Google 앱 엔진

개요

프로젝트에 Google 앱 엔진 통합을 설치합니다.

  • 멤캐시, 작업 대기열, 데이터 저장소 등 Google 앱 엔진 서비스 메트릭을 확인합니다.
  • 백분위수, 레이턴시, 비용 표시 등 요청에 대한 메트릭을 확인합니다.
  • Google 앱 엔진 메트릭에 버전별 태그를 설정하고 다양한 버전의 성능을 비교하세요.

API 또는 DogStatsD를 사용해 Datadog으로 커스텀 메트릭을 전송할 수도 있습니다.

설정

설치

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

로그 수집

Google 앱 엔진 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 앱 엔진 로그를 다음 Pub/Sub 주제로 내보냅니다.

  1. Google Cloud Logging 페이지로 이동해 Google 앱 엔진 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.
