Table 33 Command output
Field Description
Mem Memory
usage information.
Total
Total size of the physical memory space that can be allocated.
The memory space is virtually divided into two parts. Part 1 is solely used for kernel
codes, and kernel management. Part 2 can be allocated and used for such tasks as
running service modules and storing files. The size of part 2 equals the total size
minus the size of part 1.
Used
Used physical memory.
Free Free
physical
memory.
Shared
Physical memory shared by processes.
Buffers Physical
memory used for buffers.
Cached
Physical memory used for caches.
FreeRatio
Free memory ratio.
-/+ Buffers/Cache
-/+ Buffers/Cache:Used = Mem:Used – Mem:Buffers – Mem:Cached, which
indicates the physical memory used by applications.
-/+ Buffers/Cache:Free = Mem:Free + Mem:B Mem:Cached, which indicates
the physical memory available for applications.
Swap Swap
memory.
