This topic provides some recommendations that will help you plan how to make the best use of CICSPlex® SM’s monitoring functions in your enterprise.
You are recommended not to make the interval too short, not only because CICSPlex SM’s overheads grow as the monitor interval reduces, but also because too short an interval is unlikely to provide you with useful statistics.
You can set the retention period to any value between 1 and 1440 minutes (24 hours). You can specify a retention period on the monitor specification, in which case that period applies to every CICS system associated with the monitor specification. Alternatively, you can specify a retention period in the CICSPlex SM CICS system definition.
