Top Endpoint Groups
Top Endpoint Groups report reveals the top endpoint groups that are sending and receiving the most traffic for the selected interval.
: 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.
- . Top endpoint group name. Other indicates traffic not associated with a group.
- . Combined (incoming/outgoing) number of bytes transferred. (Use Report Settings
option to rank the list by packet or flow count, not bytes.) Red (
) indicates fraction received. Blue (
) indicates fraction sent. (Mouse hover to display in/out summary.) - . Average bit rate, in total bits per second (bps).
- . Percentage of the total traffic.
To display Flow and Packet measurements, click a column heading (
) for column selection list (
). You can also include:
- . Fraction of total bandwidth capacity used. "N/A" denotes the measurement cannot be calculated because the bandwidth capability is unknown for the current interface.

- The rate of bits transmitted in the interface for the selected date range.
- . The rate of bits transmitted out of the interface for the selected date range.
- . The number of flows transmitted in the interface during the selected date range.
- . The number of flows transmitted out of the interface during the selected date range.
- . The total number of flows for the interface during the selected date range.
- . The rate of flows transmitted in the interface during the selected date range.
- . The rate of flows transmitted out of the interface during the selected date range.
- . The average flow rate, in multiples of flows per second (fps) for the selected date range.
- . The number of packets transmitted in the interface for the selected date range.
- . The number of packets transmitted out of the interface for the selected date range.
- . The total number of packets for the specific item in the report category for the selected date range.
- . The rate of packets transmitted in the interface for the selected date range.
- . The rate of packets transmitted out of the interface for the selected date range.
- . Displays the average packet rate, in packets per second (pps), for the selected date range.
