개요

Datadog Agent는 다음을 포함하여 Consul 노드에서 많은 메트릭을 수집합니다.

  • Consul 피어 총개수
  • 서비스 상태 - 특정 서비스에 대해 UP, PASSING, WARNING, CRITICAL인 노드 수
  • 노드 상태 - 특정 노드에 대해 UP, PASSING, WARNING, CRITICAL인 서비스 수
  • 네트워크 좌표 - 데이터 센터 간 및 데이터 센터 내 대기 시간

Consul Agent는 DogStatsD를 통해 추가 메트릭을 제공할 수 있습니다. 이러한 메트릭은 Consul에 의존하는 서비스가 아닌 Consul 자체의 내부 상태와 더 관련이 있습니다. 메트릭은 다음과 같습니다.

  • Serf 이벤트 및 멤버 플랩
  • Raft 프로토콜
  • DNS 성능

이외에 다수가 있습니다.

Datadog Agent는 메트릭 외에도 Consul의 각 상태 점검마다 서비스 점검을 전송하고, 새 리더 선출마다 이벤트를 전송합니다.

설정

설치

Datadog Agent의 Consul 점검은 Datadog Agent 패키지에 포함되어 있으므로 Consul 노드에 다른 것을 설치할 필요가 없습니다.

구성

호스트

호스트에서 실행 중인 에이전트에 대해 이 점검을 구성하려면:

메트릭 수집
  1. Consul 메트릭 수집을 시작하려면 Agent의 설정 디렉터리 루트의 conf.d/ 폴더에서 consul.d/conf.yaml 파일을 편집합니다. 사용 가능한 모든 설정 옵션은 샘플 consul.d/conf.yaml을 참조하세요.

    init_config:
    
    instances:
      ## @param url - string - required
      ## Where your Consul HTTP server lives,
      ## point the URL at the leader to get metrics about your Consul cluster.
      ## Use HTTPS instead of HTTP if your Consul setup is configured to do so.
      #
      - url: http://localhost:8500
    
  2. 에이전트를 재시작합니다.

OpenMetrics

(선택 사항) use_prometheus_endpoint 설정 옵션을 활성화하여 Consul Prometheus 엔드포인트에서 추가 메트릭 세트를 가져올 수 있습니다.

참고: 동일한 인스턴스에 대해 두 가지를 모두 활성화하지 말고 DogStatsD 또는 Prometheus 메서드를 사용하세요.

  1. Prometheus 엔드포인트에 메트릭을 노출하도록 Consul을 설정합니다. 기본 Consul 설정 파일의 최상위 telemetry 키에 중첩된 prometheus_retention_time을 설정합니다.

    {
      ...
      "telemetry": {
        "prometheus_retention_time": "360h"
      },
      ...
    }
    
  2. Prometheus 엔드포인트 사용을 시작하려면 Agent의 설정 디렉터리 루트에 있는 conf.d/ 폴더에서 consul.d/conf.yaml 파일을 편집합니다.

    instances:
        - url: <EXAMPLE>
          use_prometheus_endpoint: true
    
  3. 에이전트를 재시작합니다.

DogStatsD

Prometheus 엔드포인트를 사용하는 대신 DogStatsD를 통해 동일한 추가 메트릭 세트를 Agent에 보내도록 Consul을 설정할 수 있습니다.

  1. DogStatsD 메트릭을 보내도록 Consul을 설정하려면 Consul의 기본 설정 파일에서 최상위 telemetry 키 아래에 중첩된 dogstatsd_addr을 추가합니다.

    {
      ...
      "telemetry": {
        "dogstatsd_addr": "127.0.0.1:8125"
      },
      ...
    }
    
  2. 메트릭에 태그가 올바르게 지정되었는지 확인하려면 다음 설정을 추가하여 Datadog Agent 기본 설정 파일 datadog.yaml을 업데이트합니다.

    # dogstatsd_mapper_cache_size: 1000  # default to 1000
    dogstatsd_mapper_profiles:
      - name: consul
        prefix: "consul."
        mappings:
          - match: 'consul\.http\.([a-zA-Z]+)\.(.*)'
            match_type: "regex"
            name: "consul.http.request"
            tags:
              method: "$1"
              path: "$2"
          - match: 'consul\.raft\.replication\.appendEntries\.logs\.([0-9a-f-]+)'
            match_type: "regex"
            name: "consul.raft.replication.appendEntries.logs"
            tags:
              peer_id: "$1"
          - match: 'consul\.raft\.replication\.appendEntries\.rpc\.([0-9a-f-]+)'
            match_type: "regex"
            name: "consul.raft.replication.appendEntries.rpc"
            tags:
              peer_id: "$1"
          - match: 'consul\.raft\.replication\.heartbeat\.([0-9a-f-]+)'
            match_type: "regex"
            name: "consul.raft.replication.heartbeat"
            tags:
              peer_id: "$1"
    
  3. 에이전트를 재시작합니다.

로그 수집

Agent 버전 6.0 이상에서 사용 가능

  1. 로그 수집은 Datadog Agent에서 기본적으로 비활성화되어 있습니다. datadog.yaml에서 다음을 사용하여 활성화합니다.

    logs_enabled: true
    
  2. Consul 로그를 수집하려면 consul.yaml 파일에서 이 설정 블록을 편집합니다.

    logs:
      - type: file
        path: /var/log/consul_server.log
        source: consul
        service: myservice
    

    pathservice 파라미터 값을 변경하고 환경에 맞게 구성합니다. 사용 가능한 모든 설정 옵션은 샘플 consul.d/conf.yaml을 참조하세요.

  3. 에이전트를 재시작합니다.

컨테이너화

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

메트릭 수집
파라미터
<INTEGRATION_NAME>consul
<INIT_CONFIG>비어 있음 또는 {}
<INSTANCE_CONFIG>{"url": "https://%%host%%:8500"}
로그 수집

Agent 버전 6.0 이상에서 사용 가능

Datadog 에이전트에서 로그 수집은 기본값으로 비활성화되어 있습니다. 이를 활성화하려면 쿠버네티스(Kubernetes) 로그 수집을 참조하세요.

파라미터
<LOG_CONFIG>{"source": "consul", "service": "<SERVICE_NAME>"}

검증

Agent의 상태 하위 명령을 실행하고 Checks 섹션에서 consul을 찾으세요.

참고: Consul 노드에 디버그 로깅이 활성화된 경우 Datadog Agent의 정기적인 폴링이 Consul 로그에 표시됩니다.
