Flow Statistics Configuration
Flow statistics count the ingress traffic in the aggregated statistics table. You can collect two kinds of
statistics:
• Aggregated flow statistics to count the traffic for a VSAN.
• Flow statistics to count the traffic for a source and destination ID pair in a VSAN.
This section includes the following topics:
• About Flow Statistics, page 29-4
• Counting Flow Statistics, page 29-4
About Flow Statistics
If you enable flow counters, you can enable a maximum of 1024 entries for aggregate flow and flow
statistics. Be sure to assign an unused flow index to a module for each new flow. Flow indexes can be
repeated across modules. The number space for flow index is shared between the aggregate flow
statistics and the flow statistics.
Table 29-1 explains the Flow Type radio button that defines the type of traffic monitored.
Counting Flow Statistics
To count the flow statistics for an active zone set using Fabric Manager, perform this task:
Step 1 Expand End Devices, and then choose Flow Statistics in the Physical Attributes pane.
You see the Flow Statistics as shown in Figure 29-2.
