How to monitor thread/CPU/memory usage of a particular process

veryangryman

Can anyone help with this?

Im looking to take a simple snapshot of a particular process. I know of top, prstat, ps -ef ETC ETC but they all give long lists. Just want a simple script/command to look at one process

Also, i only know the process by name, not PID so will probably need some funky code to get the PID i guess...

Thanks for any help! :pac:

Something like ps -ef | grep [process name] will return just the line you are intersted in and you could then extract the PID from that (Please don't ask me how ).

you can use pgrep to get pid of a process by name. this can return more than 1 result by the way.

prstat can be used with -p option for listing of single process.

if you have a unique process, that is, only 1 instance of it executed on the system, then you could use:

prstat -p `pgrep xclock`

there backticks, not quotes (above the tab key)

Something like this should work, I haven't tried this out:
ps -ef | grep <process | grep -v grep | cut -f 3 -d ' '

Change the -f number until you get the right number

Thats cool but how would you specifically get the CPU for instance?

Those ps -ef command only gives the PID

I think this is what you are looking for:

ps -eo comm,uid,pid,%cpu,%mem | grep <name-of-process>

Have a look at the man page for ps, to see what other information you can print out.
