OS: Debian 12
Python version: Any
Package version: 0.49b0 and later
What happened?
Since 1.28.0, the opentelemetry Python SDK supports exemplars. However some instrumentation libraries does not add exemplars because the measure are added/recorded outside of the active span.
For example, in the asgi instrumentation, all measures should be taken within the _usespan context rather than outside:
You can test the repository https://github.com/webscit/opentelemetry-demo-python with OTEL_AUTO_INSTRUMENTATION_LEVEL = 1, it uses fastapi instrumentation (but the flaw is actually in the asgi instrumentation).
Expected Result
Exemplars are recorded for all Python instrumentations
Actual Result
Some instrumentations are missing exemplars
Additional context
I don't know if all packages or only a subset of them are concerned by this. I have at least identified 3 cases:
