.NET Observability Explained
Observability for .NET means understanding application behavior from external outputs—logs, traces, metrics, and request context—so teams can diagnose failures and latency in production without redeploying with extra debug code.
What is .NET observability?
Observability is the ability to infer internal system state from telemetry. For .NET services, that includes HTTP requests, database calls, exceptions, correlation IDs, and method-level timing. ArgusLogs focuses on deep automatic capture at compile time rather than asking developers to instrument every code path manually.
Why it matters
Microservices, EF Core, background workers, and third-party HTTP calls make production failures hard to reproduce. Observability reduces mean time to recovery by preserving structured context around each request and SQL statement.
How ArgusLogs helps
ArgusLogs uses compile-time IL weaving (via ArgusLogs.DataAnnotation and the argus-weaver MSBuild tool) to inject instrumentation into your assemblies. Mark methods with [LogMethod] or enable broader weaving rules, then consume logs through files, TieredStorage, or the embedded ArgusLogs.UI viewer.
Frequently asked questions
Does ArgusLogs replace OpenTelemetry?
ArgusLogs complements logging and tracing workflows. It automatically captures rich method and data-access context. Teams may still export to OTLP-compatible sinks where configured.
