Google Cloud Load Balancing

概要

Google Cloud Load Balancing を使用すると、負荷分散されたコンピューティングリソースを単一または複数のリージョンに分配し、高可用性要件を満たすことができます。また、1 つのエニーキャスト IP の背後にリソースを置き、インテリジェントなオートスケーリング機能を使用してリソースをスケーリングできます。

Datadog Google Cloud Platform インテグレーションを使用して、Google Cloud Load Balancing からメトリクスを収集できます。

セットアップ

メトリクスの収集

インストール

Google Cloud Platform インテグレーションをまだセットアップしていない場合は、最初にセットアップします。それ以上のインストール手順はありません。

収集データ

Google Cloud HTTP Loadbalancer のログは Google Cloud Logging で収集され、Cloud Pub/Sub トピックを通じて Dataflow ジョブに送信されます。まだの場合は、Datadog Dataflow テンプレートでロギングをセットアップしてください

これが完了したら、Google Cloud HTTP Loadbalancer のログを Google Cloud Logging から Pub/Sub トピックへエクスポートします。

  1. Google Cloud Logging のページに移動し、Google Cloud HTTP Loadbalancer のログを絞り込みます。
  2. シンクを作成し、シンクに適宜名前を付けます。
  3. 宛先として “Cloud Pub/Sub” を選択し、その目的で作成された Pub/Sub トピックを選択します。: Pub/Sub トピックは別のプロジェクトに配置できます。
  4. 作成をクリックし、確認メッセージが表示されるまで待ちます。
