The fsstat utility can be used to report file operations statistics for non-global zones.
The global zone can see the kstats of all zones on the system. Non-global zones only see the kstats associated with the zone in which the utility is run. A non-global zone cannot monitor file system activity in other zones.
The –z option is used to report on file system activity per zone. Multiple –z options can be used to monitor activity in selected zones. The option has no effect if only used to monitor mountpoints and not fstypes.
The –Z option is used to report file system activity in all zones on the system. This option has no effect if used with –z option. The option has no effect if only used to monitor mountpoints and not fstypes.
The –A option is used to report on aggregate file system activity for the specified fstypes across all zones. This is the default behavior if neither –z or the –Z option is used. The –A option has no effect if only used to monitor mountpoints and not fstypes.
When used with either the –z or the –Z option, the –A option displays the aggregate for the specified fstypes across all zones on a separate line. The option has no effect if only used to monitor mountpoints and not fstypes.
See the fsstat(1M) man page for more information.
