We are pleased to announce support for request tracing, a unique identifier appended to the HTTP header of each request processed by an Application Load Balancer. This allows for each request to be uniquely identified, providing improved monitoring and request-level diagnostics.
A unique request identifier allows you to trace a single request across various services that make up your website and distributed applications. By preserving the trace header across services that make up your application, you can uncover any issues and identify performance bottlenecks in your application stack at the granularity of an individual request.
All Application Load Balancers now offer support for request tracing. Learn more by visiting http://docs.aws.amazon.com/elasticloadbalancing/latest/application/load-balancer-request-tracing.html
