1 The following is a demonstration of the vmstat-p.d script,
4 We run both vmstat-p.d and the original vmstat(1M) command at the same time

39 Above we can see the columns are corresponding well. "re" and "mf" in the
40 DTrace output appear four times as large as they should be, because in the
41 DTrace output we are printing Kbs not page counts (for consistancy).
43 The DTrace output lacks the "summary since boot" line, as it is not using
44 Kstat to fetch this data.
47 The vmstat-p.d script is not intended itself as a useful program, rather it
48 is intended as a starting point for other DTrace scripts; a starting point
49 of familiar statistics to provide the programmer with a "common ground"
