@Prashant Shahi @Srikanth Chekuri @Ankit Nayan today I logged in sample-django-deployment-6fd7b76ccc-694gz pod to test my-release-signoz-otel-collector and my-release-signoz-otel-collector-metrics if working properly, and found the command mentioned in https://signoz.io/docs/instrumentation/python run successfully but seems no any data logged in otel-collector or otel-collector-metric , I can' t see any logs in otel-collector or otel-collector-metrics as well as the dashboard , but if I telnet those endpoint, it is working and shows the logs in both , can you help on that ? yesterday @Prashant Shahi helped to checked everything I deployed cannot find any issue but Signoz just can show any data in dashboard and didn't work properly.

My guess is that image was not built successfully with grpc. Can you configure the
OTEL_TRACES_EXPORTER=otlp_proto_http
and
OTEL_EXPORTER_OTLP_TRACES_ENDPOINT=<http://localhost:4318/v1/traces>
and see what happens
replace localhost with correct host

sure
@Srikanth Chekuri I just tried on simple python and check logs seems nothing changed
Copy code
DJANGO_SETTINGS_MODULE=mysite.settings  OTEL_RESOURCE_ATTRIBUTES=service.name=c10 OTEL_TRACES_EXPORTER=otlp_proto_http  OTEL_EXPORTER_OTLP_TRACES_ENDPOINT=<http://my-release-signoz-otel-collector:4317/v1/traces> opentelemetry-instrument --traces_exporter otlp_proto_http python c10.py
even though just simple python, it should give some logs in collector ,right ?

No it doesn't if you don't have any instrumentation
It is there 4317/TCP,4318/TCP,55680/TCP,55681/TCP,14250/TCP,14268/TCP,9411/TCP,8888/TCP

As I mentioned earlier you don't get anything if there is no instrumentation. Your c10.py has nothing that produces telemetry

and what scenario for 55681/TCP,14250/TCP,14268/TCP,9411/TCP,8888/TCP,8889/TCP

4317 is for gRPC and 4318 is for HTTP. Some language/runtime version may not go well with gRPC and might cause problems. You may want to take a look at the OTEL collector for all the details.

I only found some link for troubleshooting https://signoz.io/docs/install/troubleshooting/#signoz-otel-collector-address-grid but it just mentioned out 4317
