If you're looking for CPU usage examine the output of:
ps -p 22657 --no-headers -o "%C"
If that is what you're looking for then stick it in a bash script loop
that repeats the command at your required frequency (hint: use "sleep"
to pause a few seconds and check the ps manual page for other output
(e.g. memory usage) that you might also want.
