Percent cpu utilization per process

[kaushikbramesh]

Hello all,

I'm porting a ksh script written to monitor the percent cpu utilization and percent memory utilization for certain process in the process table on Tru64 Unix. This script uses ps auxw command to get the %cpu and %memory utilization for all the processe in the ps table. Is there a equivalent command I can use on HP-UX to get the %CPU utilization and %memory utilization. HP-UX version HP-UX B 11.23.

You can use,

a) top
b) UNIX95= ps -ef -o cpu,pcpu,pid,comm (cpu %)

I believe that what you are looking for is "ps" command.

"man ps" - for more options.

You can get %CPU, but I don't think you can get %mem.

I hope you can get memory size utilization with top or UNIX95 + ps command.

# UNIX95= ps -ef -o cpu,pcpu,pid,sz,vsz,comm gives that.

# glance may give (Don't know)
# openview + extract may give that too.

# UNIX95= ps -e -o pid,comm,pcpu|sort -krn3 and # top will be helpful to % utilization.

Hi,

Using export UNIX95=true
ps ps -ef -o uid,pid,pcpu,vsz,sz,state,stime,time,comm

gives me the %CPU. I dont see any arguments to find the %MEM.

yes,

You can only get %CPU statistics. You can memory size utilization but not the %MEM statistics.

It's sz and vsz fields:

sz - The size in physical pages of the core image of the process, including text, data, and stack space. Physical page size is defined by _SC_PAGE_SIZE in the header file.

vsz - The size in kilobytes (1024 byte units) of the core image of the process.

(from man)

Hello all,

Thanks for all your quick replies.
Heres a sample of what I get from ps auxw on Tru64

USER PID %CPU %MEM VSZ RSS TTY S STARTED TIME COMMAND
root 274249 20.5 1.6 73.2M 66M ?? S Mar 02 2-00:28:26 /usr/sbin/cron
kaushik 230295 0.3 0.0 11.2M 1.6M ?? S 09:41:37 0:03.35 /usr/dt/bin/dtterm -ls
root 292798 0.1 0.0 2.61M 328K pts/5 S 11:19:59 0:00.02 ksh

I extract column 3 and column 4 as a routine monitoring. If either the CPU util or the MEM util exceeds a certain limit I need to raise a trap.

The ps command indeed solves the problem of %CPU. I have not found anything in the ps man pages to give me the %MEM per process.

Thanks and regards
Kaushik

Hi, You may need to look at this page for more information,

Tru64 is support %MEM with pmem field.

Well, if you want % value, you can alsways calculate it.

(proc mem / total mem) * 100
