Datadog 클러스터 에이전트

Supported OS Mac OS Windows

통합 버전5.4.0

개요

본 점검은 Datadog 에이전트로 Datadog 클러스터 에이전트를 모니터링합니다.

설정

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

설치

Datadog 클러스터 에이전트 점검은 Datadog 에이전트 패키지에 포함됩니다. 서버에 추가 설치할 필요가 없습니다.

구성

Datadog 클러스터 에이전트 점검은 대부분의 시나리오에서 자동탐지 기능으로 자동으로 자체 설정됩니다. 점검은 클러스터 에이전트 포드와 동일한 노드의 Datadog 에이전트 포드에서 실행됩니다. 클러스터 에이전트 자체에서는 실행되지 않습니다.

점검을 추가로 설정해야 하는 경우:

  1. 에이전트의 설정 디렉토리의 루트에 있는 conf.d/폴더의 datadog_cluster_agent.d/conf.yaml 파일을 편집하여 datadog_cluster_agent 성능 데이터 수집을 시작합니다. 사용 가능한 모든 설정 옵션은 datadog_cluster_agent.d/conf.yaml 샘플을 참조하세요.

  2. 에이전트를 재시작하세요.

검증

에이전트의 상태 하위 명령을 실행하고 점검 섹션에서 datadog_cluster_agent를 검색합니다.
