zvmstat - print vmstat style info per Zone. Uses DTrace. zvmstat [-t] [interval [count]] This program must be run from the global zone as root. Since this uses DTrace, only the root user or users with the dtrace_kernel privilege can run this command. Solaris stable - needs the syscall and vminfo providers.

-t Print timestamps, string

interval Duration for each sample, seconds. default is 1.

count Number of samples. default is 1.

Print virtual memory statistics every second, # zvmstat

Print every 5 seconds, 6 times, # zvmstat 5 6

ZONE zonename

re page reclaims, pages

mf minor faults, pages

fr pages freed, pages

sr scan rate, pages

epi executable page ins, pages

epo executable page outs, pages

epf executable frees, pages

api anonymous page ins, pages

apo anonymous page outs, pages

apf anonymous frees, pages

fpi filesystem page ins, pages

fpo filesystem page outs, pages

fpf filesystem frees, pages

Most of the statistics are in units of pages, unlike the original vmstat command which sometimes uses kilobytes. All page values are a total for the sample duration. As this program does not use Kstat, there is no summary since boot line.

See the DTraceToolkit for further documentation under the Docs directory. The DTraceToolkit docs may include full worked examples with verbose descriptions explaining the output. zvmstat will run until Ctrl-C is hit, or until the count argument has been satisfied.
