I'm in the same spot and have a problem open with IBM. Normally it's
suppose to report the CPU by an interval, but there is a table that's
filling up when the MONITOR INTERVAL is set to or defaulted to 1 min.
They have advised me to use 2 min.
---- abbreviated problem conversations ----
The problem with PROCLOG only containing mean lines and not details was
recently uncovered internally. The problem appears to be that the
output has exceeded the REDISP value, which defaults to 120. The maximum
is 720 lines. To find the current value, issue the command
.
FC MONCOLL REDISP QUERY
.
to change the REDISP value, issue the command
.
FC MONCOLL REDISP 720
.
to set the maximum number of lines to be displayed.
.
Note: You may need to increase the size of the PERFSVM virtual storage
if you increase the REDISP to its maximum. This is because those lines
have to live in virtual storage along with everything else PERFKIT is
doing.
.
Still investigating your other concerns. Will let you know what we
find.

Sorry. There is an alternative to increasing the REDISP setting. You
can also increase the CP MONITOR interval, e.g. from 1 minute to 2
minutes. This seems to have the same result as changing the REDISP
value. We are working on a fix to this particular problem, though there
is no APAR open at this time.

The REDISP default/values are as Mike stated. Consider that value as to
the number of entries allowed in this 'table', which resides in the
vstore of the PERFSVM machine. So if you change the monitor interval
from 1 to 2 minutes, you will have 1/2 the amount of entries in the
table in the same amount of time. I think there is consideration of
a possible increase in this table size for future work.

Subject: PERFKIT: CPU usage by time intervals
Hi,
Is there any way in batch PERFKIT to get a report
that shows CPU usage broken down by periods?
I tried to do an INTERIM CPU and got:
FCXPRT374E INTERIM period not available for CPU
Thanks,
Shimon
