Getting some statistics

[Wicked_Caty]

I've written a small surveillance tool for one of my programs. It shows the time that has already passed, the estimated time until the end, the average time of the steps, and the progress in %.

It works pretty well, but I want to add some stats. That'd be the usages of the CPU, RAM, network and hard-drive of all threads in %. Basically what you see in the taskmanager, but without the list of every single process.

I'm aware that there's no in-built function for that, and that I'd need an additional library. Are there any for that? Simply functions that return the stats mentioned above. Thanks!

Edit:   I run an ASUS R752M with an Intel BayTrail M3540 on Windows 10 64-bits.
