A new file system monitoring tool, fsstat, is available to report file system operations from Oracle Solaris 11 release. You can use several options to report activity, such as by mount point or by file system type.
For example, the following fsstat command displays all ZFS file system operations since the ZFS module was 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, the following fsstat command displays all file system operations since the /export/ws file system 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.
