    Description copied from interface: MemoryStats
    
    Returns total physical memory available in OS.

  - getFreePhysical
```
public long getFreePhysical()
```
    Description copied from interface: MemoryStats
    
    Returns free physical memory available in OS.
    Some operating systems have cached memory regions in which they store hot cached resources like files. Cached memory is used for allocations when required. So although this cached region is assumed as free, operating systems generally report this region as used not free.
