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-operatingsystems-linux-centreon-monitoring-agent
dnf install centreon-pack-operatingsystems-linux-centreon-monitoring-agent
apt-get install centreon-pack-operatingsystems-linux-centreon-monitoring-agent
Aucune version de Centreon supportée sur CentOS 7 n'est compatible avec Centreon Monitoring Agent.
-
Quel que soit le type de la licence (online ou offline), installez le connecteur Linux Centreon Monitoring Agent depuis l'interface web et le menu Configuration > Gestionnaire de connecteurs de supervision.
-
Créez le nouveau connecteur.
Dans le menu Configuration > Commandes > Connecteurs, cliquez sur Ajouter puis saisissez les champs suivants :
Paramètre | Valeur |
---|---|
Nom du connecteur | Centreon Monitoring Agent |
Description du connecteur | Centreon Monitoring Agent |
Ligne de commande | opentelemetry --processor=centreon_agent --extractor=attributes --host_path=resource_metrics.resource.attributes.host.name --service_path=resource_metrics.resource.attributes.service.name |
Utilisé par la commande | Selectionner toutes les commandes dont le nom correspond à OS-Linux-Centreon-Monitoring-Agent-* |
Statut du connecteur | Activé |
Plugin
Ce connecteur de supervision s'appuie sur une intégration prise en charge par Centreon Engine et ne requiert pas de plugin particulier sur les collecteurs.
Utiliser le connecteur de supervision
Utiliser un modèle d'hôte issu du connecteur
- Ajoutez un hôte à Centreon depuis la page Configuration > Hôtes.
- Complétez les champs Nom, Alias & IP Address/DNS correspondant à votre ressource.
- Appliquez le modèle d'hôte OS-Linux-Centreon-Monitoring-Agent-custom. Une liste de macros apparaît. Les macros vous permettent de définir comment le connecteur se connectera à la ressource, ainsi que de personnaliser le comportement du connecteur.
- Renseignez les macros désirées. Attention, certaines macros sont obligatoires.
Macro | Description | Valeur par défaut | Obligatoire |
---|---|---|---|
CENTREONAGENTPLUGINS | Path where the Centreon Plugins can be found. | /usr/lib/centreon/plugins | X |
CENTREONAGENTSTATEFILEDIR | Define the cache directory. | /dev/shm/ | X |
CENTREONAGENTEXTRAOPTIONS | Any extra option you may want to add to every command (a --verbose flag for example). Toutes les options sont listées ici. |
- Déployez la configuration. L'hôte apparaît dans la liste des hôtes supervisés, et dans la page Statut des ressources. La commande envoyée par le connecteur est indiquée dans le panneau de détails de l'hôte : celle-ci montre les valeurs des macros.
Utiliser un modèle de service issu du connecteur
- Si vous avez utilisé un modèle d'hôte et coché la case Créer aussi les services liés aux modèles, les services associés au modèle ont été créés automatiquement, avec les modèles de services correspondants. Sinon, créez les services désirés manuellement et appliquez-leur un modèle de service.
- Renseignez les macros désirées (par exemple, ajustez les seuils d'alerte). Les macros indiquées ci-dessous comme requises (Obligatoire) doivent être renseignées.

- Déployez la configuration. Le service apparaît dans la liste des services supervisés, et dans la page Statut des ressources. La commande envoyée par le connecteur est indiquée dans le panneau de détails du service : celle-ci montre les valeurs des macros.
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 hôte Linux en vous connectant avec l'utilisateur root. 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) :
sudo -u centreon-monitoring-agent /usr/lib/centreon/plugins/centreon_linux_local.pl \
--plugin='os::linux::local::plugin' \
--mode='cpu' \
--warning-core='99' \
--critical-core='' \
--warning-average='40' \
--critical-average='' \
--statefile-dir='/dev/shm/'
La commande devrait retourner un message de sortie similaire à :
OK: CPU(s) average usage is 2.95 % | 'cpu.utilization.percentage'=2.95%;0:40;;0;100 '0#core.cpu.utilization.percentage'=3.07%;0:99;;0;100 '1#core.cpu.utilization.percentage'=2.83%;0:99;;0;100
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 :
sudo -u centreon-monitoring-agent /usr/lib/centreon/plugins/centreon_linux_local.pl \
--plugin='os::linux::local::plugin' \

Variables must be written either %{variable} or %(variable). Example: adding --filter-perfdata-adv='not (%(value) == 0 and %(max) eq "")' will remove all metrics whose value equals 0 and that don't have a maximum value. |
--explode-perfdata-max | Create a new metric for each metric that comes with a maximum limit. The new metric will be named identically with a '_max' suffix). Example: it will split 'used_prct'=26.93%;0:80;0:90;0;100 into 'used_prct'=26.93%;0:80;0:90;0;100 'used_prct_max'=100%;;;; |
