App Metrics .netCore 3.0 does not tracking endpoint

Question

When I using App Metric to report into influxDb for an web API with .netcore 2.1, it return the calling enpoint info like the image

But when I upgrade it to .netcore 2.2 or 3.1 then it return nothing

Is it wrong in config some thing when i upgrade? Looking for your help!

Answer 1

I found out that it worked after adding .AddMetrics() right behind .AddMvc() in Startup.cs

using Microsoft.AspNetCore.Mvc;
....
public void ConfigureServices(IServiceCollection services) {
....
services.AddMvc().AddMetrics()....
}
