Top Interfaces by Utilization report reveals a ranked list of network interfaces showing the highest percentages of capacity utilization for the selected interval. Ranked items display in order of maximum utilization (incoming and outgoing).

Note: The same bytes can be counted twice where a byte total is noted arriving from a sender and the same bytes are counted when relayed to the receiver.

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. Number of bytes received.
  • Incoming Rate. Total average rate of inbound traffic.
  • Incoming
    • Utilization. Fraction of total bandwidth capacity used. "N/A" denotes the measurement cannot be calculated because the bandwidth capability is unknown for the current interface.
  • Outgoing Bytes. Number of bytes transmitted from the interface.
  • Outgoing Rate. Total average rate of outbound traffic.
  • Outgoing Utilization. Fraction of bandwidth capacity used.
