Possible to cleanly apply custom AuthorizeAttribute to PrometheusMetricsController?

[Waddlen]

I want to protect the /metrics endpoint with my own auth attribute.

public class MyAuthAttribute : AuthorizeAttribute
{
    public override void OnAuthorization(HttpActionContext actionContext)
    {
        ... // stuff here
    }
}

However, I'm not sure how to cleanly apply this to PrometheusMetricsController. The cleanest I could come up with was inheriting it & applying it to the child:

[MyAuth]
public class TestController : PrometheusMetricsController
{
}

Then replacing the WebApiConfig.cs line PrometheusConfig.UseMetricsServer(config, "metrics"); with config.Routes.MapHttpRoute("Prometheus", "metrics", new { controller = "Test" });

Do you have any better ideas?

Thank you.

Looks like a great solution to me. Great job!

If you are implementing oAuth or something similar, consider creating a PR so that others can use it too :)
