Configuring Profiler Database Preferences (NSM Procedure)

ScreenOS 6.2 supports application volume tracking (AVT), a feature that enables NSM to track network bandwidth usage on a per-application basis. The security device sends the NSM server periodic update messages containing details about port activity. NSM listens and processes these periodic update messages and maintains a cumulative count for each port. NSM displays this count on the console. NSM provides reports about application volume tracking. The AVT feature has the following limitations:

For more details on AVT, see the Network and Security Manager Administration Guide.

Use the Profiler Settings under the Tools menu to configure the Profiler preferences mentioned in Table 12. You can use the Profiler Settings dialog box to modify Profiler database settings and default settings for application volume tracking reports.

Data discovered by Profiler is stored in a database located on the NSM GUI server.

To modify profiler database preferences and application volume tracking settings:

  1. From the NSM main menu, select Tools > Preferences. The New Preferences dialog box is displayed.
  2. Click Profiler Settings.
  3. Modify settings as described in Table 12.
  4. Click OK.
