NetFlow: 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. Applications correspond to ports that are used by IP protocols (80:http, 110:pop3, 443:https, etc.). By default, NetFlow Monitor monitors ports below 1023, and a few higher numbered ports. You can configure monitored ports on the NetFlow Ports dialog.

Application data is useful in determining the types of tasks persons on the network are conducting the most over the selected time period. For example, pop3 indicates a person is checking email, while http signifies other Web-based tasks.

Application traffic is reported in bytes and as a percentage of the top x results from the current interface for the selected time period.

• About interface traffic directions

  Note: 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.

  Interface	Traffic Direction	Report displays...
  Internal interface	Inbound	The top applications used by devices on the LAN segment connected to the selected internal interface to communicate with outside devices.
  	Outbound	The top applications used by outside devices to communicate with devices on the LAN segment connected to the selected internal interface.
  	Inbound/ Outbound	The top applications used by all devices transmitting traffic across the selected internal interface.
  External interface	Inbound	The top applications used by devices connected to the selected external interface to communicate with devices on an internal LAN segment.
  	Outbound	The top applications used by devices on internal LAN segments to communicate with devices connected to the selected external interface.
  	Inbound/ Outbound	The top applications used by all devices transmitting traffic across the selected external interface.

• Linking to NetFlow Monitor reports from WhatsUp Gold

  There are several ways to connect to the NetFlow Monitor Interface Details report from this WhatsUp Gold workspace report.

  • Click the interface name at the top of the workspace report to view the NetFlow 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
  1. In the title bar of the workspace report pane, select Menu > Configure. The Configure Report dialog appears.
  2. Enter or select the appropriate information in the following fields.
     • Report name. Enter a title for the workspace report. This name appears in the title bar of the workspace report's pane.
     • Date range. 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.
     • Interface. Select the router interface that is used by the traffic you want to see in this report.
     • Interface traffic direction. Select a direction for which the report will display data for the selected interface (In, Out, or Both).
     • Maximum rows to return. Enter the number of records you would like displayed in the workspace report.
     • Display. Select the type of data you would like displayed within the workspace report (Chart and data, Data only, Chart only).
     • Chart type. Select the type of chart you would like the report to display.
     • Width. Specify how wide, in pixels, the graph or chart should appear.
     • Height. Specify how tall, in pixels, the graph or chart should appear.
     • Filter. 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 NetFlow Monitor workspace reports in WhatsUp Gold.

       Note: Filters applied here are listed at the top of the workspace report in Current filters.
