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

[Vaibhav Jain <vjoss197@xxxxxxxxx>]

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 ?

 

Thanks
