Clarification on Check_Load Plugin

Hi Jatin,
The Nagios plugins doesn't calculate anything, it just read the load averages
produced by the Linux/*nix OS itself.
Have a look at this article: http://www.linuxjournal.com/article/9001?page=0,0

If you execute following commands on the command line of your linux box you'll
see the numbers originate from your os itself:

#top
#w
#cat /proc/loadavg
#uptime
... most likely a couple more

The only thing the load plugin does is evaluating the threshold you defined to
the value returned by your OS.

Hope it helps

Jelle
