아마존 EventBridge 및 AWS X-Ray
AWS X-Ray Amazon과 EventBridge 통합하여 EventBridge 전달된 이벤트를 추적합니다. X-Ray로 인스트루먼트된 서비스가 이벤트를 SDK 보내는 EventBridge 경우 추적 컨텍스트는 추적 헤더 내의 다운스트림 이벤트 대상으로 전파됩니다. X-Ray는 트레이싱 헤더를 SDK 자동으로 픽업하여 후속 계측기에 적용합니다. 이러한 연속성을 통해 사용자는 다운스트림 서비스 전반을 추적, 분석, 디버깅할 수 있으며 시스템을 보다 완벽하게 파악할 수 있습니다.
자세한 내용은 EventBridge 사용자 안내서의 EventBridge X-Ray 통합을 참조하십시오.
X-Ray 서비스 맵에서 소스 및 대상 보기
X-Ray trace 맵에는 다음 예와 같이 소스 서비스와 대상 서비스를 연결하는 EventBridge 이벤트 노드가 표시됩니다.

추적 컨텍스트를 이벤트 대상으로 전파하기
SDKX-Ray를 사용하면 EventBridge 이벤트 소스가 추적 컨텍스트를 다운스트림 이벤트 대상으로 전파할 수 있습니다. 다음 언어별 예제는 활성 추적이 활성화된 Lambda 함수에서의 호출을 EventBridge 보여줍니다.
