Check load plugin configuration on a local machine.

I've got a 24 core box over here, obviously I need to tweak the
configuration of the check_load plugin as it seems designed for a single
core machine by default.

define service{
use                             generic-service
host_name                       localhost
service_description             Current Load
check_command                   check_load!20!18!16!22!19!18
}



My understanding is that this breaks down as follows

1, 5, 15 minute load average. 

I've set it to the following.

Warning thresholds. (17 is 70% of 24)
20!18!16

So warn if it is currently 20, or averaging 17.

Critical thresholds. 
22!19!18

Only one core, not maxed out, bad. Average above 22, bad.

Anyhow, my question is. Is this a sane configuration. It's pretty
generous with load. My usual load average is actually:

1.88 2.08 2.16

Any advice appreciated,

Bryan Hunt
