OOB Solution for looping batch jobs

    Is there an OOB solution for identifying looping batch jobs in version 14.2 or 15.0? Or do you have to put something together for it?   

    https://docops.ca.com/ca-sysview/15-0/en/using-ca-sysview/job-and-output-management/access-the-system-activity-display

    We are looking at identifying jobs that have no SIO, little to no EXCP-cnt movement yet CPU utilization continues to increase over a given duration. Are there better metrics that can be used to ID that condition? Anyone else doing something different and can share?

    David,
    Consider a threshold like this:
    DEFINE JOBCPUT% RSCE = RSCEATTR JOB LIMIT 100 DURATION 5

    This would trigger for any batch job (RSCEATTR JOB) that averages 100% usage of a single CPU over the prior 5 minutes.  You could vary the LIMIT value based on the number of engines available on the LPAR, e.g. 200 would equate to monopolizing two CPUs.

    At present there is no built-in way to threshold on CPU usage in relation to I/O.  To do something like that would involve having SYSVIEW threshold on say cpu-usage, which could get picked up by automation like OPS/MVS, which could then interrogate the I/O usage aspect.
