Observability in .NET: Application, Service, and Component Telemetry

Modern software architectures demand clear visibility into how code behaves in production. Understanding how to collect, organize, and analyze telemetry data at different levels of your application is essential for maintaining healthy and reliable systems. This text-based course guides you through the core concepts of software observability, helping you distinguish between and implement application-level, service-level, and component-level telemetry. You will learn how to instrument your .NET applications to gather meaningful logs, metrics, and traces, ensuring you can diagnose issues quickly and understand system performance deeply. What you'll learn: - Understand foundational observability concepts, including logs, metrics, and distributed tracing. - Differentiate between telemetry collected at the application, service, and component levels. - Configure OpenTelemetry to capture standardized diagnostic data across your ecosystem. - Implement Application Insights to monitor performance and track dependencies. - Design structured logging strategies that make production issues easier to debug. - Practice instrumenting .NET code to emit custom metrics and trace contexts. You will start with key definitions and foundational concepts of observability before moving on to practical architectural patterns. The material guides you step-by-step from high-level application monitoring down to fine-grained component-level diagnostics. This course is designed for beginner to intermediate .NET developers and system architects who want to build a solid foundation in modern system observability. No prior experience with telemetry tools is required. Start reading today to build more observable, reliable, and maintainable .NET applications.
