Présentation

Ce check permet de surveiller Spark avec l’Agent Datadog. Recueillez des métriques de Spark concernant :

  • Les pilotes et exécuteurs : blocs RDD, mémoire utilisée, espace disque utilisé, durée, etc.
  • Les RDD : nombre de partitions, mémoire utilisée, espace disque utilisé.
  • Les tâches : nombre de tâches actives, ignorées, ayant échoué, totales.
  • Les statuts des jobs : nombre de jobs actifs, terminés, ignorés, ayant échoué.

Remarque : Les métriques Spark Structured Streaming ne sont pas prises en charge.

Configuration

Installation

Le check Spark est inclus avec le package de l’Agent Datadog. Vous n’avez donc rien d’autre à installer sur votre master Mesos (pour Spark sur Mesos), ResourceManager YARN (pour Spark sur YARN) ou master Spark (pour Spark en mode standalone).

Configuration

Host

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

  1. Modifiez le fichier spark.d/conf.yaml dans le dossier conf.d/ à la racine du répertoire de configuration de votre Agent. Les paramètres suivants peuvent nécessiter une mise à jour. Consultez le fichier d’exemple spark.d/conf.yaml pour découvrir toutes les options de configuration disponibles.

    init_config:
    
    instances:
      - spark_url: http://localhost:8080 # Spark master web UI
        #   spark_url: http://<Mesos_master>:5050 # Mesos master web UI
        #   spark_url: http://<YARN_ResourceManager_address>:8088 # YARN ResourceManager address
    
        spark_cluster_mode: spark_yarn_mode # default
        #   spark_cluster_mode: spark_mesos_mode
        #   spark_cluster_mode: spark_yarn_mode
        #   spark_cluster_mode: spark_driver_mode
    
        # required; adds a tag 'cluster_name:<CLUSTER_NAME>' to all metrics
        cluster_name: "<CLUSTER_NAME>"
        # spark_pre_20_mode: true   # if you use Standalone Spark < v2.0
        # spark_proxy_enabled: true # if you have enabled the spark UI proxy
    
  2. 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.

ParamètreValeur
<NOM_INTÉGRATION>spark
<CONFIG_INIT>vide ou {}
<CONFIG_INSTANCE>{"spark_url": "%%host%%:8080", "cluster_name":"<NOM_CLUSTER>"}

Collecte de logs

  1. La collecte de logs est désactivée par défaut dans l’Agent Datadog. Vous devez l’activer dans datadog.yaml :

     logs_enabled: true
    
  2. Supprimez la mise en commentaire du bloc de configuration des logs du fichier spark.d/conf.yaml et modifiez les paramètres. Modifiez les valeurs des paramètres type, path et service en fonction de votre environnement. Consultez le fichier d’exemple spark.d/conf.yaml pour découvrir toutes les options de configuration disponibles.

     logs:
       - type: file
         path: <LOG_FILE_PATH>
         source: spark
         service: <SERVICE_NAME>
         # To handle multi line that starts with yyyy-mm-dd use the following pattern
         # log_processing_rules:
         #   - type: multi_line
         #     pattern: \d{4}\-(0?[1-9]|1[012])\-(0?[1-9]|[12][0-9]|3[01])
         #     name: new_log_start_with_date
    
  3. Redémarrez l’Agent.

Consultez la [documentation de Datadog][6] pour découvrir comment configurer l’Agent afin de recueillir les logs dans un environnement Docker.

Renvoie CRITICAL si l’Agent ne parvient pas à se connecter au master standalone de l’instance Spark. Si ce n’est pas le cas, renvoie OK.

spark.mesos_master.can_connect
Renvoie CRITICAL si l’Agent ne parvient pas à se connecter au master Mesos de l’instance Spark. Si ce n’est pas le cas, renvoie OK.

spark.application_master.can_connect
Renvoie CRITICAL si l’Agent ne parvient pas à se connecter à l’ApplicationMaster de l’instance Spark. Si ce n’est pas le cas, renvoie OK.

spark.resource_manager.can_connect
Renvoie CRITICAL si l’Agent ne parvient pas à se connecter au ResourceManager de l’instance Spark. Si ce n’est pas le cas, renvoie OK.

spark.driver.can_connect
Renvoie CRITICAL si l’Agent ne parvient pas à se connecter au ResourceManager de l’instance Spark. Si ce n’est pas le cas, renvoie OK.

Dépannage

Spark sur AWS EMR

Pour recueillir des métriques Spark lorsque Spark est configuré sur AWS EMR, [utilisez les actions Bootstrap][8] pour installer l’[Agent Datadog][10] :

Pour l’Agent v5, créez le fichier de configuration /etc/dd-agent/conf.d/spark.yaml avec les [valeurs appropriées pour chaque nœud EMR][9].

Pour l’Agent v6 ou v7, créez le fichier de configuration /etc/datadog-agent/conf.d/spark.d/conf.yaml avec les [valeurs appropriées pour chaque nœud EMR][11].
