Envoy

Supported OS Linux Windows Mac OS

통합 버전3.5.1

개요

이 검사는 Envoy에서 분산 시스템 옵저버빌리티 메트릭을 수집합니다.

설정

설치

Envoy 검사는 Datadog Agent 패키지에 포함되어 있으므로 서버에 다른 것을 설치할 필요가 없습니다.

Istio

Istio의 일부로 Envoy를 사용하는 경우 Istio 프록시 메트릭 엔드포인트에서 메트릭을 수집하도록 Envoy 통합을 구성합니다.

instances:
  - openmetrics_endpoint: localhost:15090/stats/prometheus

표준

/stats 엔드포인트를 설정하는 방법에는 두 가지가 있습니다.

보안되지 않은 통계 엔드포인트

다음은 Envoy 어드민 구성의 예입니다.

admin:
  access_log_path: "/dev/null"
  address:
    socket_address:
      address: 0.0.0.0
      port_value: 8001
보안된 통계 엔드포인트

어드민 엔드포인트(Envoy가 자체적으로 연결됨)로 라우팅하는 리스너/가상호스트를 생성합니다. 단, /stats에 대해서만 경로가 있으며 다른 모든 경로는 정적/오류 응답을 받습니다. 또한, 예를 들어 인증용 L3 필터와도 잘 통합할 수 있습니다.

다음은 envoy_secured_stats_config.json의 구성 예시입니다.

구성

    호스트

    호스트에서 실행 중인 에이전트에 대해 이 점검을 구성하려면:

    메트릭 수집

    1. Agent 구성 디렉터리의 루트에 있는 conf.d/ 폴더에서 envoy.d/conf.yaml 파일을 편집하여 Envoy 성능 데이터 수집을 시작하세요. 사용 가능한 모든 구성 옵션은 샘플 envoy.d/conf.yaml을 참조하세요.

      init_config:

instances:
    ## @param openmetrics_endpoint - string - required
    ## The URL exposing metrics in the OpenMetrics format.
    #
  - openmetrics_endpoint: http://localhost:8001/stats/prometheus

    2. Datadog Agent가 Envoy의 어드민 엔드포인트에 액세스할 수 있는지 확인하세요.

    3. Agent를 재시작합니다.

    로그 수집

    Agent 버전 6.0 이상에서 사용 가능

    1. Datadog 에이전트에서 로그 수집은 기본적으로 사용하지 않도록 설정되어 있습니다. datadog.yaml파일에서 로그 수집을 사용하도록 설정합니다.

      logs_enabled: true

    2. 다음으로, 맨 아래 logs 줄의 주석 처리를 제거하여 envoy.d/conf.yaml을 편집합니다. Envoy 로그 파일의 올바른 경로로 로그 path를 업데이트합니다.

      logs:
  - type: file
    path: /var/log/envoy.log
    source: envoy
    service: envoy

    3. Agent를 재시작합니다.

    컨테이너화

    컨테이너화된 환경의 경우 자동탐지 통합 템플릿에 다음 파라미터를 적용하는 방법이 안내되어 있습니다.

    메트릭 수집
    파라미터값
    <INTEGRATION_NAME>envoy
    <INIT_CONFIG>비어 있음 또는 {}
    <INSTANCE_CONFIG>{"openmetrics_endpoint": "http://%%host%%:80/stats/prometheus"}
    참고: 검사의 현재 버전(1.26.0+)은 메트릭 수집을 위해 OpenMetrics를 사용하며, Python 3이 필요합니다. Python 3을 사용할 수 없는 호스트의 경우 또는 이 검사의 레거시 버전을 사용하려면 다음 구성을 참조하세요.
    로그 수집

    Agent 버전 6.0 이상에서 사용 가능

    Datadog Agent에서는 로그 수집이 기본적으로 비활성화되어 있습니다. 활성화하려면 Kubernetes 로그 수집을 참조하세요.

    파라미터값
    <LOG_CONFIG>{"source": "envoy", "service": "<SERVICE_NAME>"}

    검증

    Agent의 상태 하위 명령을 실행하고 Checks 섹션에서 envoy를 찾습니다.

    일반적인 문제

    엔드포인트 /server_info에 연결할 수 없음

    • Envoy 환경에서 엔드포인트를 사용할 수 없는 경우 Envoy 구성에서 collect_server_info 옵션을 비활성화하여 오류 로그를 최소화합니다.

    참고: Envoy 버전 데이터는 수집되지 않습니다.
