Amazon EMR

개요

Amazon EMR는 대량의 데이터를 쉽고 빠르며 비용 효율적으로 처리할 수 있게 도와드리는 웹 서비스입니다.

본 통합을 활성화하여 Datadog에서 EMR 메트릭을 확인하세요.

설정

설치

아직 설정하지 않은 경우 먼저 Amazon Web Services 통합을 설정하세요.

메트릭 수집

  1. AWS 통합 페이지에서 Metric Collection 탭의 EMR이 활성화되어 있는지 확인하세요.

  2. Amazon EMR 메트릭을 수집하려면 다음 권한을 Datadog IAM 정책에 추가합니다. 자세한 정보는 AWS 웹사이트의 EMR 정책을 참조하세요.

    AWS 권한설명
    elasticmapreduce:ListClusters이용 가능한 클러스터 목록.
    elasticmapreduce:DescribeCluster클라우드와치(CloudWatch) EMR 메트릭에 태그 추가.

  3. Datadog - Amazon EMR 통합을 설치하세요.

로그 수집

로깅 활성화

Amazon EMR를 설정하여 S3 버킷 또는 클라우드와치(CloudWatch) 중 하나로 로그를 전송합니다.

참고: S3 버킷에 로깅하는 경우 amazon_emr이 대상 접두어( Target prefix)로 설정되어 있는지 확인하세요.

Datadog에 로그 전송

  1. 이미 하지 않은 경우 Datadog 포워더 람다 함수를 설정하세요.

  2. 람다 함수가 설치되면 AWS 콘솔에서 Amazon EMR 로그를 포함하는 S3 버킷 또는 클라우드와치(CloudWatch) 로그 그룹에 수동 트리거를 추가합니다.
