Hello,

This might be a vague question, so please bare with me. I am trying to integrate APM with our current distributed tracing stack involving Spring Cloud Sleuth. Essentially, I registered an OpenTracing tracer bean which uses the `ElasticApmTracer` instance; however, it seems as though Sleuth and the APM tracers are working independently and so I observe different trace/span ids for the same micro-service request.

My question is, is there any docs I could be pointed to that somewhat hint at how to accomplish should a task of incorporating say a current distributed tracing tool like Sleuth with APM so that they both are in synergy?

Thanks

Hi and welcome to the forum 🙂

This is probably due to the fact that Elastic APM and Sleuth use different headers to propagate the context. IIRC, Sleuth uses B3 headers, whereas Elastic APM uses `elastic-apm-traceparent` which is a variant of the W3C spec draft for the `traceparent` header.

See [https://github.com/elastic/apm/issues/116](https://github.com/elastic/apm/issues/116) for more information.
