ApplicationInsights, Net core and HostBuilder (not Asp.net)

Question

Can someone explain to me how to get advanced ApplicationInsights modules like PerformanceCollector working on a simple IHostService/HostBuilder .Net core application?

With a setup like this, I managed to get ILogger logs into ApplicationInsights:

var builder = new HostBuilder()
    .ConfigureServices((hostContext, services) =>
    {
        services.AddLogging();

        // ApplicationInsights initializer
        services.Configure(config => config.InstrumentationKey = "52xxxx8a-2xx2-4xx8-bxx6-4xxxxxxxxxxxx2");
        services.Configure(config => config.SamplingPercentage = 10.0);
        services.AddSingleton();
        services.AddSingleton();
        services.AddSingleton();
        services.AddSingleton();
        services.AddSingleton();
        services.AddSingleton();
    })
    .ConfigureLogging(configureLogging =>
    {
        configureLogging.AddConsole();
        configureLogging.AddDebug();
        configureLogging.AddApplicationInsights();
    });

builder.Build().Run();

But for example PerformanceCollectorModule is doing nothing. No performance metrics are sended.

I try to look how Asp.Net Core Extention is working, but I don't understand it.

There is a new package from Application Insights to use in non Asp.Net application as your example. Remove all the ApplicationInsights packages you have, and just add the following one:

Then call services.AddApplicationInsightsTelemetryWorkerService(); in your ConfigureServices. (remove all other application insights related code)

And modify appsettings.json with instrumentation key as below:.

    {
      "ApplicationInsights": {
        "InstrumentationKey": "putinstrumentationkeyhere"
      },
      "Logging": {
        "LogLevel": {
          "Default": "Warning"
        }
      }
    }

(I work in the application insights team, and this new feature is being documented officially. There will be a sample app as well once this is merged: https://github.com/Microsoft/ApplicationInsights-home/pulls)
