TheInterface Usage report reveals Network Traffic Analysis source, incoming and outgoing interface traffic totals (and trends) for the selected period. Interfaces can be displayed separately, or grouped together by name. If you group by interface name, all interfaces under a single display name are summed, and all data displayed is a total for those interfaces.

Understand column data

The default view of each report contains a grid with the following columns:

  • Interface. Device hostname, IP address, or custom label.
  • Incoming Bytes. Traffic volume received on the interface.
  • Incoming Rate. Total average rate of inbound traffic.
  • Incoming 95th Percentile. Usage is at or below this figure 95% of the time. (Raw data calculation.)
  • Outgoing Bytes. Total bytes transmitted from the interface.
  • Outgoing Rate. Total average rate of outbound traffic.
  • Outgoing 95th Percentile. Usage is at or below this figure 95% of the time. (Raw data calculation.)
