Correct me if I am wrong but the load on a unix system is not quite 
nescessary related to the CPU usage.

You can get the load info for example with: uptime
  19:24:23 up 165 days,  1:09,  3 users,  load average: 0.02, 0.02, 0.00

And your CPU usage with: vmstat
procs -----------memory---------- ---swap-- -----io---- --system-- ----cpu----
  r  b   swpd   free   buff  cache   si   so    bi    bo   in    cs us sy id wa
  0  0   1072  67176 184720 792936    0    0     0    76 1138   110  0  0 100  0

While there usually is a relation between the two of them they are two 
different things.

The question is which of these two do you (raghavendra kristam) want?

There is a check_load plugin that does the load thing. For most alerting 
purposes that is quite enough. As th load tends to go up if you are low on 
memory.
