Automating Data Collection for Memory, CPU, and Disk issues using CLUE

How does the config.xml file determine the threshold for the highcpuwmi task?  I see the threshold value of 320, but what does that correlate to?  If I wanted the the logging to start at say 40% CPU what should this value be?  Or is there another place that actually sets the threshold?

Also, I'm getting the following in the highcpuwmi.log file:

"Get-Counter : The data in one of the performance counter samples is not valid. 
View the Status property for each PerformanceCounterSample object to make sure 
it contains valid data.
At C:\Program Files\Clue\Test-CounterRule.ps1:53 char:23
+ ... terData = @(Get-Counter -Counter $CounterPath -SampleInterval $Sample ...
+                 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : InvalidResult: (:) [Get-Counter], Exception
    + FullyQualifiedErrorId : CounterApiError,Microsoft.PowerShell.Commands.Ge 
   tCounterCommand"

I'm running Powershell version 5.1.14393.7513.

Was this code written for a previous version and what would need to change to work with the new version?

Thanks.
