Performance Counter check to monitor APP_POOL_WAS returning error

[rarafan]

Attempting to setup check to monitor the Performance Counter for APP_POOL_WAS under Microsoft IIS.
It works when running in the windows power shell but not when running the check.

Base on this we can see this is a counter that can be monitored - https://techcommunity.microsoft.com/t5/iis-support-blog/performance-counters-for-monitoring-iis/ba-p/683389

These are the results when we run in in the command line -

PS C:\Users\administrator> Get-Counter '\APP_POOL_WAS(DefaultAppPool)\Current Application Pool State'

If we run it under NCPA this is what we see -
