概要

Neo4j は、ネイティブのグラフストレージ、高度なセキュリティ、スケーラブルな速度最適化アーキテクチャ、ACID コンプライアンスをインテグレーションし、関係ベースのクエリの予測可能性と整合性を確保するエンタープライズ強度の高いグラフデータベースです。Neo4j は、より自然でつながった状態でデータを保存・管理し、データ関係を維持することで、高速なクエリ、分析のためのより深いコンテキスト、そして苦痛のない変更可能なデータモデルを提供します。

Neo4j メトリクスは、データベース管理者が Neo4j のデプロイをモニターできるようにします。DBA は、メモリ使用量 (ヒープとページキャッシュ)、トランザクション数、クラスターのステータス、データベースサイズ (ノード数、関係、プロパティを含む)、クエリパフォーマンスを把握したいと考えます。

このインテグレーションにより、すぐに使えるダッシュボードで Neo4j の重要なメトリクスを視覚化し、DBA が Neo4j データベースのトラブルシューティングと健全性のモニタリングを行えるようになります。

ホスト上で動作する Agent の場合。コンテナ環境では、これらの指示を適用するためのガイダンスとして、オートディスカバリーインテグレーションテンプレートを参照してください。

インストール

neo4j チェックをホストにインストールするには

1. Datadog Agent をダウンロードしてインストールします。

2. neo4j チェックをホストにインストールするには

   datadog-agent integration install -t datadog-neo4j==<INTEGRATION_VERSION>
   

コンフィギュレーション

1. neo4j のパフォーマンスデータ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 neo4j.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の詳細については、neo4j.d/conf.yaml のサンプルを参照してください。

2. Datadog は、dogstatsd_stats_port と expvar_port をポート 5000 でリッスンしています。neo4j.conf ファイルで、server.discovery.listen_address と server.discovery.advertised_address を 5000 以外のポートを使用するように変更する必要があります。

3. Agent を再起動します。

検証

Agent の status サブコマンドを実行し、Checks セクションで neo4j を探します。

収集データ
