Knowledge

• x-ray : Segments and subsegments

• Lambda : portal启用 / cloudformation启用

  Properties:
      TracingConfig:
          Mode: Active

• API Gateway : cloudformation启用

  ApiGatewayDeployment:
    Type: “AWS::ApiGateway::Deployment”
    Properties:
      StageDescription:
         TracingEnabled: true

  After this change API gateway will generate (if missing) and add X-Amzn-Trace-Id header to every incoming request

• x-ray issues：

  You cannot trace async operations

  Custom subsegments that you create are not visible on the node graph

  using it in the golang application requires a lot of additional work like wrapping HTTP or AWS clients and passing Context to every function.

• X-Ray cannot replace well-designed monitoring so it should be used as an additional tool to help debug the application, not as the main one.
