I want to monitor the power supplies from an HP DL380G8, but only have access to the ILO4.

So i look for the snmp adress for the powersupply via ILO4 and HP DL380. (and a “little try and error”).

I wrote a little plugin:  check_my_ps

(copy it to:  /usr/lib64/nagios/plugins/)


# check_my_ps
# check powersupply with snmp through ILO4
# v 1.0 21.06.2013 J.H.
# $1 = HostIP

PSUHealth=`snmpget -v 2c -c public $1 . | grep “INTEGER: 2″`

if [[ $? -ne 0 ]] ; then
echo “ERROR:Power Supply Problem – visit https://$1 for more information.”
exit 2
echo “OK: Powersupplies ok”
exit 0
in /etc/nagios/objects add entry to commands.cfg:

define command{
command_name         check_my_ps
command_line            $USER1$/check_my_ps $HOSTADDRESS$


in /etc/nagios/objects add entry to <servername.cfg>

define service{
use                                   generic-service
host_name                    myServer.sample.org
service_description    Power Supply
check_command         check_my_ps


It works in my enviroment, maybe it doesn’t work in yours. Take it as a sample for own plugins.
