Windows server 2012 & 2016

For my Server 2016 I had to manually go to “Administrative Tools” > Performance Monitor > Data Collector Sets > User Defined > Server Manager Performance > Performance Counters…If you select “Add” under “Network Interface” you can see the exact names of the interfaces you can monitor. On my 2016 server this name was slightly different from the description name on the adapter. Once I mirrored the name from here, all worked!

I also added the “-c” & “-w” options to the .sh for setting the critical and warrning levels, works great!
