File System Monitoring Tool (fsstat)

A new file system monitoring tool, fsstat, is available to report file system operations. Activity can be reported by mount point or by file system type.

The following fsstat example shows how to display all ZFS file system operations.


$ fsstat zfs
 new  name   name  attr  attr lookup rddir  read read  write write
 file remov  chng   get   set    ops   ops   ops bytes   ops bytes
8.26K  240K 6.34K 4.03M 6.33K  12.6M  482K  204K 1.24G 13.4K  363M zfs

The following fsstat example shows how to display file system operations for the /export/home mount point.


$ fsstat /export/home
 new  name   name  attr  attr lookup rddir  read read  write write
 file remov  chng   get   set    ops   ops   ops bytes   ops bytes
    0     0     0   972     0    224    22     0     0     0     0 /export/home

The following fsstat example illustrates how to display file system operations for all file system types.


$ fsstat -F
 new  name   name  attr  attr lookup rddir  read read  write write
 file remov  chng   get   set    ops   ops   ops bytes   ops bytes
