Présentation

Le check lighttpd de l’Agent surveille la disponibilité, les octets traités, les requêtes par seconde, les codes de réponse et bien plus encore.

Configuration

Installation

Le check lighttpd est inclus avec le package de l’Agent Datadog : vous n’avez donc rien d’autre à installer sur vos serveurs lighttpd.

En outre, vous pouvez installer mod_status sur vos serveurs lighttpd.

Configuration

Host

Pour configurer ce check lorsque l’Agent est exécuté sur un host :

Modifiez le fichier lighttpd.d/conf.yaml dans le dossier conf.d/ à la racine du répertoire de configuration de votre Agent. Consultez le fichier d’exemple lighttpd.d/conf.yaml pour découvrir toutes les options de configuration disponibles.
```
init_config:

instances:
  ## @param lighttpd_status_url - string - required
  ## Status url of your Lighttpd server.
  #
  - lighttpd_status_url: http://localhost/server-status?auto
```
Redémarrez l’Agent.

Environnement conteneurisé

Consultez la documentation relative aux modèles d’intégration Autodiscovery pour découvrir comment appliquer les paramètres ci-dessous à un environnement conteneurisé.

Paramètre	Valeur
`<NOM_INTÉGRATION>`	`lighttpd`
`<CONFIG_INIT>`	vide ou `{}`
`<CONFIG_INSTANCE>`	`{"lighttpd_status_url": "http://%%host%%/server-status?auto"}`

Collecte de logs

La collecte de logs est désactivée par défaut dans l’Agent Datadog. Vous devez l’activer dans datadog.yaml :
```
logs_enabled: true
```
Ajoutez ce bloc de configuration à votre fichier lighttpd.d/conf.yaml pour commencer à recueillir vos logs lighttpd :
```
logs:
  - type: file
    path: /path/to/my/directory/file.log
    source: lighttpd
```
Modifiez la valeur du paramètre path et configurez-la pour votre environnement. Consultez le fichier d’exemple lighttpd.d/conf.yaml pour découvrir toutes les options de configuration disponibles.
Redémarrez l’Agent.

Validation

Lancez la sous-commande status de l’Agent et cherchez lighttpd dans la section Checks.
