Advanced - persistent TCP sessions

You can include persistent TCP sessions in the TCP statistics and tune their monitoring if such an inclusion is required for comprehensive TCP reporting.

Persistent TCP sessions are TCP sessions for which the start was not recorded. They are also referred to as non-SYN sessions. These sessions can be included in the TCP statistics, based on the configuration properties you enable in the NAM Console. The inclusion of these sessions may render the statistics somewhat inaccurate and must be undertaken with care.

The following configuration options are provided in the NAM Console when you access NAM Probe Configuration :

  • Monitor and report persistent TCP sessions for default software services
    Go to Global  ► Advanced  ► Persistent TCP Sessions and select the Enable monitoring for default software services check box to enable monitoring and reporting the persistent TCP sessions for well-known ports. Clear the check box to disable this functionality.
    This feature is turned off by default.
  • Monitor and report persistent TCP sessions for unknown ports
    Go to Global  ► Advanced  ► Persistent TCP Sessions and select the Enable monitoring for unknown ports check box to enable monitoring and reporting persistent TCP sessions for unknown ports. Clear the check box to disable this functionality.
