How to know which are the server processes taking lot of CPU usage?

[Deepu Chakravarty]

I am running rp7420 with HPUX 11.11.
I want to know which are the processes taking lot of CPU usage. Through 'top' command I can know this fact. But I want to know only CPU% for all top 10 processes which are taking lot of CPU usage. How 'ps' command can be constructed so that I can know this fact?

Thanks in advance.

This memory leak detector uses some ps commands you can use. This and the man page can help you identify what you seem to seek.

Hi:

Define "...a lot of CPU usage". Does this mean as a cumulative amount since the process instantiation? Does this mean over n-interval?

How about this:

# UNIX95= ps -e -o pid= -o time= -o pcpu= -o comm=|sort -rk2,2|head -10

Note the whitespace after the equal sign in 'UNIX95'. This keeps this option set only for the duration of the command line.

The headings are suppressed for the output and only the top ten largest CPU processes are listed.

See the 'ps' manpages for more information.

Regards!

I need the CPU% of the following like the process which is taking 99.98% of the CPU usage. The process name is f60webmx

For your reference: I am attaching following some top processes list.

Why not use top(1) to get this info?
top -f top.out -n 10
sed -n -e '/^CPU TTY/,$ p' top.out
