Top Sources with Interfaces reveals interface metrics grouped by the flow source that exports them.

Identifying data transfer rate and capacity utilization from specific points on your network enables you to:

  • Identify packet choke points by checking where send or receive utilization is close to capacity.
  • Plan scaling and build out periods. Track high traffic routes over time.
  • Sanity check load balancing and track ToS-specific policies applied at routers.
  • Localize disruptive traffic to a specific router or interface.
  • Drill down into specific flow sources and configuration properties () of a particular network interface.
  • Be proactive.

Understand column data

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

  • Interface. Device hostname, IP address, or custom label grouped by Source with Ethernet port index. Index of 0 denotes the NULL interface.
  • 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. Total bytes transmitted from the interface.
  • Outgoing Rate. Total average rate of outbound traffic.

To display Flow and Packet measurements, click a column heading ( ) for column selection list ( ). You can also include:

  • Source Name. Device hostname, IP address, or custom label.
  • Interface Name. Textual name of the interface (ifName).
  • SNMP Index. Network interface SNMP table identifier (ifIndex).
  • In Speed. Inbound hardware speed.
  • Out Speed. Outbound hardware speed.
    Tip: To show reports in full screen with most if not all possible columns, click on report options menu and choose Expand.

Generate a report
