Monitoring Zone File System Activity

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.
