Shell script to monitor process which uses more CPU
Hi all,
I want to monitor the CPU percentage using the shell script which i am going to put it under cron tab to be scheduled for running every 10 mins once.
I need to monitor the top 5 process which uses more CPU percentage. I am looking for a command which does this one.
Note: I am on RHEL 5 Enterprise Server

What about using the top command? Note that a process that has multiple threads can exceed 100% CPU if you have more than one CPU or core. You can run it in batch mode if you want to output this data to a file.
Sometimes, real fast is almost as good as real time.

Rubberman thanks for your time. I tried your suggestion by invoking top like this
top -bn 5 > toplog
Where the process are sorted out by CPU percentage.But this output has more details as it capture all the process. Here what i need is, i want to list only the top 5 of them. Is there a way i can cut those extra details from the top command so that i can concentrate on top 5 process only.
