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-devel cpan SNMP
Le plugin a besoin de pouvoir écrire

Exemple avec Fortigate

Note : Pour certain plugin il est important d'écrire --hostname=localhost et non --hostname localhost, de même pour les autres arguments
Exemple conf Nagios
commands.cfg
define command{ command_name check_centreon_snmp_linux_disk_all command_line $USER1$/centreon_plugins --plugin=os::linux::snmp::plugin --mode=storage --hostname=$HOSTADDRESS$ --snmp-version=3 --snmp-username "$USER6$" --authprotocol MD5 --authpassphrase "$USER7$" --filter-storage-type=hrStorageFixedDisk --add-access --critical-access=readOnly --warning-usage $ARG1$ --critical-usage $ARG2$ --name --regexp --storage='^((?!cdrom).)*$' }
mode multi
./centreon_plugins.pl --plugin=os::linux::snmp::plugin --hostname=localhost --snmp-version=3 --snmp-username "nagios" --authprotocol MD5 --authpassphrase "P@ssw0rd" --mode multi --modes-exec 'uptime,memory,swap,cpu'
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

Le plugin Centreon pour Stormshield n'est compatible que en MD5|SHA
source : https://docs.centreon.com/pp/integrations/plugin-packs/procedures/network-stormshield-snmp/
SNMP v3 only: Authentication protocol: MD5|SHA. Since net-snmp 5.9.1: SHA224|SHA256|SHA384|SHA512.
Hors AlmaLinux release 8.10 (Cerulean Leopard) n'est pas compatible net-snmp 5.9.1. J'ai essayé de bidouiller et même de compiler net-snmp mais ça ne fonctionne pas. Il faut soit utiliser MD5/SHA1, soit passer à AlmaLinux 9, soit utiliser la commande snmpwalk/snmpget.
