From: ElvisRS on 17 May 2010 13:55 Hi, I wanted to ask you if you know any way to measure cpu load caused by interrupts from network interface? I can get the number of interrupts from /proc/interrupts file but I can't get the information what is the percent of occupancy of the cpu by those. Someone has any idea? Greg

Presumably CPU profile such as oprofile, Caliper, etc, coupled with a bit of knowledge of what you want to consider "interrupt" code. rick jones -- No need to believe in either side, or any side. There is no cause. There's only yourself. The belief is in your own precision. - Joubert these opinions are mine, all mine; HP might not want them anyway... :) feel free to post, OR email to rick.jones2 in hp.com but NOT BOTH... |
