Best way Health Checks in .NET Core

Implementing health checks in an ASP.NET Core application allows you to monitor the health and status of your services, such as databases, caches, and external APIs. This is essential for ensuring the availability and reliability of your application, especially in production environments where automated tools can probe these endpoints and take action if services are down or underperforming.

What Are Health Checks in ASP.NET Core?

Health checks are a built-in feature in ASP.NET Core that allows you to expose health status endpoints. These endpoints can be queried by monitoring systems (e.g., Kubernetes, AWS, Azure) to check if the application is running as expected and whether its dependencies (like databases, message queues, and caches) are functioning.

Step-by-Step Guide to Implement Health Checks in ASP.NET Core

1. Install Required NuGet Package

If you want to check the status of services like a database, you’ll need the Microsoft.Extensions.Diagnostics.HealthChecks package.

dotnet add package Microsoft.Extensions.Diagnostics.HealthChecks

2. Add Health Checks in Program.cs or Startup.cs
