That's a really interesting thought, Ned. I'll have to check into gathering the data that we're looking at here using PC directly, and what the performance implications are. I believe that many of the WMI classes that I use are actually the same sources that PC actually uses ("Win32_PerfFormattedData_Perf*"), but I'm not confident how much overhead WMI adds versus PC. I'll look into it.

This may actually be an issue with syntax that I ran into a little while ago after I'd upgraded from PowerShell 2 to 3 or 4. If I get some time this week I'll review the posted scripts and update them if it's the same problem. Thank you for your feedback!

After you copy the scripts to that folder, you need to add a new sensor of type "EXE/Script Advanced," which will have a drop-down called "EXE/Script" that should list the script files.
