I'm an admin on a v5r4 system. We have a report utility that eats up storage for no apparent reason. Yesterday I checked the wrksyssts and we were at 34% which is normal for us. At about 12pm I got a critical storage alert message that we were at 90% then mins later 95%. I found the job and forced it to end and we went back to about 40%. Here's the thing. This job does not produce data or write to a splf. It didn't have a big joblog. I can find no reason that it would chew up the system like that. I would like to monitor jobs for the space/storage/system resources (?) they take so I can catch run away jobs before we reach a critical point on our system. I've already changed our lower limit alert to 75% to warn us sooner but I'd like to monitor at the job level instead. Any ideas? User limits maybe?
