HAProxy Web API
Dépendances du connecteur de supervision
Les connecteurs de supervision suivants sont automatiquement installés lors de l'installation du connecteur HAProxy Web depuis la page Configuration > Gestionnaire de connecteurs de supervision :
Contenu du pack
Ce connecteur permet de superviser HAProxy (y compris les versions OSS/libres) en utilisant la page « stats » de HAProxy. Il ne supporte que le format json, le format csv n'est pas compatible.
Modèles
Le connecteur de supervision HAProxy Web apporte un modèle d'hôte :
- App-Haproxy-Web-custom
Le connecteur apporte les modèles de service suivants (classés selon le modèle d'hôte auquel ils sont rattachés) :
- App-Haproxy-Web-custom
- Non rattachés à un modèle d'hôte
Ce modèle d'hôte n'a pas de service associé par défaut. Utilisez les règles de découverte de services pour déployer vos services.
Alias | Modèle de service | Description | Découverte |
---|---|---|---|
Backend-Usage | App-Haproxy-Web-Backend-Usage-custom | Contrôle l'utilisation des 'backends' avec les "servers" associés | X |
Frontend-Usage | App-Haproxy-Web-Frontend-Usage-custom | Contrôle l'utilisation des 'frontends' avec les "listeners" associés | X |
Les services listés ci-dessus ne sont pas créés automatiquement lorsqu'un modèle d'hôte est appliqué. Pour les utiliser, créez un service manuellement et appliquez le modèle de service souhaité.
Si la case Découverte est cochée, cela signifie qu'une règle de découverte de service existe pour ce service.

Prérequis
Pour superviser les statistiques HAProxy via API vous devez activer l’interface des statistiques dans HAProxy.
Dans votre fichier de configuration haproxy.cfg
, ajoutez ou modifiez cette section :
listen stats
bind *:8404
stats enable
stats uri /haproxy?stats
stats auth username:password
stats refresh 10s
bind *:8404
: Expose la page des statistiques sur le port 8404.stats uri /haproxy?stats
: Définit l’URL d’accès aux statistiques.stats auth username:password
: Définit l’authentification (choisissez le couple username/password)stats refresh 10s
: Rafraîchit les statistiques toutes les 10 secondes (vous pouvez ajuster cette valeur à votre cas).
Vous pouvez vérifier l'accès à la page API (depuis un navigateur ou avec curl) :
curl -u username:password http://IP_HAPROXY:8404/haproxy?stats
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-haproxy-web
dnf install centreon-pack-applications-haproxy-web
apt install centreon-pack-applications-haproxy-web
yum install centreon-pack-applications-haproxy-web
- Quel que soit le type de la licence (online ou offline), installez le connecteur HAProxy Web 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-Haproxy-Web
dnf install centreon-plugin-Applications-Haproxy-Web
apt install centreon-plugin-applications-haproxy-web
yum install centreon-plugin-Applications-Haproxy-Web
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 App-Haproxy-Web-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 |
---|---|---|---|
HAPROXYUSERNAME | Specify the username for authentication (mandatory if --credentials is specified). | login | |
HAPROXYPASSWORD | Specify the password for authentication (mandatory if --credentials is specified). | password | |
HAPROXYPROTOCOL | Specify https if needed | http | |
HAPROXYPORT | Port used by the web server | 8404 |
- 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.

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_haproxy_web.pl \
--plugin=apps::haproxy::web::plugin \
--list-mode
Le plugin apporte les modes suivants :
Mode | Modèle de service associé |
---|---|
backend-usage [code] | App-Haproxy-Web-Backend-Usage-custom |
frontend-usage [code] | App-Haproxy-Web-Frontend-Usage-custom |
list-objects [code] | Used for service discovery |
