Supported OS Linux Windows Mac OS

통합 버전3.3.1

개요

이 점검에서는 Datadog 에이전트를 통해 IBM Webshpere Application Server(WAS)를 모니터링합니다. 이 점검은 IBM WAS 버전 >= 8.5.5를 지원합니다.

설정

아래 지침을 따라 호스트에서 실행되는 에이전트에 대해 이 점검을 설치하고 설정하세요. 컨테이너화된 환경의 경우 이러한 지침을 적용하는 데 가이드가 필요하면 오토파일럿 통합 템플릿을 참조하세요.

IBM WAS Datadog 통합에서는 WebSphere Application Server에서 활성화된 PMI 카운터를 가져옵니다. 설정하려면 Datdog가 WAS에서 성능 데이터를 가져올 수 있도록 PerfServlet을 활성화해야 합니다.

기본적으로 이 점검에서는 JDBC, JVM, 스레드 풀, Servlet Session Manager 메트릭을 수집합니다. “custom_queries” 섹션에서 더 수집하고 싶은 메트릭을 추가할 수 있습니다. 예시를 보려면 샘플 점검 구성을 참고하세요.

설치

IBM WAS 점검은 Datadog 에이전트 패키지에 포함되어 있습니다.

PerfServlet을 활성화하세요.

WebSphere Application Server 설치 경로가 <WAS_HOME>인 경우 <WAS_HOME>/installableApps 디렉터리에서 servlet’s .ear file(PerfServletApp.ear)을 찾을 수 있습니다.

성능 servlet은 다른 servlet과 동일한 방법으로 배포됩니다. 도메인 내 단일 애플리케이션 서버 인스턴스에 servlet을 배포하세요.

참고: 버전 6.1부터는 PerfServlet을 작동할 때 애플리케이션 보안을 활성화해야 합니다.

모니터링된 통계 세트 변경

기본적으로 애플리케이션 서버는 “Basic” 모니터링만 하도록 구성되어 있습니다. 내 JVM, JDBC, servlet 연결을 가시화하려면 내 애플리케이션 서버의 모니터링 중인 통계 세트를 “Basic"에서 “All"로 변경하세요.

Websphere Administration Console에서 Application servers > <YOUR_APP_SERVER> > Performance Monitoring Infrastructure (PMI)으로 이동해 설정을 찾을 수 있습니다.

변경한 후 “Apply"를 클릭해 구성을 저장하고 애플리케이션 서버를 재시작하세요. 변경 몇 분 후에 JDBC, JVM, servlet 메트릭이 Datadog에 추가로 나타나기 시작합니다.

구성

    호스트

    호스트에서 실행 중인 에이전트에 이 점검을 구성하는 방법:

    메트릭 수집

    1. 에이전트 구성 디렉터리 루트에 있는 conf.d/ 폴더에서 ibm_was.d/conf.yaml 파일을 편집하여 IBM WAS 성능 데이터를 수집하세요. 사용 가능한 모든 구성 옵션은 샘플 ibm_was.d/conf.yaml을 참고하세요.

    2. 에이전트를 재시작합니다.

    로그 수집

    에이전트 버전 > 6.0에서 사용 가능

    1. Datadog 에이전트에서 로그 수집은 기본적으로 사용하지 않도록 설정되어 있습니다. datadog.yaml 파일에서 로그 수집을 사용하도록 설하세요.

      logs_enabled: true

    2. 그 후 하단에 있는 logs 줄의 주석 처리를 제거하여 ibm_was.d/conf.yaml을 편집하세요. WAS 로그 파일의 올바른 경로로 로그 path를 업데이트합니다.

      logs:
  - type: file
    path: /opt/IBM/WebSphere/AppServer/profiles/InfoSphere/logs/server1/*.log
    source: ibm_was
    service: websphere

    3. 에이전트를 재시작합니다.

    컨테이너화된 환경

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

    메트릭 수집
    파라미터값
    <INTEGRATION_NAME>ibm_was
    <INIT_CONFIG>비어 있음 또는 {}
    <INSTANCE_CONFIG>{"servlet_url": "http://%%host%%:%%port%%/wasPerfTool/servlet/perfservlet"}
    로그 수집

    에이전트 버전 > 6.0에서 사용 가능

    Datadog 에이전트에서 로그 수집은 기본값으로 비활성화되어 있습니다. 이를 활성화하려면 쿠버네티스 로그 수집을 참고하세요.

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