Learners will gain hands-on experience installing and configuring the OpenTelemetry SDK in .NET applications. They will instrument an ASP.NET Core API to capture metrics, logs, and distributed traces, then export this telemetry to backends like Jaeger, Prometheus, and Azure Monitor. By the end of the course, learners will understand how to apply unified observability practices to monitor, debug, and optimize modern microservices and cloud-native systems. In this module, learners move from theory to practice by installing and configuring the OpenTelemetry SDK in a .NET API and exporting telemetry to Jaeger, Prometheus, and Azure Monitor. A coach dialogue guides them through diagnosing bottlenecks using traces and metrics, while step-by-step videos demonstrate SDK setup, configuration, and visualization with Docker-based backends. A written guide provides a lasting reference, and a hands-on lab challenges learners to instrument and trace API calls, reinforcing how unified observability enables real-world debugging and optimization.

Learners will explore how unified observability through OpenTelemetry enables faster root cause analysis and proactive performance monitoring. They will see how combining metrics, logs, and traces provides a complete view of .NET applications in action. By applying these practices, learners will be able to diagnose issues more effectively and ensure their systems remain reliable and performant. In this final section, learners apply everything they’ve learned to diagnose real microservice issues and build confidence as observability practitioners. A coach dialogue introduces a root cause mystery, followed by demonstrations of analyzing traces in Jaeger and monitoring metrics in Prometheus, showing how these tools complement each other. A reading on reliability engineering connects observability to resilience practices, while a hands-on lab challenges learners to troubleshoot a microservice outage. The course concludes with a capstone project to build a full observability stack using OpenTelemetry, a graded knowledge check, and career resources to help learners explore observability engineering roles. An outro video and promotional piece reinforce next steps and the broader industry relevance of OpenTelemetry.
