Project: Send trace origin

[philipphofmann]

Description

Trace origin indicates what created a trace or a span. Not all traces and spans contain enough information to tell whether the user or what precisely in the SDK created it. Origin solves this problem. Origin can be sent with the trace context or spans. The SDKs must set this value automatically. It is not expected to be set manually by users. For more information, visit the develop docs. If the spec needs further clarification, you can ping @philipphofmann.

As origin for trace context and spans is optional, every SDK can decide whether to start sending origin for everything or just selected transactions and spans. This issue is important for internal data analysis to understand the quality of our traces; see internal Notion doc.

[HazAT]

Is there something like this in OTEL?

[philipphofmann]

@HazAT, I don't think so. When I wrote the RFC getsentry/rfcs#73, I checked the OTEL spec and didn't find anything similar, but I could be wrong as I'm not that familiar with the spec. @AbhiPrasad, as you quote OTEL regularly, do you know if something like the trace orign exists? I guess not cause you would have brought it up in getsentry/rfcs#73.

There is a somewhat similar HTTP header origin I used as a bit of inspiration for trace origin.
