They are saying sometime it will not be mapped to apppool, so lets have apppool as filter but get all metrics from http request queue and one with flterable apppool others as it is.
To do this what can i make change in my PR?

If you have any Windows system - you can enable IIS and test it out.

At the moment, i have just an Mac. And I would not like to install the IIS on the gaming box. Since the Mac is an ARM CPU, I can't run Windows inside a VM.
