Redis용 Google Cloud Memorystore

개요

Redis용 Google Cloud Memorystore는 확장 가능하고 안전하며 가용성 높은 인프라스트럭처에 구축된 완전관리형 인메모리 데이터 스토어 서비스를 제공합니다.

Datadog Google Cloud Platform 통합을 사용하여 Redis용 Google Cloud Memorystore에서 메트릭을 수집합니다.

설정

설치

아직 설치하지 않았다면 먼저 Google 클라우드 플랫폼 통합을 설정합니다. 그 외 다른 설치가 필요하지 않습니다.

로그 수집

Google Cloud Memorystore Redis 로그는 Google Cloud Logging으로 수집하여 클라우드 Pub/Sub 토픽을 통해 데이터 플로우 작업으로 전송됩니다. 아직 설정하지 않았다면 Datadog 데이터 플로우 템플릿으로 로깅을 설정하세요.

해당 작업이 완료되면 Google Cloud Logging에서 Google Cloud Memorystore Redis 로그를 다음 Pub/Sub 주제로 내보냅니다.

  1. Google Cloud Logging 페이지로 이동해 Google Cloud Memorystore Redis 로그를 필터링하세요.
  2. Create Export를 클릭하고 싱크 이름을 지정하세요.
  3. “Cloud Pub/Sub"를 대상으로 선택하고 해당 목적으로 생성된 Pub/Sub 주제를 선택합니다. 참고: Pub/Sub 주제는 다른 프로젝트에 있을 수 있습니다.
  4. Create를 클릭하고 확인 메시지가 나타날 때까지 기다립니다.
