H.323 Protocol Performance
This section describes the different statistics you can access for monitoring H.323 protocol performance.
Viewing the H.323 Performance Statistics
Display the H.323 performance statistics by using the show h323d command. The main show h323d command executed without arguments indicates the date and time the current period began and displays session statistics, status statistics, and stack statistics for functioning H.323 processes.
For example:
acmepacket# show h323d
18:22:24-84

Viewing Session Agent Group Stats
You can view statistics for session agent groups.
Viewing Session Agent Group Stats
Display session information for the session agent groups by using the show h323d groupstats command. Session information is compiled by totalling the session agent statistics for all session agents that make up a particular session agent group.
While the show h323d groupstats command accesses the subcommands that are described in this section, the main show h323d groupstats command (when executed without arguments) displays a list of all session agent groups for the Oracle Communications Session Border Controller.
All of the categories for these statistics are the same as those used in the displays produced by the show h323d agent command.

You can list and show the statistics for the session agents that make up the session agent groups that are being reported. The -v (meaning verbose) executed with this command must be included to provide this level of detail.
