AWS Step Functions

개요

AWS Step Functions로 시각적 워크플로우를 사용하여 분산 애플리케이션 및 마이크로서비스의 구성 요소를 조정할 수 있습니다.

이 통합을 활성화하면 Datadog에서 모든 Step Functions 메트릭을 볼 수 있습니다.

Datadog의 기본 AWS Step Function 모니터링 기능은 공개 베타 버전으로 제공됩니다. Step Functions를 향상된 메트릭 및 트레이스로 계측하려면 서버리스 문서 를 참조하세요.

설정

설치

아직 설정하지 않았다면 먼저 Amazon Web Services 통합을 설정합니다. 그 다음 아래의 권한을 AWS/Datadog 역할에 맞는 정책 문서에 추가합니다.

states:ListStateMachines,
states:DescribeStateMachine

메트릭 수집

AWS 통합 페이지에서 Metric Collection 탭 하단에 States이 활성화되어 있는지 확인합니다. 상태 시스템이 AWS Lambda를 사용하는 경우 Lambda도 체크되어 있는지 확인합니다.
Datadog - AWS Step Functions 통합을 설치합니다.

AWS Lambda 메트릭 보강

스텝 함수 상태가 Lambda 함수라면 본 통합 설치 시 Lambda 메트릭에 추가 statemachinename, statemachinearn, stepname 태그가 추가됩니다. Lambda 함수가 어떤 상태 시스템에 속하는지 확인할 수 있으며 서버리스 페이지에서 시각화할 수도 있습니다.

향상된 메트릭 수집

Datadog은 또한 개별 단계 지속 시간의 평균 또는 p99를 추적하는 데 도움이 되는 Step Functions에 대한 메트릭을 생성할 수 있습니다. AWS Step Functions에 대한 향상된 메트릭을 수집하려면 Datadog APM을 사용해야 합니다.

로그 수집

CloudWatch에 로그를 전송하도록 AWS Step Functions를 구성합니다. 참고: Datadog의 기본 CloudWatch 로그 그룹 접두사 /aws/vendedlogs/states를 사용하여 로그 소스를 식별하고 자동으로 파싱합니다.
Datadog에 로그를 전송합니다.

트레이스 수집

Step Functions용 Datadog APM 또는 AWS X-Ray를 통해 트레이스 수집을 활성화할 수 있습니다.

AWS Step Functions용 Datadog APM을 통해 추적 활성화

이 기능은 공개 베타 버전입니다.

AWS Step Functions에 대한 분산 추적을 활성화하려면 [서버리스 문서][9]의 설치 지침을 참조하세요.

AWS X-Ray를 통한 추적 활성화

이 옵션은 AWS Step Functions에 대한 향상된 메트릭을 수집하지 않습니다. 이러한 메트릭의 경우 AWS Step Functions용 Datadog APM을 통해 추적을 활성화해야 합니다.

AWS X-Ray를 통해 AWS Step Functions에서 트레이스를 수집하려면 다음을 수행합니다.

Datadog AWS X-Ray 통합을 활성화합니다.
AWS 콘솔에 로그인합니다.
Step Functions를 찾습니다.
Step Functions 중 하나를 선택하고 Edit을 클릭합니다.
페이지 하단의 Tracing 섹션으로 스크롤하여 Enable X-Ray tracing 상자에 체크 표시합니다.
권장 사항: 더 상세한 추적을 위해 함수에서 AWS X-Ray 추적 라이브러리를 설치하세요.
