Are you using it with

opentelemetry-instrument

command? If so, skip the

trace.set_tracer_provider(TracerProvider(resource=resource))

line.

Tried that as well. Then the last line fails:

trace.get_tracer_provider().add_span_processor(span_processor)

Are you just getting the

Overriding of current TracerProvider is not allowed

? or does it also not produce any telemetry? If it’s just a message then you can ignore it.

It was not producing telemetry also. I'll check again.

You can’t use

opentelemetry-instrument

and

post_fork

hook together because both of them try to set up the telemetry pipeline so use only one of them. If you are using the latest version of opentelemetry python SDK you may not need

post_fork

at all.

I see. I'll drop the post_fork in that case.
