Top Applications

This workspace report displays the applications used by devices generating the most traffic traveling in the selected direction (Inbound, Outbound, Inbound and Outbound, or Bounce) on the selected interface. Application definitions are created using the Map Ports to Applications dialog (GO > Configure > Applications > New or Edit) which maps port numbers to applications.

Application data is useful in determining the types of tasks persons on the network are conducting the most over the selected time period.

Note: Traffic that flows between unmonitored ports is considered unclassified. In Flow Monitor, for traffic to be considered "unclassified," both the port from which the data is sent, and the receiving port must not be mapped to an application in the Configure Application dialog. If either the sending or receiving port is mapped to an application, the traffic is associated with the application.

If Flow Monitor detects a large amount of traffic to an unmonitored port, this workspace report displays a yellow warning flag that explains the situation and guides you in defining the unmonitored port. This can help you to proactively detect emerging non-standard traffic on your network. You can also use the Unclassified Traffic dialog (available from any page in Flow Monitor by selecting GO > Configure > Flow Unclassified Traffic) to view all unclassified traffic since the last hourly rollup.

Percent of Top n. Displays the percentage ranking of the item within the top "n" items of the report category.
