capturing weighted cpu

Clarence Rebolledo — Mon, 03 Sep 2007 23:00:04 GMT

I run scripts using "top -d1" and piped to a file. Then I string the file and grep for my process and check the wcpu because of the programs memory leak and it run up to 100%. Is there another command to use to capture the weighted cpu or when the process gets to 100%. When it reaches 100% it locks up where nobody can not do any work on the system.

You can do as follows.

UNIX95= ps -ef =o pid,ppid,ruser,cpu,pcpu,args|grep "your_processes"

Then whatever you want to do...

Shalom,

Try this:

Consider it beta code, but its coming along nicely.

Thanks for your answer. One of the reasons for writing was to check if any utility or command was put out by HP that I may of missed. Both answers use the ps command and it shows time used by the process not weighted cpu. This process runs 24x7 and it's the weighted cpu that concerns me because when the process reaches 100% wcpu nothing else gets done on the server.

You do know about the "top -f file" option to give text output? I don't know if top allows you to use "-" as the file so you can send it to your pipe?

You mentioned CPU and memory leak. Why do you think there is a connection?

If you are worried about a memory leak, you can download wdb and use it's leak detection commands:
set heap-check on
info leaks

We are running a Vendors application and it is known to go high with it's Weighted CPU usage. About once a month I have to kill the process because it goes high on it's wcpu and you can see it using top. I do know about the -f command with top, thanks. It's the vendor's application that's bad and because we're using it, I have to watch this problem. Thanks for your help and informaion.
