Présentation

Le check ZooKeeper vérifie les connexions client et les latences, surveille le nombre de requêtes non traitées et bien plus encore.

Configuration

Installation

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

Configuration

Liste d’inclusion

Depuis la version 3.5, ZooKeeper comprend le paramètre 4lw.commands.whitelist. Consultez la section sur les options de cluster ZooKeeper) pour découvrir un exemple permettant d’ajouter des commandes à 4 lettres. Par défaut, seule la commande srvr est ajoutée à la liste blanche. Ajoutez stat et mntr à la liste blanche, car le processus d’intégration repose sur ces commandes.

Activation de l’authentification SSL

La version 3.5 de ZooKeeper prend en charge l’authentification SSL. Pour découvrir comment configurer l’authentification SSL avec ZooKeeper, consultez le guide ZooKeeper à ce sujet (en anglais).

Après avoir configuré l’authentification SSL pour ZooKeeper, vous pouvez égalemet configuré l’Agent Datadog afin de le connecter à ZooKeeper via SSL. Si vous avez déjà configuré l’authentification à l’aide de fichiers JKS, suivez les étapes ci-dessous pour les convertir en fichiers PEM afin de procéder à la configuration TLS/SSL.

Les exemples de commandes suivants supposent que vos fichiers truststore et keystore JKS portent les noms suivants :

server_truststore.jks
server_keystore.jks
client_truststore.jks
client_keystore.jks

Nous partons également du principe que les fichiers keystore et truststore côté client et serveur disposent chacun des certificats réciproques, avec les alias server_cert et client_cert. Ainsi, le client ZooKeeper Java peut d’ores et déjà se connecter à un serveur ZooKeeper. Si votre clé privée est protégée par un mot de passe, assurez-vous d’indiquer le mot de passe pour l’option de configuration tls_private_key_password du fichier config.yaml.

Pour convertir des fichiers JKS en fichiers PEM :

Récupérez le fichier ca_cert.pem à partir du fichier client_truststore.jks, puisque le truststore du client contient le certificat du serveur fiable :
```
keytool -exportcert -file ca_cert.pem -keystore client_truststore.jks -alias server_cert -rfc
```
Récupérez le fichier cert.pem à partir du fichier client_keystore.jks, puisque le keystore du client contient le certificat du client pour l’alias client_cert :
```
keytool -importkeystore -srckeystore client_keystore.jks -destkeystore cert.p12 -srcstoretype jks -deststoretype pkcs12 -srcalias client_cert
```
Exécutez la commande openssl pkcs12, afin d’exporter le certificat client et la clé privée du certificat. L’option tls_cert peut lire et parser le fichier PEM, qui contient à la fois le certificat et la clé privée. Si vous souhaitez obtenir un fichier qui n’est pas protégé par un mot de passe, ajoutez -nodes à la commande :
```
openssl pkcs12 -in cert.p12 -out cert.pem
```

Host

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

Modifiez le fichier zk.d/conf.yaml dans le dossier conf.d/ à la racine du répertoire de configuration de votre Agent pour commencer à recueillir vos métriques et logs ZooKeeper. Consultez le fichier d’exemple zk.d/conf.yaml pour découvrir toutes les options de configuration disponibles.
Redémarrez l’Agent.

Collecte de logs

Disponible à partir des versions > 6.0 de l’Agent

ZooKeeper utilise le logger log4j par défaut. Pour activer la journalisation dans un fichier et personnaliser le format, modifiez le fichier log4j.properties :

  # Set root logger level to INFO and its only appender to R
  log4j.rootLogger=INFO, R
  log4j.appender.R.File=/var/log/zookeeper.log
  log4j.appender.R.layout=org.apache.log4j.PatternLayout
  log4j.appender.R.layout.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss} %-5p [%t] %c{1}:%L - %m%n

Par défaut, le pipeline d’intégration de Datadog prend en charge les expressions de conversion suivantes :
```
  %d{yyyy-MM-dd HH:mm:ss} %-5p %c{1}:%L - %m%n
  %d [%t] %-5p %c - %m%n
  %r [%t] %p %c %x - %m%n
```
Vérifiez d’avoir bien dupliqué et modifié le pipeline d’intégration si vous utilisez un autre format.
La collecte de logs est désactivée par défaut dans l’Agent Datadog. Vous devez l’activer dans datadog.yaml :
```
logs_enabled: true
```

Supprimez la mise en commentaire du bloc de configuration suivant en bas de votre fichier zk.d/conf.yaml, puis modifiez-le :

logs:
  - type: file
    path: /var/log/zookeeper.log
    source: zookeeper
    service: myapp
    #To handle multi line that starts with yyyy-mm-dd use the following pattern
    #log_processing_rules:
    #  - type: multi_line
    #    name: log_start_with_date
    #    pattern: \d{4}\-(0?[1-9]|1[012])\-(0?[1-9]|[12][0-9]|3[01])

Modifiez les valeurs des paramètres path et service et configurez-les pour votre environnement. Consultez le fichier d’exemple zk.d/conf.yaml pour découvrir toutes les options de configuration disponibles.

Redémarrez l’Agent.

Données collectées

Métriques

As of zookeeper 3.4.0, the mntr admin command is provided for easy parsing of zookeeper stats. This check first parses the stat admin command for a version number. If the zookeeper version supports mntr, it is also parsed.

Duplicate information is being reported by both mntr and stat: the duplicated stat metrics are only kept for backward compatibility.

Important: if available, make use of the data reported by mntr, not stat.

Metric reported by `mntr`	Duplicate reported by `stat`

`zookeeper.max_latency`	`zookeeper.latency.max`
