Starting with Oracle Solaris 11, you can use the fsstat command to report file system operations. You can report file system operations in multiple ways. For example, reports based on mount point or file system type.
For example, use the fsstat command to display all ZFS file system operations since the ZFS module is loaded:
$ fsstat zfs new name name attr attr lookup rddir read read write write file remov chng get set ops ops ops bytes ops bytes 268K 145K 93.6K 28.0M 71.1K 186M 2.74M 12.9M 56.2G 1.61M 9.46G zfs
For example, use the fsstat command to display all file system operations since the /export/ws file system is mounted:
$ fsstat /export/ws 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 18.1K 0 12.6M 52 0 0 0 0 /export/ws
The default form is to report statistical information in easy to understand values, such as GB, KB, and MB. For more information, see the fsstat(1M) man page.
