zfs-stats

ZFS statistics tool for Linux.

The zfs-stats script displays general ZFS information
and human-readable ZFS statistics of the following subsystems:

• ARC
• L2ARC
• DMU (zfetch)
• vdev cache

The script is a fork of Martin Matuška’ zfs-stats for FreeBSD which
in turn is a port of Jason J. Hellenthals’ arc_summary.pl

Use the customised linux-kstat Perl module.

Memory information has not fully been updated and sysctl ZFS tunables have been disabled. Tested on Ubuntu 12.04 LTS
