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-protocol-http
dnf install centreon-pack-applications-protocol-http
apt install centreon-pack-applications-protocol-http
yum install centreon-pack-applications-protocol-http
- Quel que soit le type de la licence (online ou offline), installez le connecteur HTTP Server 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-Protocol-Http
dnf install centreon-plugin-Applications-Protocol-Http

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_protocol_http.pl \
--plugin=apps::protocols::http::plugin \
--mode=response \
--hostname=10.0.0.1 \
--proto='http' \
--port='80' \
--urlpath='/' \
--warning='' \
--critical=''
La commande devrait retourner un message de sortie similaire à :
OK: response time 0.078s | 'http.response.time.seconds'=0.078s;;;0; 'http.response.size.count'=49602B;;;0; 'http.response.resolve.time.milliseconds'=4.176ms;;;0; 'http.response.connect.time.milliseconds'=4.176ms;;;0; 'http.response.processing.time.milliseconds'=44.163ms;;;0; 'http.response.transfer.time.milliseconds'=4.176ms;;;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_protocol_http.pl \
--plugin=apps::protocols::http::plugin \
--list-mode
Le plugin apporte les modes suivants :
Mode | Modèle de service associé |
---|---|

expected-content [code] | App-Protocol-HTTP-Expected-Content-custom |
json-content [code] | App-Protocol-HTTP-Json-Content-custom |

Options disponibles​
Options génériques​
Les options génériques sont listées ci-dessous :

---|---|
--mode | Define the mode in which you want the plugin to be executed (see--list-mode). |
--dyn-mode | Specify a mode with the module's path (advanced). |
--list-mode | List all available modes. |

--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. Syntax: --change-short-output=pattern~replacement~modifier Most commonly used modifiers are i (case insensitive) and g (replace all occurrences). Example: adding --change-short-output='OK~Up~gi' will replace all occurrences of 'OK', 'ok', 'Ok' or 'oK' with 'Up' |
--change-exit | Replace an exit code with one of your choice. Example: adding --change-exit=unknown=critical will result in a CRITICAL state instead of an UNKNOWN state. |

--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). |
