概要

このチェックは、Hive の Hive Metastore と HiveServer2 の 2 つを監視します。

計画と使用

インフラストラクチャーリスト

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

ブラウザトラブルシューティング

Hive のセットアップ

Hive Metastore と HiveServer2 のメトリクスを有効化するには、以下のプロパティを追加して、HIVE_HOME/conf/hive-site.xml にある Hive コンフィギュレーションファイルを編集します。
```
<property>
  <name>hive.metastore.metrics.enabled</name>
  <value>true</value>
</property>
<property>
  <name>hive.server2.metrics.enabled</name>
  <value>true</value>
</property>
```
HiveServer2、Hive Metastore、またはその両方の JMX リモート接続を有効にします。たとえば、以下のように HADOOP_CLIENT_OPTS 環境変数を設定します。
```
export HADOOP_CLIENT_OPTS="$HADOOP_CLIENT_OPTS -Dcom.sun.management.jmxremote \
-Dcom.sun.management.jmxremote.authenticate=false -Dcom.sun.management.jmxremote.ssl=false \
-Dcom.sun.management.jmxremote.port=8808"
```
次に、HiveServer2 または Hive Metastore を再起動します。Hive Metastore と HiveServer2 で同じ JMX 接続を共有することはできません。

メトリクスベース SLO

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

ホストで実行中の Agent でこのチェックを構成する場合は、以下の手順に従ってください。コンテナ環境の場合は、コンテナ化セクションを参照してください。

メトリクスの収集

Hive のパフォーマンスデータを収集するには、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 hive.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 hive.d/conf.yaml を参照してください。
このチェックでは、インスタンスあたりのメトリクス数が 350 に制限されています。返されたメトリクスの数は、情報ページに表示されます。以下で説明するコンフィギュレーションを編集することで、関心があるメトリクスを指定できます。収集するメトリクスをカスタマイズする方法については、JMX チェックのドキュメントで詳細な手順を参照してください。制限数以上のメトリクスを監視する必要がある場合は、Datadog のサポートチームまでお問い合わせください。
Agent を再起動します。

収集データ

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。以下のように、datadog.yaml でこれを有効にする必要があります。
```
logs_enabled: true
```
Hive のログの収集を開始するには、次の構成ブロックを hive.d/conf.yaml ファイルに追加します。
```
  logs:
    - type: file
      path: /tmp/<USER>/hive.log
      source: hive
      service: '<SERVICE_NAME>'
      log_processing_rules:
        - type: multi_line
          name: new_log_start_with_date
          pattern: \d{4}\-\d{2}\-\d{2}
```
path パラメーターと service パラメーターの値を変更し、環境に合わせて構成してください。使用可能なすべての構成オプションの詳細については、サンプル hive.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

Datadog-Hive インテグレーションを使用してメトリクスを収集するには、JMX を使用したオートディスカバリーガイドを参照してください。

収集データ

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": "hive", "service": "<サービス名>", "log_processing_rules":{"type":"multi_line","name":"new_log_start_with_date", "pattern":"\d{4}\-\d{2}\-\d{2}"}}`

検証

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