HI,

please run Get-Counter -Counter "\HTTP Service Request Queues(*)\CurrentQueueSize", I would like to see some examples.

Secondly, I'm not sure, if the site label is correct. Are the counter reports sites or app pool?

lastly, Please extend the documentations. https://github.com/prometheus-community/windows_exporter/blob/master/docs/collector.iis.md

And take care of CI please.

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?
