Amazon DynamoDB

DynamoDB 기본 대시보드

개요

Amazon DynamoDB는 AWS 포트폴리오의 일부인 완전관리형 NoSQL 데이터베이스 클라우드 서비스입니다. 빠르고 쉽게 확장할 수 있으며 대규모 데이터를 처리하는 중에도 매우 낮은 지연을 요구하는 애플리케이션을 지원할 수 있습니다. 문서 및 핵심-값 저장 모델을 모두를 지원하며 데이터베이스 및 분산된 해시 표 등 속성을 제공합니다.

설정

설치

아직 설치하지 않으셨다면, Amazon Web Services 통합을 먼저 설치하시기 바랍니다.

메트릭 수집

  1. AWS 통합 페이지에서 Metric Collection 탭에 DynamoDB가 활성화되어 있습니다.

  2. Amazon DynamoDB 메트릭를 수집하려면 Datadog IAM 정책에 이러한 권한을 추가합니다.

    • dynamodb:ListTables: 사용 가능한 DynamoDB 표를 목록화하는 데 사용됩니다.
    • dynamodb:DescribeTable: 메트릭을 표 크기 또는 항목 개수로 추가할 수 있습니다.
    • dynamodb:ListTagsOfResource: DynamoDB 리소스에서 태그를 모두 수집하는 데 사용됩니다.

    자세한 내용은 AWS 웹사이트의 DynamoDB 정책을 참조하세요.

  3. Datadog - Amazon DynamoDB 통합을 설치합니다.

로그 수집

로깅 활성화

AWS CloudTrail에서 트레일을 생성한 다음 기록을 작성할 S3 버킨을 선택합니다.

Datadog에 로그 보내기

  1. 아직 설정하지 않았다면 AWS 계정에서 Datadog 포워더 람다 함수를 설정하세요.
  2. 설정한 후에는 Datadog Forwarder Lambda 함수로 이동하세요. Function Overview 섹션에서 Add Trigger를 클릭합니다.
  3. 트리거 설정에 대해 S3 트리거를 선택합니다.
  4. Amazon DynamoDB가 포함된 S3 버킷을 선택합니다.
  5. 이벤트 유형을 All object create events로 남겨둡니다.
  6. Add를 클릭해 Lambda에 트리거를 추가합니다.

로그 탐색기로 이동해 로그를 살펴보기 시작합니다.

AWS 서비스 로그 수집에 대한 자세한 내용은 , Datadog 람다 함수에 포함된 AWS 서비스 로그 전송]를 참조하세요.
