Description
Physical memory shared by processes.
Physical memory used for buffers.
Physical memory used for caches.
Free memory ratio.
-/+ buffers/cache:used = Mem:Used – Mem:Buffers – Mem:Cached, which indicates
the physical memory used by applications.
-/+ buffers/cache:free = Mem:Free + Mem:Buffers + Mem:Cached, which indicates
the physical memory available for applications.
Swap memory.
