This is my HealthCheck configure public static class HealthChecksBuilderExtensions { public static void AddDruidAIHealthChecks(this IServiceCollection services) { // Add your health checks here var healthChecksBuilder = services.AddHealthChecks(); healthChecksBuilder.AddCheck

    services.ConfigureHealthCheckEndpoint("/health-status");
    
    // If you don't want to add HealthChecksUI, remove following configurations.
    var healthChecksUiBuilder = services.AddHealthChecksUI(settings =>
    {
        settings.AddHealthCheckEndpoint("DruidAI Health Status", $"http://{Dns.GetHostName()}/health-status");
    });
    
    // Set your HealthCheck UI Storage here
    healthChecksUiBuilder.AddInMemoryStorage();
    
    services.MapHealthChecksUiEndpoints(options =>
    {
        options.UIPath = "/health-ui";
        options.ApiPath = "/health-api";
    });
}

private static IServiceCollection ConfigureHealthCheckEndpoint(this IServiceCollection services, string path)
{
    services.Configure<AbpEndpointRouterOptions>(options =>
    {
        options.EndpointConfigureActions.Add(endpointContext =>
        {
            endpointContext.Endpoints.MapHealthChecks(
                new PathString(path.EnsureStartsWith('/')),
                new HealthCheckOptions
                {
                    Predicate = _ => true,
                    ResponseWriter = UIResponseWriter.WriteHealthCheckUIResponse,
                    AllowCachingResponses = false,
                });
        });
    });

    return services;
}

private static IServiceCollection MapHealthChecksUiEndpoints(this IServiceCollection services, Action<global::HealthChecks.UI.Configuration.Options> setupOption = null)
{
    services.Configure<AbpEndpointRouterOptions>(routerOptions =>
    {
        routerOptions.EndpointConfigureActions.Add(endpointContext =>
        {
            endpointContext.Endpoints.MapHealthChecksUI(setupOption);
        });
    });

    return services;
}

}

It seems error on Dns.GetHostName() as I return "a7fe589a2946", right? can i get host name from Configuration app setting?
