Reporting Per-Zone File System Statistics

The following examples show how to report file system activity for non-global zones. For more examples, see the fsstat(8) man page.

Example 5-8 Monitoring Activity in Specific Zones

This command reports on file system activity for specified zones. The separate ‐z options specify each zone to monitor.

global$ pfexec fsstat -z ZoneA -z ZoneB zfs tmpfs
 new  name   name  attr  attr lookup rddir  read read  write write
 file remov  chng   get   set    ops   ops   ops bytes   ops bytes
   93    82     6  163K   110   507K   148 69.7K 67.9M 4.62K 13.7M zfs:ZoneA
  248   237   158  188K   101   612K   283 70.6K 68.6M 4.71K 15.2M zfs:ZoneB
12.0K 1.90K 10.1K 35.4K    12  60.3K     4 25.7K 29.8M 36.6K 31.0M tmpfs:ZoneA
12.0K 1.90K 10.1K 35.6K    14  60.2K     2 28.4K 32.1M 36.5K 30.9M tmpfs:ZoneB

Tip:

To report on all zones, including the global zone, use the ‐Z option (uppercase) instead of the -z zonename option.

Example 5-9 Displaying Per-Zone fstype Statistics for All Zones

This example shows how to report aggregated file system activity for all zones, including the global zone. The administrator requests reports on the file system types tmpfs and zfs for each zone running on the system.

global$ pfexec fsstat -A -Z zfs tmpfs
 new  name   name  attr  attr lookup rddir  read read  write write
 file remov  chng   get   set    ops   ops   ops bytes   ops bytes
