Are you asking for a report of each USER's cpu utilization per time period (which would be INTERIM USER) or of the entire VM LPAR (which would be INTERIM LPAR)? The process is pretty much the same.
1) Gather monitor data. See the LINMON package as an example. Hint: Use some form of automation to shutdown and restart LINMON after the 23:59 monitor data is written. "MONWRITE CLOSE" is subject to time drift. You do not want your monitor data crossing midnight because PERFKIT does not like that. 2) Reduce the monitor data using PERFKIT BATCH. Contents of file LPARDATA MASTER A: SETTINGS LPARDATA SETTINGS A REPORTS LPARDATA REPORTS A LISTING LPARDATA LISTING X comment: X is a r/w workdisk/workspace Contents of the file LPARDATA SETTINGS A: FC SETTINGS REPFILID LPARDATA LISTING X FC SETTINGS INTERIM 1 MIN FC MONCOLL RESET CLEAR Contents of file LPARDATA REPORTS: INTERIM LPAR Command to create report PERFKIT BATCH LPARDATA MASTER A DISK monitordatafn monitordataft monitordatafm This generates the report LPARDATA LISTING which is minute by minute reports. You can then use PIPES to extract the data you are interested in. For example, I pipe the LISTING file, do a "joincont not leading /1/ keep" to get every page into one record, do a "strfind /1FCX126/" to keep only the report pages, and then use specs to pull the fields I want. -----Original Message----- From: The IBM z/VM Operating System [mailto:ib...@listserv.uark.edu] On Behalf Of Frank M.

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. Frank M. Ramaekers Jr. Systems Programmer MCP, MCP+I, MCSE & RHCE American Income Life Insurance Co.
