This default welcome screen shows summary server flow information with three main sections:

Summary Devices

This is a summary of traffic across all of your infrastructure devices ranked by the busiest network device. Infrastructure devices are routers sending flow as well as other Layer-2 devices that are not sending flow but sending ARP and CAM Tables. The information displayed includes:

  • Avg Bits/s: average traffic per second.
  • Max: this is maximum traffic volume seen in the data set.
  • Percentage: this is the proportion of all traffic seen by particular system/router.

The bars on the graph indicate the volume of data seen over the reporting period, by default 2 hours.

Summary Interfaces

This is a graph and table of interface bit rates, with a breakdown by individual interface. This is a summary of the busiest interfaces across your network.

See Configuration > Infrastructure Devices for setup instructions.

When more than 10 devices are registered, the full list can be displayed by clicking List All Drill down icon. beside the table title.

The CSV link at the top right of the table generates a .csv export.
