설정

Agent Daemonset에서 DogStatsD를 활성화하고 Ambassador Pod에서 다음 환경 변수를 설정합니다.

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

이 설정을 사용하면 StatsD 메트릭이 호스트의 IP로 전송되어 트래픽을 Agent 포트 8125로 리디렉션합니다.

자세한 내용은 StatsD를 사용한 Envoy 통계를 참조하세요.

또한 Ambassador에서 Datadog APM으로 추적 데이터를 보낼 수도 있습니다. 자세한 내용은 Datadog을 사용한 분산 추적을 참조하세요.
