Distributed Tracing in .NET Applications using OpenTelemetry

Distributed tracing in a .NET application can significantly enhance visibility into request flow and performance bottlenecks, as demonstrated by implementing OpenTelemetry in a simple order processing service. OpenTelemetry serves as a vendor-neutral framework that standardizes the collection and export of telemetry data, making it compatible with various backends such as OpenObserve. The tutorial provides a step-by-step guide to setting up distributed tracing using auto-instrumentation and manual instrumentation to capture traces in a .NET Web API, specifically through the creation and retrieval of orders. The process involves configuring OpenTelemetry packages, creating spans using the Activity class, and exporting traces to OpenObserve for visualization. By integrating these practices, developers can gain insights into both framework-level and application-specific operations, ultimately improving debugging and performance monitoring.
