The deployment scenarios of modern applications and services are mainly reflected in clustering, microservices and containerization, all of which are based on health checks for deployed applications or services. The health check provided by ASP.NET not only may determine the availability of the target application or service, but also has the function of issuing health reports. The health check function of the ASP.NET framework is completed through the HealthCheckMiddleware middleware. We can not only use this middleware to determine the availability of the current application, but also register the corresponding IHealthCheck object to complete health checks for different aspects.
