Prérequis​
Afin de superviser vos équipements Linux, le serveur SNMP doit être configuré sur ceux-ci. Les versions 2 et 3 sont recommandées.
Configuration du serveur SNMP​
Note : les commandes ci-après peuvent changer en fonction de la distribution. Des documentations sont disponibles sur les sites officiels des éditeurs.
Ci-dessous, un exemple de fichier snmpd.conf (remplacer my-snmp-community par la communauté que vous souhaitez utiliser).
com2sec notConfigUser default my-snmp-community
group notConfigGroup v1 notConfigUser
group notConfigGroup v2c notConfigUser
view centreon included .1.3.6.1
view systemview included .1.3.6.1.2.1.1
view systemview included .1.3.6.1.2.1.25.1.1
access notConfigGroup "" any noauth exact centreon none none
access notConfigGroup "" any noauth exact systemview none none
includeAllDisks 10%
Il est nécessaire de redémarrer le processus SNMP après avoir modifié le fichier de configuration.
Assurez-vous que le processus SNMP est configuré pour démarrer automatiquement lors du redémarrage du serveur.
Flux réseau​
La communication doit être possible sur le port UDP 161 depuis le collecteur Centreon vers le serveur Linux supervisé.
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-snmp
dnf install centreon-pack-operatingsystems-linux-snmp
apt install centreon-pack-operatingsystems-linux-snmp
yum install centreon-pack-operatingsystems-linux-snmp
- Quel que soit le type de la licence (online ou offline), installez le connecteur Linux SNMP 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-Operatingsystems-Linux-Snmp
dnf install centreon-plugin-Operatingsystems-Linux-Snmp
apt install centreon-plugin-operatingsystems-linux-snmp
yum install centreon-plugin-Operatingsystems-Linux-Snmp

- 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 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_linux_snmp.pl \
--plugin=os::linux::snmp::plugin \
--mode=interfaces \
--hostname=10.0.0.1 \
--snmp-version='2c' \
--snmp-community='my-snmp-community' \
--interface='.*' \
--name \
--add-status \
--add-traffic \
--critical-status='' \
--warning-in-traffic='80' \
--critical-in-traffic='90' \
--warning-out-traffic='80' \
--critical-out-traffic='90' \
--verbose
La commande devrait retourner un message de sortie similaire à :
OK: All interfaces are ok | *interface_name*#interface.traffic.in.bitspersecond'=20b/s;80;90;;' *interface_name*#interface.traffic.out.bitspersecond'=20b/s;80;90;;
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_linux_snmp.pl \
--plugin=os::linux::snmp::plugin \
--list-mode

--nagvis-perfdata | Display traffic perfdata to be compatible with NagVis widget. |
--interface | Check only the interfaces with the specified IDs (OID indexes, e.g.: 1,2,...). If empty, all interfaces will be monitored. To filter on interface names, see --name. |
--name | With this option, the interfaces will be filtered by name (givenin option --interface) instead of OID index. The name matching mode supports regular expressions. |
--regex-id | With this option, interface IDs will be filtered using the --interface parameter as a regular expression instead of a list of IDs. |
--speed | Set interface speed for incoming/outgoing traffic (in Mb). |
--speed-in | Set interface speed for incoming traffic (in Mb). |
--speed-out | Set interface speed for outgoing traffic (in Mb). |
--map-speed-dsl | Get interface speed configuration for interfaces of type 'ADSL' and 'VDSL2'. Syntax: --map-speed-dsl=interface-src-name,interface-dsl-name E.g: --map-speed-dsl=Et0.835,Et0-vdsl2 |
--force-counters64 | Force to use 64 bits counters only. Can be used to improve performance. |
--force-counters32 | Force to use 32-bit counters (even with SNMP versions 2c and 3). To use when 64-bit counters are buggy. |
--reload-cache-time | Time in minutes before reloading cache file (default: 180). |
--oid-filter | Define the OID to be used to filter interfaces (default: ifName) (values: ifDesc, ifAlias, ifName, IpAddr). |
--oid-display | Define the OID that will be used to name the interfaces (default: ifName) (values: ifDesc, ifAlias, ifName, IpAddr). |
--oid-extra-display | Add an OID to display. |
--display-transform-src --display-transform-dst | Modify the interface name displayed by using a regular expression. Example: adding --display-transform-src='eth' --display-transform-dst='ens' will replace all occurrences of 'eth' with 'ens' |
--show-cache | Display cache interface data. |
Option | Description |
---|---|
--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'). |
--warning-uptime | Warning threshold. |
--critical-uptime | Critical threshold. |
--add-sysdesc | Display system description. |
--force-oid | Can choose your OID (numeric format only). |
--check-overload | Uptime counter limit is 4294967296 and overflow. With that option, we manage the counter going back. But there is a few chance we can miss a reboot. |
--reboot-window | To be used with check-overload option. Time in milliseconds (default: 5000) You increase the chance of not missing a reboot if you decrease that value. |
--unit | Select the time unit for thresholds. May be 's' for seconds, 'm'for minutes, 'h' for hours, 'd' for days, 'w' for weeks. Default is seconds. |
