Health Check UI not working

[justinteaw]

when I go to hc-ui I see "Could not retrieve health checks data"

This is what i have in my startup page: public void ConfigureServices(IServiceCollection services) { services .AddHealthChecksUI() .AddHealthChecks() .AddSqlServer(connectionString: Configuration["Data:ConnectionStrings:Monitoring"]);

    }

public void Configure(IApplicationBuilder app, IHostingEnvironment env) {

        app.UseHealthChecks("/hc", new HealthCheckOptions()
        {
            Predicate = _ => true,
            ResponseWriter = UIResponseWriter.WriteHealthCheckUIResponse
        })
        .UseHealthChecksUI(setup => 
        {
            setup.ApiPath = "/hc";
            setup.UIPath = "/hc-ui";
        });

    }

Are you configuring the appsettings like the UI sample project? You have to tell the UI the endpoints to monitorize. In this case the same host that registers the hcs

[justinteaw]

it's similar. What i have currently is:

Snippet

"HealthChecks-UI": { "HealthChecks": [ { "Name": "HTTP Basic", "Uri": "http://localhost:5001/hc" } ], "Webhooks": [], "EvaluationTimeOnSeconds": 10, "MinimumSecondsBetweenFailureNotifications": 60 }

Hi @justinteaw

You have invalid configuration, please review the samples in order to set this correctly, in your code you have the same path for ui and healthcheks results.

app.UseHealthChecks("/hc", new HealthCheckOptions()
        {
            Predicate = _ => true,
            ResponseWriter = UIResponseWriter.WriteHealthCheckUIResponse
        })
        .UseHealthChecksUI(setup => 
        {
            setup.ApiPath = "/hc";
            setup.UIPath = "/hc-ui";
        });

You can set, for example UseHealthChecks("/healthz"...)

and USeHealthChecksUI() without setup. After this in configuration set http://localhost:[port]/healthz

You have a sample for this scenario on https://github.com/Xabaril/AspNetCore.Diagnostics.HealthChecks/tree/master/samples/HealthChecks.UIAndApiCustomization

Great, that was it! thanks!

Hello @ranouf, you are exposing healthcheck results and api in the same /hc path.

Change the API path or use the default

Also in the appsettings, the target path is the one you register with UseHealthChecks (in this case /hc) instead of hc-ui that is the spa path to see the html site.

I recommend you to check and run the samples.

The things is the sample are with .net core 3.0 and I m using 2.2. I tried to go back in the history, but I didn t succeed to find to good way to configure it :)

Thanks @CarlosLanderas for answering, you were right, the issue came from the appsettings.
