Ajout des perfdata au plugin check_procs de Nagios

Le plugin original check_proc de de Nagios ne fournit pas de données de performances utilisables par pnp pour générer des graphs, il existe un patch à appliquer au sources, mais il faut du coup recompiler le plugin.

Pour éviter cela, voici un petit script intermédiaire qu’il suffit d’appeler à la place de check_procs :

 

#!/bin/bash

proc_status=`/usr/lib/nagios/plugins/check_procs -w $2 -c $4`
code=$?

perfdata="processus="`echo $proc_status |cut -f 3 -d " "`";"

echo $proc_status"|"$perfdata
exit $code

 

 

Script Nagios de monitoring SNMP de cartes MegaRaid

Pour continuer dans le monitoring du raid des cartes LSI MegaRaid, voici un autre script plus ancien qui permet de vérifier l’état du raid par requête SNMP et renvoi un code et un message utilisable par Nagios.
