NodeJs OpenTelemetry - Implementing Distributed Tracing in a NodeJS Application using OpenTelemetry

In this tutorial, we will implement distributed tracing for a nodejs application based on microservices architecture. To implement distributed tracing, we will be using open-source solutions - SigNoz and OpenTelemetry, so you can easily follow the tutorial.

More about SigNoz:
-----------------------------------
SigNoz - Monitor your applications and troubleshoot problems in your deployed applications, an open-source alternative to DataDog, New Relic, etc. Backed by Y Combinator.

SigNoz helps developers monitor applications and troubleshoot problems in their deployed applications. SigNoz uses distributed tracing to gain visibility into your software stack.

If you need any clarification or find something missing, feel free to raise a GitHub issue with the label documentation or reach out to us at the community slack channel.

But here when you had shown about UserService. It only shows UserService data, spans should be linked right? That's the purpose of distributed tracing
