How often should I monitor the CPU and memory usage ?

Hi,
can you please post the output of lparstat -i ... this would be helpful to determine what kind of system you have and if it's capped or uncapped and how much resources are in the shared pool
We are monitoring our systems for peak performance - 100% cpu usage for more than 1 min (4 measure intervals every 20 seconds) on capped systems (these lpars that don't have a shared pool where they can get more cpu if required) and we have setup a custom alert that let us know once computational memory crosses 80% or pagingspace 5% - here we measure every 5 min.
Please ge aware the AVM value in the vmstat -I output is in 4k pages ... and computational memory usage is all that really counts in a box (that is sufficient tuned). If your box is or not is something we cannot tell you without any outputs
Kind regards
