Top Interfaces by Utilization

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.

Interface. Device hostname, IP address, or custom label.
Incoming Bytes. Number of bytes received. (Use Report Settings Sort by option to rank the list by packet or flow count, not bytes.)
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.
