개요

Google Cloud Spanner는 강력한 일관성과 수평적 확장성을 전부 갖춘 최초이자 유일한 관계형 데이터베이스 서비스입니다.

Google Spanner 메트릭을 수집하면 다음을 할 수 있습니다.

Spanner 데이터베이스 성능을 가시화합니다.
Spanner 데이터베이스의 성능과 애플리케이션의 상관 관계를 파악합니다.

메트릭 수집

설치

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

로그 수집

Google Cloud Spanner 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 Spanner 로그를 다음 Pub/Sub 주제로 내보냅니다.

Google Cloud Logging 페이지로 이동해 Google Cloud Spanner 로그를 필터링하세요.
Create Sink를 클릭하고 그에 따라 싱크 이름을 지정합니다.
“Cloud Pub/Sub"를 대상으로 선택하고 해당 목적으로 생성된 Pub/Sub 주제를 선택합니다. 참고: Pub/Sub 주제는 다른 프로젝트에 있을 수 있습니다.
Create를 클릭하고 확인 메시지가 나타날 때까지 기다립니다.
