What is the worker class you are using with gunicorn? Worker classes like gevent, eventler are not supported by otel-py sdk. Are you using the otel operator to auto instrument? The operator doesn't support the grpc https://github.com/open-telemetry/opentelemetry-operator/blob/main/autoinstrumentation/python/requirements.txt#L2. All of these issues are more related to otel than signoz

because of compatible issue with boto3 lib, I used below , so what I should change ? last time I used below but 0.28b0, and change to 4318 port as you guided it is working @Srikanth Chekuri

opentelemetry-distro==0.27b0
opentelemetry-instrumentation==0.27b0
opentelemetry-exporter-otlp==1.9.0

There are many things at play. What is the worker class you are using wit gunicorn?

work class is gevent @Srikanth Chekuri

It is not (probably will not be) supported by opentelemetry-python

do we have those compatible doc can be referenced in order to avoid this issue ? and what your suggested use for work class ? gthread?eventlet?

I don't think it is mentioned anywhere in http://opentelemetry-python.readthedocs.io

I dont see that in above link

What do you not see?

I didnt' see any work class mentioned

sync
eventlet
gevent 
tornado 
gthread

There is no python std worker class. I think it works with sync or tornado.

OK I 'll check , thanks

You are mixing up lot of stuff. This is not an issue with collector and it has nothing to do with grpc. gevent is does some magical stuff by monkey patching and doesn't play well with context propagation so that is what the not-supported means.

got it. thanks
