Monitoring your NestJS application is critical for performance management. But setting up monitoring for NestJS applications can get cumbersome requiring multiple libraries and patterns. That's where OpenTelemetry comes in.

In this tutorial, we will use SigNoz as a backend. SigNoz is an open-source APM tool that can be used for both metrics and distributed tracing.

Let's get started and see how to use OpenTelemetry for a NestJS application.
