Uses DTrace. +.SH SYNOPSIS +.B vmstat.d +.SH DESCRIPTION +This has been written to demonstrate fetching the same data as vmstat +from DTrace. This program is intended as a starting point for other +DTrace scripts, by beginning with familiar statistics. + +Since this uses DTrace, only the root user or users with the +dtrace_kernel privilege can run this command. +.SH OS +Solaris +.SH STABILITY +unstable - uses various kernel symbols. +.SH EXAMPLES +.TP +Print virtual memory statistics every second, +# +.B vmstat.d +.PP +.SH FIELDS +.TP +w +swapped out light weight processes +.TP +swap +virtual memory free, Kbytes +.TP +free +free RAM, Kbytes +.TP +re +page reclaims, Kbytes +.TP +mf +minor faults, Kbytes +.TP +pi +page ins, Kbytes +.TP +po +page outs, Kbytes +.TP +fr +pages freed, Kbytes +.TP +sr +scan rate, pages +.TP +in +interrupts, number +.TP +sy +system calls, number +.TP +cs +context switches, number +.PP +.SH NOTES +Most of the statistics are in units of kilobytes, unlike the +original vmstat command which sometimes uses page counts. + +As this program does not use Kstat, there is no summary since boot line. + +Free RAM is both free free + cache free. +.PP +.SH DOCUMENTATION +See the DTraceToolkit for further documentation under the +Docs directory.
