The session manager interface enables complete statistics for all sessions established through a session manager to be reported.
If you use a session manager such as CA TPX, CA Teleview, or CA SOLVE:Access, the terminals are logged on to the session manager, which establishes separate virtual sessions to various applications on behalf of the user. In this situation, a network monitor normally cannot determine which virtual sessions are associated with which physical terminal. If a terminal accesses an application through the session manager, most network monitors can tabulate the host and network response times only between the terminal and the session manager (provided the session manager uses definite response or you request dynamic definite response for the session manager). This means that no data is collected for the virtual session that the terminal has with the actual application through the session manager.
However, complete statistics are reported for all sessions established through the session manager. You can monitor your network performance while running the session manager and obtain all of the vital performance statistics for your network.
