In this tutorial, we will use OpenTelemetry Go libraries to instrument a Go application and then visualize it using an open-source observability tool - SigNoz.
Steps to follow:
- Installing SigNoz
- Instrumenting a Go application with OpenTelemetry
- Adding custom attributes and custom events to spans
- Monitor with SigNoz dashboards
