Learn ASP.NET Core health checks step by step — monitor databases, APIs, and memory in production with real C# examples. Start monitoring like a pro today. When your production app goes down at 2 AM, how quickly will you know? If your answer is "when a customer emails us," you need ASP.NET Core health checks . Health checks are lightweight endpoints built into ASP.NET Core that report whether your application — and everything it depends on, like SQL Server, Redis, or third-party APIs — is actually working. Load balancers, Kubernetes, and monitoring dashboards poll these endpoints continuously, so failures are detected and handled in seconds, not hours. In this guide, you'll learn how to add a health check endpoint in ASP.NET Core, monitor databases and external services, distinguish liveness from readiness probes, secure your endpoints, and visualize everything with a dashboard. Every example is runnable on .NET 8 and .NET 9. What Are Health Checks in ASP.NET Core? ...

If your production API goes down at 3 a.m., how do you find out first — from your monitoring system, or from an angry customer? Health checks in ASP.NET Core are the built-in feature that lets your monitoring tools, load balancers, and orchestrators know whether your app is alive, ready to serve traffic, and able to reach its dependencies. In this tutorial you'll learn how to add health checks in ASP.NET Core from scratch, wire up readiness and liveness probes for Kubernetes, check databases and external services, and follow the best practices seniors use in real production systems. Whether you're a beginner searching for "how to add a health check endpoint" or a senior engineer looking for advanced health check patterns in C#, this guide covers it all with runnable code for .NET 8 and .NET 9.
