NFA 9.3.2 introduces a New Flow Statistics page which will allow you to view flow rates for all of your Harvesters on one page.
This replaces some of the functionality from the NFAParser/NASTv13 tool, and adds some new functionality that was not available in the NAST tool.
The Admin->Flow Statistics page displays Flows Per Minute rates of all of your Harvesters together, but also lets you filter down to a specific Harvester, router or interface.
It also displays the number of routers and interfaces on each Harvester, along with statistics and reasons for Dropped Flows.
