Implementing MAS resource monitoring (MRM)
You should start by implementing MRM on a system-by-system basis. Select a single resource type, such as connections or files, in a single CICS® system, and create these CICSPlex® SM objects:
- An evaluation definition, to identify the instances of the resource you are interested in, the frequency with which CICSPlex SM is to evaluate the resource status, how CICSPlex SM is to interpret its findings, and the severity to be assigned to a true condition
- An analysis definition, to identify the frequency with which CICSPlex SM is to analyze the results and the point at which an external notification should be issued
- An action definition, to identify the type of external notification to be issued
The interval between resource evaluations (as specified in the evaluation definition) and the intervals at which data is to be analyzed (as specified in the analysis definition) should be intelligently matched (and ideally the same). In particular, do not analyze the data more frequently than it is evaluated. Also, resource evaluations should be performed as infrequently as possible while still providing useful data: the more frequently data is collected, the greater the cost of its collection.
Begin by installing the analysis definition manually in the active CICS system. When you are satisfied that MAS resource monitoring is working as you expected, consider whether automatic installation of the analysis definition would be useful. If it would, add the analysis definition to an analysis group, and associate the analysis group with an analysis specification. At this point, decide whether to monitor additional resources in the same CICS system. To extend MAS resource monitoring to other resources, an additional evaluation definition would be required, an additional analysis definition might be required, but the original action definition could probably be reused.
