Health Checks Building Block

Building Block for using the ASP.Net Health Checks

Registration

You can use the AppAddHealthChecks extension method on IServiceCollection to add a HealthChecksService to th IoC container. This returns a HealthChecksBuilder, which can be used to configure the health checks :

 public void ConfigureServices(IServiceCollection services)
 {
 ...
 services.AppAddHealthChecks(configuration)
 .AddDbContextCheck<YessaBaseContext>()
 .AddDiskStorageHealthCheck
 // etc
 }

Next, you also need to call the AppMapHealthCheck method to register the health checks endpoint, providing an instance of the configuration object.

 app.UseEndpoints(endpoints =>
 {
 endpoints.MapDefaultControllerRoute();
 endpoints.AppMapHealthCheck(_configuration);
 });

Configuration

Example:

 "App": {
 
 "HealthChecks": {
 "MaximumAllowedMemoryInMB": "200",
 "TokenAuthorizationEnabled": true,
 "RequiredToken": "__healthChecksToken__"
 }
 },

• The token (if enabled) needs to be a random string, like a GUID. This then needs to be sent as a query parameter with any request, to be authorized: healthcheckurl?token=[token]. This can be used to setup Application Insights availability monitoring.
