Couchbase 바이트 읽기

개요

분주한 버킷을 식별하고 캐시 실패율 등을 추적하세요. 이 에이전트 점검은 다음과 같은 메트릭을 수집합니다.

  • 데이터가 사용하는 하드 디스크 및 메모리
  • 현재 연결
  • 총 개체
  • 초당 운영
  • 디스크 작성 대기열 크기

이 외에도 더 많은 사항을 추적할 수 있습니다.

설정

설치

Couchbase 점검이 Datadog 에이전트 패키지에 포함되어 있으므로 Couchbase 노드에 아무 것도 설치할 필요가 없습니다.

설정

    호스트

    호스트에서 실행 중인 에이전트에 대해 이 점검을 구성하려면:

    메트릭 수집
    1. 에이전트의 설정 디렉터리 루트에 있는 conf.d/ 폴더에서 couchbase.d/conf.yaml 파일을 편집하여 Couchbase 데이터 수집을 시작하세요. 사용 가능한 모든 설정 옵션은 sample couchbase.d/conf.yaml을 참조하세요.
    init_config:

instances:
  ## @param server - string - required
  ## The server's url.
  #
  - server: http://localhost:8091
    1. 에이전트트 다시 시작합니다.

    로그 수집

    에이전트 버전 > 6.0 이상 사용 가능

    1. Datadog Agent에서는 로그 수집이 기본적으로 비활성화되어 있습니다. datadog.yaml 파일에서 활성화해야 합니다.

      logs_enabled: true

    2. 이 설정 블록을 couchbase.d/conf.yaml 파일에 추가하여 Couchbase 로그 수집을 시작하세요.

      logs:
  - type: file
    path: /opt/couchbase/var/lib/couchbase/logs/couchdb.log
    source: couchdb

      path 및 service 파라미터 값을 변경하고 환경에 맞게 설정하세요. 사용 가능한 모든 설정 옵션은 sample couchbase.d/conf.yaml을 참조하세요.

    3. Restart the Agent.

    컨테이너화된 환경

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

    메트릭 수집
    파라미터값
    <INTEGRATION_NAME>couchbase
    <INIT_CONFIG>비어 있음 또는 {}
    <INSTANCE_CONFIG>{"server": "http://%%host%%:8091"}

    검증

    에이전트의 상태 하위 명령을 실행하고 점검 섹션에서 couchbase를 찾습니다.
