There is currently a metric group `JVM` already. This adds a metric group
`Process`. What is the difference between the two? Can the new metrics be added
to the `JVM` group instead? That would help to prevent fragmenting the metric
groups.
I would also suggest to move the code that accesses CPU utilization into
the `Hardware` class. That is where we put code that uses OS specific utilities
to access for example memory and CPU.
Please also use the `OperatingSystem` class to identify operating systems.
