Use the –A option to report 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.
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.
Use the –Z option to report file system activity in all zones on the system. This option has no effect if used with the –z option. The option has no effect if only used to monitor mountpoints and not fstypes.
