Prérequis
Configuration SNMP de l'équipement
La configuration de SNMP sur un serveur Linux est expliquée dans la page de documentation du connecteur de supervision Linux SNMP.
Configuration de la connexion SSH sans mot de passe
NB : Il est très fortement recommandé de superviser le cluster à partir d'un collecteur plutôt qu'à partir du cluster.
Ouvrez une session en ligne de commande sur :
- le collecteur qui sera chargé de superviser le cluster
- chaque nœud de ce cluster
Une fois ces sessions ouvertes, lancez cette commande :
su - centreon-engine
À présent nous sommes dans l'environnement bash
de centreon-engine
. Lancez ensuite cette commande :
ssh-keygen -t ed25519 -a 100
Nous avons généré une paire de clés sur chaque serveur, ainsi que le répertoire ~/.ssh
.
Sur le collecteur, lancez cette commande pour afficher la clé publique créée :
cat ~/.ssh/id_ed25519.pub
Après avoir lancé cette commande, copiez le contenu du fichier qui s'est affiché sous la commande cat
et collez-le à la fin du fichier (probablement à créer) ~/.ssh/authorized_keys
des nœuds centraux, puis appliquez les bons droits sur le fichier (toujours en tant que centreon-engine
) :
chmod 600 ~/.ssh/authorized_keys
Une fois cette étape effectuée sur chaque nœud central, il ne reste plus qu'à initialiser une première connexion depuis le collecteur vers chacun des nœuds :
ssh <cluster-node-ip-address>
L'utilisateur centreon-engine
du collecteur est alors capable d'ouvrir une session SSH sur les deux nœuds centraux.
Il ne reste plus qu'à l'intégrer au groupe haclient
pour lui permettre d'exécuter les commandes nécessaires à la supervision du cluster :
usermod -a -G haclient centreon-engine
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 > Connecteurs > 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-ha centreon-pack-applications-pacemaker-ssh centreon-pack-operatingsystems-linux-snmp
dnf install centreon-pack-applications-monitoring-centreon-ha centreon-pack-applications-pacemaker-ssh centreon-pack-operatingsystems-linux-snmp
apt install centreon-pack-applications-monitoring-centreon-ha centreon-pack-applications-pacemaker-ssh centreon-pack-operatingsystems-linux-snmp
yum install centreon-pack-applications-monitoring-centreon-ha centreon-pack-applications-pacemaker-ssh centreon-pack-operatingsystems-linux-snmp
- Quel que soit le type de la licence (online ou offline), installez le connecteur Centreon-HA depuis l'interface web et le menu Configuration > Connecteurs > 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-pack-applications-pacemaker-ssh centreon-pack-operatingsystems-linux-snmp
dnf install centreon-pack-applications-pacemaker-ssh centreon-pack-operatingsystems-linux-snmp

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) :

Diagnostic des erreurs communes
Rendez-vous sur la documentation dédiée pour le diagnostic des erreurs communes des plugins Centreon.
The authenticity of host 'x.x.x.x (x.x.x.x)' can't be established
Attention, la tentative d'exécution du plugin et de connexion via SSH doivent impérativement se faire depuis le compte
centreon-engine
.
Le message complet ressemble à ce qui suit :
The authenticity of host 'x.x.x.x (x.x.x.x)' can't be established.
ECDSA key fingerprint is SHA256:xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx.
ECDSA key fingerprint is MD5:xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx.
Are you sure you want to continue connecting (yes/no)? UNKNOWN: Command too long to execute (timeout)...
Si vous obtenez ce message, cela signifie que vous n'avez pas accepté l'empreinte du serveur.
Pour y remédier il faut initier une première connexion :
ssh x.x.x.x
Puis taper 'yes' à l'invite suivante :
The authenticity of host 'x.x.x.x (x.x.x.x)' can't be established.
ECDSA key fingerprint is SHA256:xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx.
ECDSA key fingerprint is MD5:xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx.
Are you sure you want to continue connecting (yes/no)?
UNKNOWN: Command error: Permission denied, please try again
Le message complet ressemble à ce qui suit :
UNKNOWN: Command error: Permission denied, please try again. - Permission denied, please try again. - Permission denied (publickey,gssapi-keyex,gssapi-with-mic,password).
Si l'exécution de la sonde renvoie ce message, c'est que la clé publique du compte centreon-engine
du poller n'est pas correctement déposée sur le nœud que l'on cherche à superviser.
Il faut tout d'abord s'assurer que celle-ci (contenue dans /var/lib/centreon-engine/.ssh/id_ed25519.pub
) est bien présente dans le fichier /var/lib/centreon-engine/.ssh/authorized_keys
.
Si le point précédent est bien validé, alors s'assurer que les permissions du fichier authorized_keys
et du répertoire .ssh
qui le contient sont conformes à ce qui s'affiche suite à la commande :
ls -al /var/lib/centreon-engine/.ssh
Le résultat doit être conforme à ce qui suit :
total 20
drwx------ 2 centreon-engine centreon-engine 4096 Sep 4 14:44 .
drwxr-xr-x. 5 centreon-engine centreon-engine 4096 Sep 4 14:44 ..
-rw------- 1 centreon-engine centreon-engine 0 Sep 4 14:44 authorized_keys
Dans le cas contraire, lancer ces commandes :
chmod 700 /var/lib/centreon-engine/.ssh
chmod 600 /var/lib/centreon-engine/.ssh/authorized_keys
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_pacemaker_ssh.pl \
--plugin=apps::pacemaker::local::plugin \
--list-mode

--privprotocol | SNMP v3 only: Privacy protocol (privProtocol) used to encrypt messages. Supported protocols are: DES|AES and since net-snmp 5.9.1: AES192|AES192C|AES256|AES256C. |
--contextname | SNMP v3 only: Context name (contextName), if relevant for the monitored host. |
--contextengineid | SNMP v3 only: Context engine ID (contextEngineID), if relevant for the monitored host, given as a hexadecimal string. |
--securityengineid | SNMP v3 only: Security engine ID, given as a hexadecimal string. |
--snmp-errors-exit | Expected status in case of SNMP error or timeout. Possible values are warning, critical and unknown (default). |
--snmp-tls-transport | Transport protocol for TLS communication (can be: 'dtlsudp', 'tlstcp'). |
--snmp-tls-our-identity | X.509 certificate to identify ourselves. Can be the path to the certificate file or its contents. |
--snmp-tls-their-identity | X.509 certificate to identify the remote host. Can be the path to the certificate file or its contents. This option is unnecessary if the certificate is already trusted by your system. |
--snmp-tls-their-hostname | Common Name (CN) expected in the certificate sent by the host if it differs from the value of the --hostname parameter. |
--snmp-tls-trust-cert | A trusted CA certificate used to verify a remote host's certificate. If you use this option, you must also define --snmp-tls-their-hostname. |
--memcached | Memcached server to use (only one server). |
--redis-server | Redis server to use (only one server). Syntax: address[:port] |
--redis-attribute | Set Redis Options (--redis-attribute="cnx_timeout=5"). |
--redis-db | Set Redis database index. |
--failback-file | Failback on a local file if Redis connection fails. |
--memexpiration | Time to keep data in seconds (default: 86400). |
--statefile-dir | Define the cache directory (default: '/var/lib/centreon/centplugins'). |
--statefile-suffix | Define a suffix to customize the statefile name (default: ''). |
--statefile-concat-cwd | If used with the '--statefile-dir' option, the latter's value will be used as a sub-directory of the current working directory. Useful on Windows when the plugin is compiled, as the file system and permissions are different from Linux. |
--statefile-format | Define the format used to store the cache. Available formats: 'dumper', 'storable', 'json' (default). |
--statefile-key | Define the key to encrypt/decrypt the cache. |
--statefile-cipher | Define the cipher algorithm to encrypt the cache (default: 'AES'). |
--process-status | Filter process status. Can be a regexp. (default: 'running|runnable'). |
--process-name | Filter process name. |
--regexp-name | Allows to use regexp to filter process name (with option --process-name). |
--process-path | Filter process path. |
--regexp-path | Allows to use regexp to filter process path (with option --process-path). |
--process-args | Filter process arguments. |
--regexp-args | Allows to use regexp to filter process arguments (with option --process-args). |
--warning | Warning threshold of matching processes count. |
--critical | Critical threshold of matching processes count. |
--memory | Check memory usage. |
--warning-mem-each | Warning threshold of memory used by each matching processes (in Bytes). |
--critical-mem-each | Critical threshold of memory used by each matching processes (in Bytes). |
--warning-mem-total | Warning threshold of total memory used by matching processes (in Bytes). |
--critical-mem-total | Critical threshold of total memory used by matching processes (in Bytes). |
--warning-mem-avg | Warning threshold of average memory used by matching processes (in Bytes). |
--critical-mem-avg | Critical threshold of average memory used by matching processes (in Bytes). |
--cpu | Check CPU usage. Should be used with fix processes. If processespid changes too much, the plugin can't compute values. |
--warning-cpu-total | Warning threshold of CPU usage for all processes (in percent). CPU usage is in % of one CPU, so maximum can be 100% * number of CPU and a process can have a value greater than 100%. |
--critical-cpu-total | Critical threshold of CPU usage for all processes (in percent). CPU usage is in % of one CPU, so maximum can be 100% * number of CPU and a process can have a value greater than 100%. |
--top | Enable top memory usage display. |
--top-num | Number of processes in top memory display (default: 5). |
--top-size | Minimum memory usage to be in top memory display (default: 52428800 -> 50 MB). |
