Does anyone know the best way to get the most granular CPU % for a
given PID? I have been testing with ps on AIX and it seems to cache
the CPU information. No matter how much the CPU % changes (monitoring
with topas), the ps output always displays the same CPU % as I keep
rerunning the command. I am using something like "ps aeux PID".
I need a solution that returns exact CPU % for a given PID as this is
being used in a larger script.
Thanks for any suggestions.

not sure if this is what you're after
ps -e -o pid,ppid,pcpu,etime,time,vsz,user,rssize,comm
I have a process monitoring script I'm working on, but it may be
different from what you're looking for. My angle is a java (hoik,
spit) memory leak/usage issue.
May be you need to investigate tprof

Thanks Henry. I actually ended up using "ps -p $pid -o
"pcpu,time,cpu"" which gives me the percentage, total CPU time, and
current cpu usage.

How much Java have you written, moron?
ps -euwww | grep pid
