[Nagiosplug-help] load plugin

[Russell Scibetti]

Are you just calling the check_load plugin as it is to check the load on 
remote servers?  check_load must be run locally on the box you are 
checking.  If you aren't doing this, then you are actually just getting 
the load on your local monitoring machine for every check_load call 
(would explain them being identical!).

To use check_load for remote servers, you need to install the plugins 
physically on the remote machines and then either use:

check_by_ssh - to ssh to the remote box, execute the plugin and return 
the result

check_nrpe - Also install nrpe (nagios remote plugin executor) on the 
remote machines and configure it to run the load check.  You would then 
use the check_nrpe plugin from the monitoring server (read the docs for 
more on this)

nagios-statd - A daemon that runs on each remote machine that you query 
from the monitoring box to get the health of the remote machine (load, 
disk, etc).  I don't know much on this option

Hope this helps.
