Notes supervision - plugin Nagios - centreon_plugins.pl

Voir :

Configure those extra SNMP options in the host/host template configuration in the SNMPEXTRAOPTIONS macro.

snmpwalk centreon-plugins
-a --authprotocol
-A --authpassphrase
-u --snmp-username
-x --privprotocol
-X --privpassphrase
-l not needed (automatic)
-e --securityengineid
-E --contextengineid

On lance une fois cpan pour le configurer 

cpan
 
# On ferme la session puis on la reouvre pour sourcer le .bashrc
exit
 
# Ou
source ~/.bashrc
cpan common/sense.pm
cpan Types/Serialiser.pm
cpan JSON
 
# Pour la commande net-snmp-config necessaire à cpan SNMP
#sudo apt-get install libsnmp-dev
#sudo yum install net-snmp
 
cpan SNMP

Wrapper en bash

Dans notre cas les plugins sont tous dans /usr/local/nagios/libexec/ mais si on fait un lien symbolique ln -s /usr/local/nagios/libexec/centreon-plugins-develop/src/centreon_plugins /usr/local/nagios/libexec/ ça ne fonctionne pas.

D'où ce petit wrapper.

centreon_plugins 

#! /bin/bash
set -euo pipefail
 
SCRIPT_DIR=$(readlink -m "$(dirname "$0")")
cd "${SCRIPT_DIR}/centreon-plugins-develop/src/" || exit 2

exec perl ./centreon_plugins.pl "$@"
