Disable Xray feature on local dev machine(Java Spring boot AOP project)

Question

HI,  
I have a spring boot application (2.3.1) running in a AWS EC2 instance. I followed AWS documentation for Spring and AOP:https://docs.aws.amazon.com/xray/latest/devguide/xray-sdk-java-aop-spring.html  
I am able to see the traces and service map after I deploy on my AWS EC2 instance.  
But when I run my code on my local machine in dev environment(NOT on EC2), it throws an error.

Questions:  
1.) We do not need the traces to be generated and sent to aws. How do we TURN OFF/DISABLE Xray tracing feature on our dev machines ?

Answer

Hello,  
  
For context, this is happening because the daemon is not running in your dev environment and so the SDK cannot contact it to retrieve centralized sampling rules. Disabling the SDK a known feature request that we have in our backlog, we hope to add support for an environment variable that can disable the SDK soon: https://github.com/aws/aws-xray-sdk-java/issues/178  
  
As a workaround, you could have your own development environment variable and set the sampling strategy to a no-op strategy using it:  
  
AWSXRayRecorderBuilder builder = AWSXRayRecorderBuilder.standard();  
if (inDevEnvironment) {  
    builder.withSamplingStrategy(new NoSamplingStrategy());  
}
