NetFlow: Top Sender Groups
This workspace report shows the sender groups generating the most traffic traveling in the selected direction (Inbound, Outbound, Inbound and Outbound, or Bounce) on the selected interface. Sending Group data is useful in determining which groups on the network are using the most bandwidth by sending the most information.
Groups are user defined sets of hosts that allow customized reporting and are configured via the NetFlow Groups dialog. You can access this dialog from anywhere in the web interface by selecting . When the GO menu appears, on the section of the menu, select .
Sender group traffic is reported in bytes and as a percentage of the top x results from the current interface for the selected time period.
: You can hover over information in the column to display popup information with average data speed as a percentage of the total interface capacity.

About interface traffic directions
: For illustration purposes, the descriptions and diagrams in the table below assume that traffic is passing from an internal interface to an external interface or vice versa. In reality, traffic may pass from an internal interface to another internal interface, an external interface to another external interface, or traffic may be routed out the same interface it enters.
