Excel Charts from PowerShell data

Looking to make Reports more sharing friendly?

First start with an additional module known as “importExcel” (the link to the psgallery details is there)

Truth be told you can also Export to excel as well even though the name doesn’t give that away.

Script Time!!!! (I actually had to type this because I say this in real life in response to real challenges and tasks.

Here is a script that takes the performance counters from a machine, note this is different depending on the OS and the hardware. you can explore performance counters inside of the performance monitor tool searchable inside the start menu.

<#Script to gather Performance Data From PCs
