I converted my vbs scripts running under cscript to powershell. This improved data loss, improved speed and reduced the load on the system significantly. Huge CPU reduction

How to run PowerShell

Target[AK26-S125-VAL1_cpu]: `C:\WINDOWS\system32\windowspowershell\v1.0\PowerShell.exe C:\mrtg-2.14.5\mrtg-2.14.5\bin\vbscripts\PercentUsedCPU.ps1 10.X.X.X'

The blankvalues are place holders of value 0 since MRTG likes two values returned
