Monitor SNA sessions and maintain history only for key applications, subsystems, and resources, such as CICS and IMS, to reduce the amount of management information being collected.
Business Value:
Maintaining session information for critical SNA-based applications assists network problem diagnosis. A quicker mean time to repair ensures that impact to critical business services is minimized. Conversely, collecting information that is insignificant in a business context places unnecessary overhead on the system.
Additional Considerations:
The Network Tracking System (NTS) component of CA NetMaster NM for SNA collects information about SNA sessions on your system. In a busy network, large amounts of management information can be collected. Therefore, collect only information of significance to your network management needs. For less important applications and resources, you can decide not to monitor the sessions or not to keep the history.
Even for critical applications and resources, it may not be desirable to monitor session activity continually. It may be more appropriate to activate monitoring only when problems occur.
