Plugin execution fails because arguments could not be validated and properly set. An example error could be
The "*" was not recognized as the name of a program, cmdlet, function, script file, or executable. Check the spelling of the name and that the path is correct (if included), and repeat the process.
This error can happen if array arguments either contain special characters, like
* or spaces. By using the configuration provided by Icinga for Windows, array arguments are taken from your configuration and re-rendered using Icinga DSL as PowerShell arrays.

Once the Performance Counter is put between single quotes
