AWS 람다

이 페이지는 Amazon 클라우드와치(CloudWatch)에서 AWS 람다 메트릭 수집을 위한 설명서로 제한됩니다. 실시간으로 람다 함수에서 직접 텔레메트리를 수집하기 위한 Datadog 서버리스 설명서를 참조하세요 .

개요

AWS 람다는 이벤트에 대응하기 위한 코드를 실행하고 자동으로 해당 코드에서 필요로 하는 컴퓨팅 리소스를 관리하는 컴퓨팅 서비스입니다.

클라우드와치(CloudWatch) 수집을 시작하려면 이 통합을 활성화하세요. 또한, 이 페이지에서 람다 함수를 위한 커스텀 메트릭, 로깅 및 추적을 설정하는 방법을 설명하세요.

이미 하지 않은 경우 먼저 Amazon Web Services 통합을 설정하세요.

메트릭 수집

AWS 람다 메트릭

  1. AWS 통합 페이지에서 Lambda가 Metric Collection 탭에서 활성화되어 있는지 확인하세요.

  2. Datadog IAM 정책에 다음 권한을 추가하여 AWS 람다 메트릭을 수집하세요. 자세한 정보는 AWS 웹사이트에서 람다 정책을 참조하세요.

    AWS 권한설명
    lambda:List*람다 함수, 메타데이터 및 태그를 목록화합니다.
    tag:GetResources람다 함수에 적용되는 커스텀 태그를 받습니다.
    cloudtrail:LookupEventsCloudTrail 기록을 사용하여 람다 함수에 대한 변경 사항을 탐지합니다.

완료되면 Datadog 서버리스 보기에서 람다 함수 전체를 봅니다. 이 페이지는 서버리스 애플리케이션이 실행되는 AWS 람다 함수에서 메트릭, 트레이스 및 로그를 수집해 단일 보기로 제공합니다. 이 기능에 대한 상세한 설명서를 Datadog 서버리스 설명서에서 찾아볼 수 있습니다.

수집한 데이터

AWS 람다 확장명을 사용하면 AWS에서 보고하는 기간 메트릭은 람다 함수가 소비하는 post_runtime_extensions_duration 보고하여 함수 반응을 반환한 뒤 활동을 수행합니다. . 함수의 실제 성능을 모니터링하려면 duration - post_runtime_extensions_duration 또는 Datadog 개선 메트릭 aws.lambda.enhanced.runtime_duration을 사용하세요.

AWS에서 검색한 각 메트릭에는 AWS 콘솔에 표시하는 동일한 태그가 할당되어 있습니다. 함수 이름, 보안-그룹 등을 포함하나 이에 제한되지 않습니다.
