RE: Urgent: How to monitor jobs for .....

["Alistair Rooney" <alistairr@xxxxxxxxxx>]

Bill,

Agreed! There is also the school of thought that says if your machine is
consistently running below 100% then it is under-utilised. A perfectly
balanced machine should run at 90% + for most of the day. You are correct
when you say if this is the only job running why shouldn't it have 70%? (or
99% for that matter).

Unfortunately, some people seem to think that when the system hits 100%
CPU (or whatever number) that they should start killing things off.
Doesn't matter if that one job is really the only thing running, it's
taking too much resources.  Doesn't matter that it's a batch job that
gives up the resources to the interactive jobs as they need it, it's
taking too much resources.

Oops, there I went again.

This is one of those things that I keep trying to get people to
understand, but they just don't really want to.

Rajeev, please understand that this is not at you specifically, but at
this question/problem/issue in general.

Just because the process is taking up 70% of the CPU, you really need to
ask other questions:  What else is running.  Is this s batch or
interactive job.  If interactive, should it be a batch job.  Is it just
poorly written, and if re-written, will it become more normal...

Why is this urgent?  If a job uses more than 70 percent CPU on your
system,
why should they be killed?

Hello All,

Is there any way I can monitor jobs in the system for their possible CPU
usage
times exceeding some limit, say, 70% and kill them if they exceed.
Moreover, the other job attributes such as elapsed time etc. also have
to be
momitored.

Please send me the solutions at your earliest.

Thanks in advance.

Rajeev.
