Présentation

Ce check surveille Apache Flume.

Configuration

Le check Flume n’est pas inclus avec le package de l’Agent Datadog : vous devez donc l’installer.

Installation

Pour l’Agent v7.21+/6.21+, suivez les instructions ci-dessous afin d’installer le check Flume sur votre host. Consultez la section Utiliser les intégrations de la communauté pour effectuer une installation avec l’Agent Docker ou avec des versions antérieures de l’Agent.

  1. Exécutez la commande suivante pour installer l’intégration de l’Agent :

    datadog-agent integration install -t datadog-flume==<INTEGRATION_VERSION>
    
  2. Configurez votre intégration comme une intégration de base.

Configuration

  1. Configurez l’Agent Flume pour activer JMX en ajoutant les arguments JVM suivants à votre flume-env.sh :
export JAVA_OPTS="-Dcom.sun.management.jmxremote -Dcom.sun.management.jmxremote.port=5445 -Dcom.sun.management.jmxremote.authenticate=false -Dcom.sun.management.jmxremote.ssl=false"
  1. Modifiez le fichier flume.d/conf.yaml dans le dossier conf.d/ à la racine du répertoire de configuration de votre Agent pour commencer à recueillir vos données de performance Flume. Consultez le fichier d’exemple flume.d/conf.yaml pour découvrir toutes les options de configuration disponibles.

    Ce check prévoit une limite de 350 métriques par instance. Le nombre de métriques renvoyées est indiqué sur la page d’informations. Choisissez les métriques qui vous intéressent en modifiant la configuration ci-dessous. Pour découvrir comment modifier la liste des métriques à recueillir, consultez la documentation relative aux checks JMX afin d’obtenir des instructions détaillées. Si vous devez surveiller davantage de métriques, contactez l’assistance Datadog.

  2. Redémarrez l’Agent.

Validation

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