Prérequis
SNMP
SNMP doit être configuré sur chaque collecteur supervisé. Vous pouvez vous aider de cette documentation pour mettre en place rapidement une configuration SNMP simple.
Échange de clef SSH
Un des services accompagnant le pack dispose d'une vérification réalisée à l'aide de SSH. Le serveur central doit pouvoir se connecter à tous les collecteurs supervisés.
Le serveur central réalise ses vérifications en tant qu'utilisateur système centreon-engine, et se connectera en SSH au collecteur avec l'utilisateur centreon.
Les étapes ci-dessous décrivent l'échange de clef SSH entre le central et le collecteur :
- Depuis le collecteur supervisé par le central, paramétrer un mot de passe pour l'utilisateur centreon :
passwd centreon
- Depuis le central, créer et copier la nouvelle clef SSH de l'utilisateur centreon-engine vers le collecteur :
su - centreon-engine
ssh-keygen -t ed25519 -a 100
ssh-copy-id -i ~/.ssh/id_ed25519.pub centreon@<IP_POLLER>
Installer le connecteur de supervision
Pack
- Si la plateforme est configurée avec une licence online, l'installation d'un paquet n'est pas requise pour voir apparaître le connecteur dans le menu Configuration > Gestionnaire de connecteurs de supervision. Au contraire, si la plateforme utilise une licence offline, installez le paquet sur le serveur central via la commande correspondant au gestionnaire de paquets associé à sa distribution :
- Alma / RHEL / Oracle Linux 8
- Alma / RHEL / Oracle Linux 9
- Debian 11 & 12
- CentOS 7
dnf install centreon-pack-applications-monitoring-centreon-poller
dnf install centreon-pack-applications-monitoring-centreon-poller
apt install centreon-pack-applications-monitoring-centreon-poller
yum install centreon-pack-applications-monitoring-centreon-poller
- Quel que soit le type de la licence (online ou offline), installez le connecteur Centreon Poller depuis l'interface web et le menu Configuration > Gestionnaire de connecteurs de supervision.
Plugin
À partir de Centreon 22.04, il est possible de demander le déploiement automatique du plugin lors de l'utilisation d'un connecteur. Si cette fonctionnalité est activée, et que vous ne souhaitez pas découvrir des éléments pour la première fois, alors cette étape n'est pas requise.
Plus d'informations dans la section Installer le plugin.
Utilisez les commandes ci-dessous en fonction du gestionnaire de paquets de votre système d'exploitation :
- Alma / RHEL / Oracle Linux 8
- Alma / RHEL / Oracle Linux 9
- Debian 11 & 12
- CentOS 7
dnf install centreon-plugin-Applications-Monitoring-Centreon-Poller
dnf install centreon-plugin-Applications-Monitoring-Centreon-Poller

Comment puis-je tester le plugin et que signifient les options des commandes ?
Une fois le plugin installé, vous pouvez tester celui-ci directement en ligne
de commande depuis votre collecteur Centreon en vous connectant avec
l'utilisateur centreon-engine (su - centreon-engine
). Vous pouvez tester
que le connecteur arrive bien à superviser une ressource en utilisant une commande
telle que celle-ci (remplacez les valeurs d'exemple par les vôtres) :
/usr/lib/centreon/plugins/centreon_centreon_poller.pl \
--plugin=apps::centreon::local::plugin \
--hostname=10.0.0.1 \
--mode=broker-stats \
--broker-stats-file='/var/lib/centreon-engine/*-module-stats.json' \
--filter-name='' \
--warning-speed-events='' \
--critical-speed-events='' \
--warning-queued-events='' \
--critical-queued-events='' \
--warning-unacknowledged-events='' \
--critical-unacknowledged-events='' \
--warning-status='' \
--critical-status='%\{type\} eq "output" and %\{queue_file_enabled\} =~ /true|yes/i' \
--verbose \
--ssh-username='centreon'
La commande devrait retourner un message de sortie similaire à :
OK: Broker statistics are ok | '*endpoint*#speed-events'=events/s;;;0;'*endpoint*#queued-events'=events;;;0;'*endpoint*#unacknowledged-events'=events;;;0;
Diagnostic des erreurs communes
Rendez-vous sur la documentation dédiée pour le diagnostic des erreurs communes des plugins Centreon.
Modes disponibles
Dans la plupart des cas, un mode correspond à un modèle de service. Le mode est renseigné dans la commande d'exécution du connecteur. Dans l'interface de Centreon, il n'est pas nécessaire de les spécifier explicitement, leur utilisation est implicite dès lors que vous utilisez un modèle de service. En revanche, vous devrez spécifier le mode correspondant à ce modèle si vous voulez tester la commande d'exécution du connecteur dans votre terminal.
Tous les modes disponibles peuvent être affichés en ajoutant le paramètre
--list-mode
à la commande :
/usr/lib/centreon/plugins/centreon_centreon_poller.pl \
--plugin=apps::centreon::local::plugin \
--list-mode
