[users@httpd] Apache Server Status CPU usage information

[Supratik Goswami <su...@gmail.com>]

Hi All !

I have Apache/2.2.6 running in my Fedora 8 system. I have enabled the
server-status directive in the httpd.conf file and I am able to view the
current state of the Apache server status. My question is 1) what is meant
by (u s cu cs) in the CPU usage and how those values are calculated, can
anyone please explain me in details. I found through google this link [
http://corelib.rubyonrails.org/classes/Benchmark/Tms.html] where the
information is not in detail.I am confused, if child processes are mostly
using the CPU then in which circumstance the parent uses the CPU. 2) What is
meant by CPU load, is it for that point of time or average from uptime. 3)
Is the CPU load calculated from the CPU usage. My Apache server status is
given as below... can anyone please help me to resolve these queries.
