Distributed Tracing in .NET Core and Azure
Short summary
Distributed tracing tracks requests as they traverse microservices to pinpoint failures, measure latency, and visualize service dependencies. .NET provides native support through the Activity API, automatically propagating trace context via W3C Trace Context headers between services. OpenTelemetry offers vendor-neutral instrumentation, while Azure Application Insights serves as the backend for production monitoring, visualization, and performance analysis.
- •Activity API provides native .NET distributed tracing with automatic context propagation
- •OpenTelemetry enables vendor-neutral instrumentation across multiple backend exporters
- •W3C Trace Context standard ensures consistent trace ID propagation between services
