dotnet-observability

Modern observability for .NET applications using OpenTelemetry, structured logging, health checks, and custom metrics. Covers the three pillars of observability (traces, metrics, logs), integration with Microsoft.Extensions.Diagnostics and System.Diagnostics, and production-ready health check patterns.

Scope

• OpenTelemetry traces, metrics, and logs setup
• Health check endpoints and liveness/readiness patterns
• Custom metrics with System.Diagnostics.Metrics
• Structured logging integration with OTel export

Out of scope

• DI container mechanics and service lifetimes -- see [skill:dotnet-csharp-dependency-injection]
• Async/await patterns -- see [skill:dotnet-csharp-async-patterns]
• Testing observability output -- see [skill:dotnet-integration-testing]
• Middleware pipeline patterns (request logging, exception handling) -- see [skill:dotnet-middleware-patterns]
