Have a look at the man page of "ps", especially the "-o" option and its various arguments. For instance, the following will show the CPU%, the PID and the CMD columns of each process, sorted by CPU consumption:
You might probably want to modify the command according to your needs and what you find in the man page.
Using HP-UX v11
Need to monitor cpu and memory usage, total for system and separately for each user in command-line mode.
Found out next ways to monitor total cpu usage under hp-ux:
1) vmstat, also shows free memory
2) sar -M
ps -eo user,pcpu - does not work, means 'user-defined format'... (4 Replies)
Hi All,
Can anyone help me..
I want to know the command to check the overall CPU usage of the server.

Hi all
Can anyone advise/confirm whether total CPU usage when running sar is %user+%system+%iowait or is it %user+%system only?
I want to confirm whether I am having a CPU-bound problem or not.
This is a single-CPU VMware machine.

dappprof
dappprof(1m) USER COMMANDS dappprof(1m)NAME
dappprof - profile user and lib function usage. Uses DTrace.
SYNOPSIS
dappprof [-acehoTU] [-u lib] { -p PID | command }
DESCRIPTION
dappprof prints details on user and library call times for processes as a summary style aggragation. By default the user fuctions are
traced, options can be used to trace library activity. Output can include function counts, elapsed times and on cpu times.
The elapsed times are interesting, to help identify functions that take some time to complete (during which the process may have slept).
CPU time helps us identify syscalls that are consuming CPU cycles to run.
Since this uses DTrace, only users with root privileges can run this command.
OPTIONS -a print all data
-c print function counts
-e print elapsed times, ns
-o print CPU times, ns
-T print totals
-p PID examine this PID
-u lib trace this library instead
-U trace all library and user functions
EXAMPLES
run and examine the "df -h" command,
# dappprof df -h
print elapsed times, on-cpu times and counts for "df -h",
# dappprof -ceo df -h
print elapsed times for PID 1871,
# dappprof -p 1871
print all data for PID 1871,
# dappprof -ap 1871
FIELDS
CALL Function call name
ELAPSED
Total elapsed time, nanoseconds
CPU Total on-cpu time, nanoseconds
COUNT Number of occurrences
DOCUMENTATION
See the DTraceToolkit for further documentation under the Docs directory. The DTraceToolkit docs may include full worked examples with ver-
bose descriptions explaining the output.
EXIT
dappprof will sample until Ctrl-C is hit.
