Hello Roger, Thank you for all the great information! I changed the monitor sample configuration size to 600 as you suggested and the problem was corrected. Will this change stay in affect after an IPL or do I have to re-issue the command?

We ship with an ample size that is good for 'most' shops. However, if you monitor a lot of users or devices, this size may need to be increased): 1-MONITOR STOP 2-MONITOR SAMPLE CONFIG SIZE 600 3-RESTART THE PERFKIT If this increase does not correct the problem, restart with step 1, and increase the config size by another 300 (aka: 900 the 2nd time). If this corrects and no more error messages then you are good to go. Be aware: -Increasing the SAMPLE CONFIG SIZE could cause a need to increase the MONDCSS size as well (becuase the Sample Config size comes out of the MONDCSS SAMPLE area). But not to worry, the Perfkit will tell you via messages if this is needed. If you do need to increase the MONDCSS size, you will need to: A-MONITOR STOP B-Ensure there is NO OVERLAP with other DCSS/NSS in address range of MONDCSS (EX: Q NSS ALL MAP to find where all NSS are located) C-CP DEFSEG MONDCSS 9000-9AFF SC RSTD (example locations) D-CP SAVESEG MONDCSS E-RESTART the PERFKIT watching for any Error message at startup. You can also trim down the amount of users/devices being monitored via the MONITOR SAMPLE ENABLE/DISABLE USER userid or MONITOR SAMPLE ENABLE/DISABLE I/O CLASS/DEV xxxx (ref CP MONTOR SAMPLE command). I hope this helps. Roger Lunsford IBM z/VM CP/Perfkit/Monitor Level2/Level3
