RE: What jobs were using high disk usage?

MPG Performance Navigator has a tool that will show this, Graphs, Current day, jobs, top job disk IO
Also, at V7R1, I was told that there are some additional perf tools that are now part of base i5OS.

Those messages would show me what started and stopped within that time period. Neither display any I/O counts. And if it was a job that never ends but just goes active I would get nothing. This is popular with a vast majority of the jobs in a Domino subsystem.

Rob, QHST messages - CPF1124 and CPF1164 - can be looked at - not with
DSPLOG, however, which doesn't show all the information you can get.

I think TAATOOLS has a tool for revealing all the goodness in QHST*. If
you don't have that, you can read the files directly - messages are on
multiple records. For CPF1164 there's a ton of stuff, including, IIRC
from 10 years ago, IO information.

More info in CL Programming and Work Management guides.

Sent performance data off for analysis. Got a message something like "
GDISYS has high disk arm utilization from 4:30am to 7:00am. Do you know
what type of jobs are normally running at that time?" How do I get a

of jobs that time by I/O? Keeping in mind that I/O could be DB2 or

stream

files.
