unable to get any auto instrumentation to work for a GRPC server written in python

[kant777]

Hi All,

I am unable to get the auto instrumentation to work for the following server written in python https://github.com/lightstep/hipster-shop/blob/master/src/emailservice/email_server.py

I ran the server using the following command

opentelemetry-instrument --traces_exporter console python3 email_server.py

I was successfully able to invoke the server using https://github.com/lightstep/hipster-shop/blob/master/src/emailservice/email_client.py and I can see the requests hitting the server successfully as well however no spans had been generated not sure what else I need to do to see some spans?

Reproduced. Only jinja spans were generated and there were no grpc spans. I tested with latest 1.6.2 and 0.25b2

can you share the sample of jinja spans? Also do you know why grpc spans are not generated?

I don't know why. It looked like the instrumented tracing interceptor was not being called by grpc. Needs more investigation.

can you please provide steps you took to produce this jinja span?

I just ran the example you shared with otel packages version mentioned in this comment
