Flow: 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 ( or) 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.
- . Displays the application used by the devices generating the highest traffic on the selected interface.
: 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) to view all unclassified traffic since the last hourly rollup.
- . Displays the bytes per second for the report category.
- . Displays the percentage of the total available bandwidth used by the report category.
: Usage is displayed as N/A if a speed is not specified for the interface. You can set this speed on the Flow Interface dialog. To navigate to the Flow Interface dialog, right-click on the interface on which you want to set the speed, then click .
- . Displays the percentage ranking of the item within the top "n" items of the report category.

: For illustration purposes, the descriptions and diagrams in the table below assume that traffic is passing from an internal interface to an external interface or vice versa. In reality, traffic may pass from an internal interface to another internal interface, an external interface to another external interface, or traffic may be routed out the same interface it enters.

- Linking to Flow Monitor reports from WhatsUp Gold
There are several ways to connect to the Flow Monitor Interface Details report from this WhatsUp Gold workspace report.
- Click the interface name at the top of the workspace report to view the Flow Monitor Interface Details report for the selected interface.
- Click an entry in the far left column of the workspace report to view the Interface Details report for the selected interface. The entry that you click will be applied to the report as a keyword filter.
- Configuring this workspace report
- In the title bar of the workspace report pane, select . The Configure Report dialog appears.
- Enter or select the appropriate information in the following fields.
- . Enter a title for the workspace report. This name appears in the title bar of the workspace report's pane.
- . Select the timeframe for the traffic about which you want to see a report. You can select either the last 5, 15, or 30 minutes, or the last hour.
- . Select the router interface that is used by the traffic you want to see in this report.
- . Select a direction for which the report will display data for the selected interface (In, Out, or Both).
- . Enter the number of records you would like displayed in the workspace report.
- . Select the type of data you would like displayed within the workspace report (Chart and data, Data only, Chart only).
- . Select the type of chart you would like the report to display.
- . Specify how wide, in pixels, the graph or chart should appear.
- . Specify how tall, in pixels, the graph or chart should appear.
- . Click this button to apply a filter by which report data will sort. After clicking, filter fields appear below the button.
Select the type of filter you want to apply. If appropriate, select a secondary filter type from the second filter field. For more information on filters, see Filtering Flow Monitor workspace reports in WhatsUp Gold.
