Will try to work on that during the next weekend.

Before jumping right into the code I have been studying the opentelemetry go API. Given that the notion of logs is not complete in opentelemetry yet but is something used in Jaeger, I wanted to make sure we have a strategy to migrate what is currently 'logged' in HotROD to what in opentelemetry is called an 'Event'. Is this a good understanding? The only other option in open telemetry is to use Attributes (key-value) which are what in jaeger-client we call Tags.

in the article there is also a section that describes the difference between tags vs Logs.

Let me clarify - at this time our intention is not to upgrade everything to OTEL API, but keep OT instrumentation and use OT-to-OTEL bridge to replace Jaeger SDK with OTEL SDK. Therefore your question is not relevant because that decision will be made by the bridge.

Copy that! I'm glad I asked the question! 😄

## Which problem is this PR solving? Since the HotROD UI does not start traces, it can only search for a trace corresponding to a particular request by some span tags. This makes the experience of opening a trace a big clunky as we first see the search page with one trace, and then have to click on the trace again. Related to #3380 ## Short description of the changes Change the HTTP instrumentation to always generate a `traceresponse` header per the [current W3C draft](https://github.com/w3c/trace-context/blob/main/spec/21-http_response_header_format.md). Then parse the trace ID from that header in the UI and generate a hyperlink to open the trace view directly, bypassing the search. --------- Signed-off-by: Yuri Shkuro <github@ysh.us>

The only remaining references to opentracing are in documentation files, still need to clean them up:
