When you first open the Flows window, the Hosts tab is selected.
Click a tab to choose one of these Flows window pages:
When collecting data from both NetFlow and sFlow exporters, you can tell at a glance what kind of exporter the data is coming from.

J-Flow, CFlow |
These exporters implement a Flows format that is identical to NetFlow v5, so they appear as NetFlow v5 in the Flows window. |
Use the filter tools to view a subset of the data, selecting from available exporters, talkers, listeners, ports or sessions collected by InterMapper Flows.
