The Network Flows Layer

The tests mapped to this layer read the aggregated netflow statistics that the collector stores in the binary files, groups these statistics by network interface, and for each interface, reports the network traffic and bandwidth usage of:

• Top-N sources
• Top-N destinations
• Top-N conversations
• Top-N applications/protocols

You can also optionally configure this layer to report on the network activity of key sites and specific sources/destinations.
