How to get the current CPU/RAM/Disk usage in a C# web application using .NET CORE?

Question

I am currently looking for a way to get the current CPU/RAM/Disk usage in a C# web application using .NET CORE.

For CPU and ram usage, I use PerformanceCounter Class

Processor information is available via System.Diagnostics:

var proc = Process.GetCurrentProcess();
var mem = proc.WorkingSet64;
var cpu = proc.TotalProcessorTime;
Console.WriteLine("My process used working set {0:n3} K of working set and CPU {1:n} msec", 
    mem / 1024.0, cpu.TotalMilliseconds);

DriveInfo is available for Core by adding the System.IO.FileSystem.DriveInfo package
