AWS XRay wrong service map when using OpenFeign with AppMesh and AWS Service Discovery

Question

I'm testing interservice communication with Spring Boot Rest services deployed on AWS with AppMesh and Service Discovery enabled. To be able to send messages from service a to service b I've to use the OpenFeign client to generate a proxy class.

Tech Stack

• Spring Boot OpenFeign
• AWS XRay
• ECS
• ECR
• Sleuth
• AppMesh (Virtual Node, Virtual Service)
• AWS Service Discovery (instead of Eureka)

Expected Behavior

In AWS XRay, it should show a call trace:

Client -> ServiceA -> ServiceB

Actual Behavior

In AWS XRay, I can see the call traces:

Client -> ServiceA Client -> ServiceB

Another question would be how to tell OpenFeign to use the HttpClient from AWS SDK?

I was able to fix this issue by using a dynamicNamingStrategy in tracingFilter

@Bean
  public Filter tracingFilter(final AWSXRayRecorder awsxRayRecorder) {

    log.info("Setting up AWS Xray tracing filter");
    return new AWSXRayServletFilter(SegmentNamingStrategy.dynamic(Optional.ofNullable(AWS_XRAY_SEGMENT_NAME).orElse(
        "xray-filter")));
  }

And create an HttpClientBuilder bean.

@Bean
  public HttpClientBuilder xrayHttpClientBuilder() {

    log.info("Setting up AWS xray http client configuration");
    return HttpClientBuilder.create();
  }

AWS XRay should now show the HTTP requests in the trace:
