インテグレーションバージョン4.5.0

ZooKeeper ダッシュボード

概要

ZooKeeper チェックは、クライアント接続とレイテンシーの追跡、未処理リクエスト数の監視などを行います。

セットアップ

インストール

ZooKeeper チェックは Datadog Agent パッケージに含まれています。ZooKeeper サーバーに追加でインストールする必要はありません。

構成

包含リスト

バージョン 3.5 以降、ZooKeeper には 4lw.commands.whitelist パラメーターが追加されました。4 文字コマンドを許可する例については、ZooKeeper クラスターオプションを参照してください。デフォルトでは、srvr だけがホワイトリストに登録されています。インテグレーションはこれらのコマンドに基づいて行われるので、stat と mntr をホワイトリストに追加してください。

SSL の有効化

ZooKeeper 3.5 で SSL 認証を使用できるようになりました。ZooKeeper での SSL 設定については、ZooKeeper SSL ユーザーガイドを参照してください。

ZooKeeper で SSL の設定が完了すると、SSL を使用して Datadog Agent を構成し、ZooKeeper に接続できるようになります。JKS ファイルによってすでに認証設定が済んでいる場合は、次のステップに従って JKS ファイルを TLS/SSL コンフィギュレーション用の PEM ファイルに変換します。

次のコマンドの例は、JKS truststore ファイルと keystore ファイルが呼び出された場合を仮定しています。

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

また、両サイドの keystore ファイルと truststore ファイルが、互いの証明書およびエイリアスの server_cert と client_cert を持っているとします。つまり、Java ZooKeeper クライアントがすでに ZooKeeper サーバーに接続できる状態です。秘密キーにパスワードが設定されている場合は、コンフィグオプション tls_private_key_password の config.yaml ファイルにこのパスワードが含まれていることを確認してください。

JKS ファイルを PEM ファイルに変換するには

クライアントの truststore には信頼できるサーバーの証明書が含まれているため、ca_cert.pem ファイルを client_truststore.jks から取得します。
```
keytool -exportcert -file ca_cert.pem -keystore client_truststore.jks -alias server_cert -rfc
```
クライアントの keystore にはエイリアス client_cert のクライアントの証明書が含まれているため、cert.pem ファイルを client_keystore.jks から取得します。
```
keytool -importkeystore -srckeystore client_keystore.jks -destkeystore cert.p12 -srcstoretype jks -deststoretype pkcs12 -srcalias client_cert
```
openssl pkcs12 コマンドを実行します。これにより、クライアント証明書と証明書の秘密キーをエクスポートします。tls_cert コンフィグオプションにより、証明書と秘密キーを含む PEM ファイルを読み取って、パースできます。パスワード保護されていないファイルを取得するには、このコマンドに -nodes を追加します。
```
openssl pkcs12 -in cert.p12 -out cert.pem
```

ホスト

ホストで実行中の Agent に対してこのチェックを構成するには

ZooKeeper のメトリクスとログの収集を開始するには、Agent のコンフィギュレーションディレクトリのルートにある conf.d/ フォルダーの zk.d/conf.yaml ファイルを編集します。使用可能なすべてのコンフィギュレーションオプションについては、サンプル zk.d/conf.yaml を参照してください。
Agent を再起動します。

ログ収集

Agent バージョン 6.0 以降で利用可能

ZooKeeper はデフォルトで log4j ロガーを使用します。ファイルへのログ記録をアクティブにし、フォーマットをカスタマイズするには、log4j.properties ファイルを編集します。

  # 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

Datadog のインテグレーションパイプラインは、デフォルトで、次の変換パターンをサポートします。
```
  %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
```
別の形式に対応する場合は、インテグレーションパイプラインを複製して編集してください。
Datadog Agent で、ログの収集はデフォルトで無効になっています。以下のように、datadog.yaml ファイルでこれを有効にします。
```
logs_enabled: true
```

zk.d/conf.yaml の下部にある、コンフィギュレーションブロックのコメントを解除して編集します。

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])

path および service パラメーターの値を変更し、環境に合わせて構成します。使用可能なすべてのコンフィギュレーションオプションについては、サンプル zk.d/conf.yaml を参照してください。

Agent を再起動します。

コンテナ化

コンテナ環境の場合は、オートディスカバリーのインテグレーションテンプレートのガイドを参照して、次のパラメーターを適用してください。

メトリクスの収集

パラメーター	値
`<INTEGRATION_NAME>`	`zk`
`<INIT_CONFIG>`	空白または `{}`
`<INSTANCE_CONFIG>`	`{"host": "%%host%%", "port": "2181"}`

ログ収集

Agent バージョン 6.0 以降で利用可能

Datadog Agent で、ログの収集はデフォルトで無効になっています。有効にする方法については、Kubernetes ログ収集を参照してください。

パラメーター	値
`<LOG_CONFIG>`	`{"source": "zookeeper", "service": "<サービス名>"}`

検証

Agent の status サブコマンドを実行し、Checks セクションで zk を探します。

収集データ

メトリクス

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.avg_latency`	`zookeeper.latency.avg`
`zookeeper.max_latency`	`zookeeper.latency.max`
`zookeeper.min_latency`	`zookeeper.latency.min`
`zookeeper.packets_received`	`zookeeper.packets.received`
`zookeeper.packets_sent`	`zookeeper.packets.sent`
`zookeeper.num_alive_connections`	`zookeeper.connections`
`zookeeper.znode_count`	`zookeeper.nodes`
