Prérequis​
Afin de contrôler votre base de données Redis, le collecteur doit pouvoir exécuter la commande INFO (cf: https://redis.io/commands/INFO).
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
- CentOS 7
dnf install centreon-pack-applications-databases-redis
dnf install centreon-pack-applications-databases-redis
apt install centreon-pack-applications-databases-redis
yum install centreon-pack-applications-databases-redis
- Quel que soit le type de la licence (online ou offline), installez le connecteur Redis Database 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
- CentOS 7
dnf install centreon-plugin-Applications-Databases-Redis
dnf install centreon-plugin-Applications-Databases-Redis
apt install centreon-plugin-applications-databases-redis
yum install centreon-plugin-Applications-Databases-Redis

- 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_database_redis.pl \
--plugin=database::redis::plugin \
--custommode='perlmod' \
--server='10.0.0.1' \
--port='6379' \
--username='' \
--password='' \
--sentinel='' \
--sentinel-port='' \
--service='' \
--mode=cpu \
--warning-sys='' \
--critical-sys='' \
--warning-user='' \
--critical-user='' \
--warning-sys-children='' \
--critical-sys-children='' \
--warning-user-children='' \
--critical-user-children=''
La commande devrait retourner un message de sortie similaire à :
OK: system: 7 % user: 73 % system children: 93 % user children: 80 % | 'cpu.system.usage.percentage'=7%;;;0;100'cpu.user.usage.percentage'=73%;;;0;100'cpu.system.children.usage.percentage'=93%;;;0;100'cpu.user.children.usage.percentage'=80%;;;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 :
/usr/lib/centreon/plugins/centreon_database_redis.pl \
--plugin=database::redis::plugin \

--dyn-mode | Specify a mode with the module's path (advanced). |
--list-mode | List all available modes. |
--mode-version | Check minimal version of mode. If not, unknown error. |
--version | Return the version of the plugin. |
--custommode | When a plugin offers several ways (CLI, library, etc.) to get information the desired one must be defined with this option. |

--debug | Display debug messages. |
--filter-perfdata | Filter perfdata that match the regexp. Example: adding --filter-perfdata='avg' will remove all metrics that do not contain 'avg' from performance data. |
--filter-perfdata-adv | Filter perfdata based on a "if" condition using the following variables: label, value, unit, warning, critical, min, max. 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%;;;; |
--change-perfdata --extend-perfdata | Change or extend perfdata. Syntax: --extend-perfdata=searchlabel,newlabel,target[,[newuom],[min],[m ax]] Common examples: Convert storage free perfdata into used: --change-perfdata='free,used,invert()' Convert storage free perfdata into used: --change-perfdata='used,free,invert()' Scale traffic values automatically: --change-perfdata='traffic,,scale(auto)' Scale traffic values in Mbps: --change-perfdata='traffic_in,,scale(Mbps),mbps' Change traffic values in percent: --change-perfdata='traffic_in,,percent()' |
--extend-perfdata-group | Add new aggregated metrics (min, max, average or sum) for groups of metrics defined by a regex match on the metrics' names. Syntax: --extend-perfdata-group=regex,namesofnewmetrics,calculation[,[ne wuom],[min],[max]] regex: regular expression namesofnewmetrics: how the new metrics' names are composed (can use $1, $2... for groups defined by () in regex). calculation: how the values of the new metrics should be calculated newuom (optional): unit of measure for the new metrics min (optional): lowest value the metrics can reach max (optional): highest value the metrics can reach Common examples: Sum wrong packets from all interfaces (with interface need --units-errors=absolute): --extend-perfdata-group=',packets_wrong,sum(packets_(discard |error)_(in|out))' Sum traffic by interface: --extend-perfdata-group='traffic_in_(.*),traffic_$1,sum(traf fic_(in|out)_$1)' |
--change-short-output --change-long-output | Modify the short/long output that is returned by the plugin.

--opt-exit | Replace the exit code in case of an execution error (i.e. wrong option provided, SSH connection refused, timeout, etc). Default: unknown. |
--output-ignore-perfdata | Remove all the metrics from the service. The service will still have a status and an output. |
--output-ignore-label | Remove the status label ("OK:", "WARNING:", "UNKNOWN:", CRITICAL:") from the beginning of the output. Example: 'OK: Ram Total:...' will become 'Ram Total:...' |
--output-xml | Return the output in XML format (to send to an XML API). |
--output-json | Return the output in JSON format (to send to a JSON API). |
--output-openmetrics | Return the output in OpenMetrics format (to send to a tool expecting this format). |
--output-file | Write output in file (can be combined with json, xml and openmetrics options). E.g.: --output-file=/tmp/output.txt will write the output in /tmp/output.txt. |
--disco-format | Applies only to modes beginning with 'list-'. Returns the list of available macros to configure a service discovery rule (formatted in XML). |
