Oracle 대시보드

개요

Oracle 통합은 Oracle 데이터베이스 상태 및 성능 메트릭을 거의 실시간으로 제공합니다. 제공된 대시보드를 사용하여 이러한 메트릭을 시각화하고 모니터링을 생성하여 팀에 Oracle 데이터베이스 상태를 알릴 수 있습니다.

데이터베이스 모니터링(DBM)을 활성화하면 쿼리 성능 및 데이터베이스 상태에 대한 향상된 인사이트를 얻을 수 있습니다. 표준 통합 기능과 더불어 Datadog DBM은 쿼리 수준 메트릭, 실시간 및 과거 쿼리 스냅샷, 대기 이벤트 분석, 데이터베이스 로드, 쿼리 설명 플랜, 차단 쿼리 인사이트 등을 제공합니다.

설치

사전 요구 사항

Oracle 통합을 사용하려면 기본 클라이언트(추가 설치 단계 필요 없음)나 Oracle 인스턴트 클라이언트를 사용합니다.

Oracle 인스턴트 클라이언트

인스턴트 클라이언트를 사용하지 않는 경우 이 단계를 건너뛰세요.

    Linux

    1. Linux용 Oracle 인스턴트 클라이언트 설치 지침을 따릅니다.

    2. 인스턴트 클라이언트 베이직 패키지가 설치되어 있는지 확인합니다. Oracle의 다운로드 페이지에서 찾을 수 있습니다.

      인스턴트 클라이언트 라이브러리를 설치한 후 다음 예시처럼 런타임 링커가 해당 라이브러리를 찾을 수 있는지 확인합니다.

      # Put the library location in the /etc/datadog-agent/environment file.

echo "LD_LIBRARY_PATH=/u01/app/oracle/product/instantclient_19" \
>> /etc/datadog-agent/environment
    Windows

    1. Oracle 윈도우즈(Windows) 설치 지침에 따라 Oracle 인스턴트 클라이언트를 설정합니다.

    2. 다음을 확인합니다.

      • Microsoft Visual Studio 2017 Redistributable 또는 해당 버전이 Oracle 인스턴트 클라이언트에 설치되어 있습니다.

      • Oracle의 다운로드 페이지에서 인스턴트 클라이언트 베이직 패키지가 설치되어 있으며, 해당 머신의 모든 사용자가 사용할 수 있습니다(예: C:\oracle\instantclient_19).

      • PATH 환경변수에는 인스턴트 클라이언트(예: C:\oracle\instantclient_19)가 있는 디렉토리가 포함됩니다.

      설정

      호스트에서 실행 중인 에이전트에 대해 이 점검을 구성하려면:

      1. 에이전트 설정 디렉토리의 루트에 있는 conf.d/ 폴더에서 oracle.d/conf.yaml 파일을 편집합니다. server 및 port를 업데이트하여 마스터가 모니터링하도록 설정합니다. 사용 가능한 모든 설정 옵션을 확인하려면 oracle.d/conf.yaml 샘플을 참조하세요.

        init_config:

instances:
   ## @param server - string - required
   ## The IP address or hostname of the Oracle Database Server.
   #
   - server: localhost:1521

     ## @param service_name - string - required
     ## The Oracle Database service name. To view the services available on your server,
     ## run the following query: `SELECT value FROM v$parameter WHERE name='service_names'`
     #
     service_name: <SERVICE_NAME>

     ## @param username - string - required
     ## The username for the Datadog user account.
     #
     username: <USERNAME>

     ## @param password - string - required
     ## The password for the Datadog user account.
     #
     password: <PASSWORD>

      참고: 7.50.1(포함)과 7.53.0(제외) 사이의 에이전트 릴리즈의 경우 설정 하위 디렉토리는 oracle-dbm.d입니다. 다른 모든 에이전트 릴리스의 경우 설정 디렉토리는 oracle.d입니다.

      참고: 에이전트는 V$ 뷰를 쿼리하여 모든 노드에서 개별적으로 정보를 수집하므로, Oracle Real Application 클러스터(RAC) 고객은 각 RAC 노드에 대해 에이전트를 설정해야 합니다. 에이전트 쿼리는 상호 연결 트래픽을 생성하지 않도록 GV$ 보기를 쿼리하지 않습니다.

      1. 에이전트를 재시작하세요.

      TCPS를 통해 Oracle에 연결

      TCPS(SSL을 사용한 TCP)를 통해 Oracle에 연결하려면 protocol 설정 옵션의 주석을 해제하고 TCPS를 선택합니다. server 옵션을 업데이트하여 TCPS 서버가 모니터링하도록 설정합니다.

      ```yaml
init_config:

instances:
  ## @param server - string - required
  ## The IP address or hostname of the Oracle Database Server.
  #
  - server: localhost:1522

    ## @param service_name - string - required
    ## The Oracle Database service name. To view the services available on your server,
    ## run the following query:
    #
    service_name: "<SERVICE_NAME>"

    ## @param username - string - required
    ## The username for the user account.
    #
    username: <USER>

    ## @param password - string - required
    ## The password for the user account.
    #
    password: "<PASSWORD>"

    ## @param protocol - string - optional - default: TCP
    ## The protocol to connect to the Oracle Database Server. Valid protocols include TCP and TCPS.
    ##
    #
    protocol: TCPS
```

      검증

      에이전트의 상태 하위 명령을 실행하고 점검 섹션에서 oracle를 찾습니다.

      커스텀 쿼리

      커스텀 쿼리 제공도 지원됩니다. 각 쿼리는 다음과 같이 파라미터 두 개가 있어야 합니다.

      파라미터설명
      query실행할 SQL입니다. 간단한 문이나 여러 줄의 스크립트일 수 있습니다. 결과의 모든 행이 평가됩니다.
      columns각 열을 나타내는 목록이며, 왼쪽에서 오른쪽으로 순차 정렬됩니다. 다음 두 가지 데이터가 필요합니다.
      a. type - 제출 메소드(gauge, count 등)입니다.
      b. 이름 - 전체 메트릭 이름에 사용되는 접미사입니다. type가 tag인 경우 해당 열은 특정 쿼리에서 수집한 모든 메트릭에 적용되는 태그로 대신 간주됩니다.

      옵션으로 tags 파라미터를 사용하여 수집된 각 메트릭에 태그 목록을 적용할 수 있습니다.

      다음을 확인합니다.

      self.gauge('oracle.custom_query.metric1', value, tags=['tester:oracle', 'tag1:value'])
self.count('oracle.custom_query.metric2', value, tags=['tester:oracle', 'tag1:value'])

      다음 예제 설정은 아래와 같습니다.

      - query: | # Use the pipe if you require a multi-line script.
    SELECT columns
    FROM tester.test_table
    WHERE conditions
  columns:
    # Put this for any column you wish to skip:
    - {}
    - name: metric1
      type: gauge
    - name: tag1
      type: tag
    - name: metric2
      type: count
  tags:
    - tester:oracle

      사용 가능한 모든 설정 옵션은 oracle.d/conf.yaml 샘플를 참조하세요.
