Table 39 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
code, kernel management, and ISSU functions. 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
Caches
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:Buffers + Mem:Cached, which indicates
the physical memory available for applications.
Swap Swap memory.
