|
|
#
|
|
# 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)

#
|
|
# ** WARNING **
|
|
# For now this plugin does not allow "_" in the name of a zpool or filesystems
|
