System monitors (e.g. Omegamon) can detect when a job is above or below a
specified threshhold.
Use your automation product to detect this situation and take the dump /
provide notification. If you don't have a monitor, then output from the MVS D
A, command and calculate the difference
Jon,
Are you working for a ISV ? I am curious

If you use ADRDSSU to backup OMVS files, the files are quiesced during
the backup.

Thank you, we know this and we have some alerts during this
quiesce period, but this slow down is not during backup.

How in the first place do you see the slow down? Perhaps your reply could
yield a good answer to you question.

The CPU usage for the process , address space , drops from about
70% to 0%, the process writes to some log files ,
100-300 message pro minute, in this period no message in this logs.

Can the PFA help here , or any other idea how we can detect this ?
Try RMF Monitor III. It maintains history so that you can look at the system
and the work that was running (or stalling) in the past. Just allocate large
collection datasets so that the data is still there in the morning.

Others have offered diagnostic suggestions, but to respond to your
original query: PFA monitors a number of things, but time used CPU per
address space is not among them. For a list of PFA's checks, see
Chapter 9 in z/OS Problem Management (the 2.1 version is here:
Have you got multiple periods in the associated WLM Service Class?

O.k. so no PFA for this.
It is a test machine, so during the complete stress test, this was the
only active process, so no WLM or something like this.
Monitored with RMF and the system CPU also dropped to a few percent.
Seems to me , the process is in wait , I would like to get DUMP's and
13 matches
