High CPU utilization detection from a kernel module

["Bizhan Gholikhamseh (bgholikh)" <bgholikh@xxxxxxxxx>]

HI

Is there any mechanism by which a kernel module can detect high CPU utilization? I can use sar and vmstat in the userland to monitor CPU utilization, but I need a way to detect it at kernel level for example 100% CPU utilization for over 10 msec or evern 1 sec.

 

Thanks,

Bizhan
