prometheus-net is a .NET library for instrumenting application code with Prometheus metrics such as counters, gauges, histograms, and summaries. It includes built-in integrations for ASP.NET Core request metrics, gRPC, IHttpClientFactory, health checks, and Pushgateway publishing.

Use cases

• instrument a .NET application with Prometheus metrics
• expose a /metrics endpoint from ASP.NET Core
• track HTTP request duration and counts in ASP.NET Core
• collect gRPC request metrics in .NET
• push metrics to Prometheus Pushgateway
• count exceptions and track in-progress operations
• monitor HttpClient calls via IHttpClientFactory

When to choose

• you run .NET or .NET Framework services monitored by Prometheus
• you need custom application metrics with labels and histograms
• you want built-in ASP.NET Core and gRPC metric middleware

When to avoid

• your application is not on the .NET platform
• you need a full metrics storage and query engine rather than instrumentation (use the Prometheus server)
• you target runtimes older than .NET Framework 4.6.2 or .NET 6.0
