Displaying Swapping Statistics (vmstat –S)

Run vmstat -S to show swapping statistics.

$ vmstat -S
kthr      memory            page            disk          faults      cpu
 r b w   swap  free  si  so pi po fr de sr dd f0 s1 --   in   sy   cs us sy id
 0 0 0 862608 364792  0   0  1  0  0  0  0  0  0  0  0  406  394  213  1  0 99

The swapping statistics fields are described in the following list. For a description of the other fields, see Table 3–2.


Average number of LWPs that are swapped in per second


Number of whole processes that are swapped out

Note -  The vmstat command truncates the output of si and so fields. Use the sar command to display a more accurate accounting of swap statistics.
