Oracle Cloud ロードバランサ監視
概要
Oracleロードバランサは、バックエンドサーバー間でトラフィックを分散し、最適なパフォーマンスと信頼性を実現するフルマネージドのクラウドサービスです。
サーバーの過負荷を防ぎ、パブリックおよびプライベートのデプロイメントをサポートし、SSLターミネーション、正常性監視、接続の永続性といった機能を提供します。
Applications ManagerのOracleロードバランサ監視ツールは、すぐに使用できるパフォーマンスメトリックを提供し、ロードバランサ・インフラストラクチャの正常性と可用性を視覚化するのに役立ちます。管理者はWebクライアントにログインして、リアルタイムのトラフィック分散、バックエンドサーバーの正常性、ロードバランシングの効率性を監視し、シームレスなアプリケーションの可用性とパフォーマンスを確保できます。
監視対象パラメータ
監視タブをクリックして、監視カテゴリ ビューに移動します。クラウド アプリセクションのOracle Cloudで利用可能なロードバランサインスタンスをクリックします。3つのタブに分かれたOracleロードバランサの一括設定ビューが表示されます。
- 可用性タブでは、過去24時間か30日の可用性履歴がわかります。
- パフォーマンス タブでは、過去24時間か30日のステータスとイベントがわかります。
- リスト ビューでは、一括管理設定が可能です。
リストから監視をクリックすると、次の4つのタブで構成されるOracleロードバランサダッシュボードが表示されます。
