Ambassador API Gateway

Supported OS: Linux Mac OS Windows

概要

Ambassador からリアルタイムにメトリクスを取得すると、以下のことができます。

  • マイクロサービスのパフォーマンスを視覚化できます。

  • Ambassador を使用してカナリアロールアウトを行うことができるため、サービスの新しいバージョンの影響を把握できます。

スナップショット

セットアップ

Agent Daemonset で DogStatsD を有効にし、Ambassador ポッドで次の環境変数を設定します。

name: STATSD_HOST
valueFrom:
  fieldRef:    
    fieldPath: status.hostIP

この設定では、StatsD メトリクスがホストの IP に送信され、トラフィックが Agent ポート 8125 にリダイレクトされます。

詳細については、Ambassador に関するドキュメントを参照してください。
