Learn how to set up a complete observability stack for your .NET applications using Grafana Cloud and OpenTelemetry. This tutorial shows you how to integrate metrics, traces, and logs into your existing projects with minimal configuration.

Grafana Cloud offers a generous free tier with 10,000 metrics, 50GB of logs, and 50GB of traces per month - perfect for most applications. I'll walk you through configuring OpenTelemetry in a real .NET microservices application, setting up the necessary NuGet packages, and connecting everything to Grafana Cloud.

The demo covers how distributed tracing captures requests flowing across service boundaries. You'll see how to monitor database queries, HTTP requests, and message queue operations all in one unified dashboard.

By the end of this tutorial, you'll have a production-ready observability solution that helps you debug issues faster and understand your application's performance without expensive APM tools.
