Utility: Self-made Resource Monitor

[Jamesthe1]

I’m working on a C++ program that will monitor select windows and log the following usages n times a second:
- Memory (in Kb)
- GPU (%)
- CPU (%)
- Disk Reads
- Disk Writes

so I know what to upgrade while I’m playing a game in fullscreen. The question is:
Is there a library for these? If not, what can I do for what I want?

Obviously you were mistaken...
