vmstat returns good val for cpuIdle put ps shows no active process
hi
i'm running a shell script that checks the amount of cpu idle either using /usr/bin/vmstat 1 2 or sar 1 2 (on unixware) before i run some tests(if cpu idle greater than 89 I run them).
These tests are run on many platforms, linux(suse, redhat) hp-ux, unixware, aix, solaris, tru64.
When the test for cpu idle fails I do a
to try to find out what process is hogging the cpu, at best the output does not clearly show which process is affecting it or at worst does not return anything other than 0.0 values for %CPU for all processes.
I know that ps -e -o pcpu returns a percentage value - the CPU time divided by the time the process has been running and it will never add up to 100% but I would expect something useful.
When I run the top command, it shows 1 process as being Stopped. This is not a zombie, but simply a stopped process. Unfortunately, I can't figure out how to tell which process this is, nor why it is in a stopped state? Any way of finding this out? (7 Replies)

Any help will be greatly appreciated.
