The Top Users dashboard provides an overview of the most active entities
and protocols in the network traffic. All sections can be minimized or maximized
by click on the arrow next to a section.

A history graph shows the receive bitrate for each active interface.
A history graph shows the receive bitrate for each active interface.
The table next to the history graph contains the link status for each active
interface including the active link speed, the current receive bitrate, the
link utilization and a button that allows to capture the traffic of that
particular interface. If a NIC filter has been configured, the filtered amount
of traffic is shown in the last row of the table.
