Hi,

I'm trying to obtain number of runnable processes from linux kernel. sar -q gives this information readily. However I'm trying to get this value from /proc filesystem. There is no file in /proc that gives this value directly, then how is runq-sz computed.

Tools like top, vmstat, and sar, simply look at all the processes in /proc, and count the number that are in runnable (R) state. -- All rights reversed.
