I have few services written in Node that are using "X-Request-Id" as the header to identify requests. I am now writing services in Java using spring-boot where I can use spring-cloud-sleuth to track traceId and spanId.

However, I would like to continue using the "X-Request-Id" as the request identifier across all of my services. Is there any way to rename the "X-B3-TraceId" header in spring-sleuth so that it sends the same header in HTTP requests and also uses the said header from incoming requests to set the traceId?

You can propagate extra fields, see the Propagation section of the Spring Cloud Sleuth docs.

  • With propagation I'll have to support multiple headers - the previous one that all my Node services are using as well as the "X-B3-TraceId" that spring sleuth adds. Is there no other way? – Pravesh Jain Dec 18 '20 at 15:28
