# Plugin to monitor a ZFS Filesystem
|
|
#
|
|
# Wildcard-plugin to monitor a zfs filesystems.
|
|
# To monitor a filesystem, link zfs_fs_<zpool>_<filesystem> to this file. E.g.
|
|
#
|
|
# ln -s /usr/share/munin/node/plugins-auto/zfs_fs_ /etc/munin/node.d/zfs_fs_tank_foo
|
|
#
|
|
# ...will monitor tank/foo fs.
|
|
#
|
|
# You can monitor zpool as well by a link on zfs_fs_<zpool>
|
|
#
|
|
# Parameters understood:
|
|
#
|
|
# config (required)
|
|
# autoconf (optional - used by munin-config)
|
|
#
|
|
# Magic markers - optional - used by installation scripts and
|
|
# munin-config:
