Top Senders
This workspace report shows the devices generating the most traffic traveling in the selected direction (Inbound, Outbound, Inbound and Outbound, or Bounce) on the selected interface.
By default, sender 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 sort traffic by bytes, packets, or flows. By default the report sorts by bytes and provides a list of the top senders by number of bytes. Sorting by packets provides information on the top senders by number of packets, while sorting by flows provides insight into the top senders by number of flows. These alternate sorting methods allow you to monitor and identify hosts that are the largest consumers of interface resources other than bandwidth.
: You can hover over a host name to display popup information about the host name's IP address.
: You can hover over information in the column to display popup information with average data speed as a percentage of the total interface capacity.
: You can hover over the icon preceding the Senders host name to display WHOIS information about the host. This information is gathered using a WHOIS query of the American Registry for Internet Numbers (ARIN).

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.
