Reply Link shapirus January 30, 2009, 10:53 pmCan someone please explain me how can it be when /proc/stats shows 414% total CPU usage (including the idle time) on a quad-core single The load average is a number corresponding to the average number of runnable processes on the system. For example in unix systems at /proc/uptime gives information of uptime of the system and the value is dynamic since it would be different every time you poll. Try following examples, iostat -d -x
iostat -d -m -x
iostat -x -d 2All you have to do is pass -x option. http://qaisoftware.com/cpu-usage/check-cpu-usage-on-linux.html
