W3C Trace Context support in traced calls?

[fightingmonk]

Howdy @nirga . I've started using traceloop to instrument langchain workflows and have this question:

does OpenLLMetry inject traceparent headers into http calls out to OpenAI?

I assumed it would but I don't see any evidence of W3C Trace Context headers. Am I doing it wrong, or is this a FR?

I did a couple of searches and I can't find any mention of this issue.

Here's the reason this matters to me: I use a proxy in front of OpenAI that handles data provenance, PII detection, and some proprietary business-specific data tracking. It participates in distributed traces and sends Spans to my Otel collector. Linking those spans back to the application trace of course requires it get atraceparent header. So if I'm using a tracing solution in my application it needs to play nice and include trace context headers in any outbound network requests.

Hey @fightingmonk! Since we're using OpenTelemetry, it should play nice with the rest of your app. Reg. injecting the headers I'm not a 100% sure, but I assume it should since we're basically creating a new span for every call out to OpenAI

Thanks @nirga, helpful info.
