@User Have you added environment variables before running this command OTEL_METRICS_EXPORTER=none OTEL_RESOURCE_ATTRIBUTES=service.name=<service_name> OTEL_EXPORTER_OTLP_ENDPOINT="http://<IP of SigNoz Backend>:4317" opentelemetry-instrument <your run command>

The instructions on how to run this sample app might also be helpful - https://github.com/SigNoz/sample-flask-app

Also which OS are you trying this on - Linux or Mac?

BTW I was using https://signoz.io/blog/python-application-monitoring/ This page to help me setup, and I used

OTEL_RESOURCE_ATTRIBUTES=service.name=entri-main-service OTEL_EXPORTER_OTLP_ENDPOINT="<http://localhost:4317>" opentelemetry-instrument ./manage.py runserver --noreload

this to run the server for my project

@User Please follow the above doc.

Maybe you need to set

export DJANGO_SETTINGS_MODULE=mysite.settings

as given in https://stackoverflow.com/a/26089302/3243212

I did try an initial googling and did that answer suggested in the above post. Its supposed to be run just before the init for django OT calls the settings Lazy object to insert middlewares. Right?
