As a developer, I'd like to be able to lookup traces for a given request based on the response headers. There is a draft standard for this, where the format is:

traceresponse: 00-$traceId-$spanId-$flags

where $flags is typically 01 to indicate the trace was sampled. There are other supported bits in the flags value, see https://w3c.github.io/trace-context/#version-format .

There are implementation hints in the related quarkus issue.

• https://github.com/quarkusio/quarkus/issues/11931

Done:

• A submodule exists in our project to enable this behavior
• All quarkus-based services configured to use the module
• A PR opened to contribute this functionality back to upstream quarkus, resolving the quarkus issue referenced above
