Hi there, I have a fastapi application which is running in docker-compose with nginx proxy and I also used opentelemetry for metrics collections and passing the metrics to signoz collection at port 4317. I don't know why its not showing the application in signoz. If anyone can help me in this, would be really appreciable.

Are you sure your instrumentation is working peoperly? Use `ConsoleExporter` to config if any telemetry is getting written to stdout.

I also have a NestJs application and facing the same issue. I tried following the instrumentation docs but the application wont show under services.

I have followed this documentation.

The dummy application which is mentioned in this article is working but my real application which is running on docker inside nginx is not showing in the signoz dashboard.
