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 1.71K 1.16K 37 371K 562 1.90M 1.04K 151K 142M 21.9K 55.3M ufs 0 0 0 1.60K 0 2.93K 344 1.30K 761K 0 0 proc 0 0 0 0 0 0 0 0 0 0 0 nfs 8.31K 240K 6.37K 4.04M 6.48K 12.6M 482K 204K 1.25G 13.7K 365M zfs 29 12 12 37.4K 8 22.5K 28 1.04K 2.34M 120 76.1K lofs 10.8K 4.72K 5.43K 54.6K 49 19.8K 28 173K 610M 513K 487M tmpfs 0 0 0 338 0 0 0 44 12.2K 0 0 mntfs 1 1 1 429 1 14.3K 115 1.34K 1002K 0 0 nfs3 12 6 9 150 0 442 30 91 3.32M 12 69.2K nfs4 1 0 1 20.8K 0 20.5K 0 0 0 0 0 autofs |
