Flow Reports
TCP implements flow control at the transport layer, where the transmission and receipt of data
packets is coordinated. Reconnex taps that activity to display a real-time snapshot of current flows.
Using the Flow Reports can help to identify heavy users of network resources. For example, you
may discover that some flows are processed by several different hosts. After examining these
patterns, you may want to consider memory management.
You can get a sampling of these flow reports at System > System Administration > Advanced >
Utilities > Counters.They are produced by SQL commands that are triggered when you click on
the Advanced link.

The Flow Reports are found at System > System Administration > Advanced > Utilities >
