请问free列的数值的单位是什么?1byte?kB?谢谢
我执行man vmstat后得到的其中一段
vmstat(1) vmstat(1)
-s Print the total number of several kinds of paging-
related events from the kernel sum structure that have
occurred since boot-up or since vmstat was last
executed with the -z option.
-z Clear all accumulators in the kernel sum structure.
This option is restricted to the super user.
If none of these options is given, vmstat displays a one-line summary
of the virtual memory activity since boot-up or since the -z option
was last executed.
Column Descriptions
The column headings and the meaning of each column are:
procs Information about numbers of processes in various
states.
r In run queue
b Blocked for resources (I/O, paging, etc.)
w Runnable or short sleeper (< 20 secs) but
swapped
memory Information about the usage of virtual and real
memory. Virtual pages are considered active if they
belong to processes that are running or have run in
the last 20 seconds.
avm Active virtual pages
free Size of the free list
是不是还要查freelist的单位?谢谢!
