How to instrument ServiceStack .NET Core Application

[Samrat Alamgir]

Hi,

I want to add Prometheus to a ServiceStack .NET core (3.1) application. But seems the regular way to add the middleware is not working.

like, app.UseMetricServer(); is not working.

Then I found a work around, that creating a MerticServer in Configure() method like this:

var metricServer = new MetricServer(1234);
 metricServer.Start();

But this requires run the Visual Studio as Admin mode.

Now I am getting the ServerMetrics for the new endpoint, but can't get HttpMetrics after adding the app.UseHttpMetrics();

So what's the actual way to configure and get default HttpMetrics for endpoints in ServiceStack. 

Thanks,
