The following is a demonstration of the xvmstat program.
Here we run it with no arguments. It will default to 1 second samples, and
will run forever,
# xvmstat

Both "swap" and "free" are in units of megabytes, the rest are in units of
pages. "maj" is major faults - a useful addition to the output.
There is no summary since boot line, as this program in not using the
Kstat data.
The following runs xvmstat with a 5 second interval,
# xvmstat 5
w swap free re maj mf cow pro sr epi epo epf api apo apf fpi fpo fpf

The values from "re" to "fpf" are per second values.
