Re: How to get cpu utilization through code with least overhead?

July 30, 2011


      Thanks !!
I looked at the code for top command again and I could see /proc/stat being
used. So I guess
that should be the best way to do it.

Hi,
Is there any other way to do this? If I need to write a kernel module
that
needs to get cpu utilization
should I still use proc/stat ? Is there a kernel function that can be
used
in a module ?
To get the information that's shown in /proc/stat, I'd suggest having a
look at fs/proc/stat.c in the kernel tree.
