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 8-6 About Flow Statistics If you enable flow counters, you can enable a maximum of 1 K 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. Generation 1 modules allow a maximum of 1024 flow statements per module. Generation 2 modules allow a maximum of 2048-128 flow statements per module. Table 8-1 explains the Flow Type radio button that defines the type of traffic monitored.
