# Plugin to monitor ZFS Filesystems
|
|
# Author: Adam Michel (elfurbe@furbism.com)
|
|
# Description:
|
|
# This is an extension of the zfs_fs plugin
|
|
# modified as a multigraph to graph all zfs
|
|
# filesystems it can find
|
|
#
|
|
# Tested on Ubuntu-14.04
|
|
#
|
|
# Parameters understood:
|
|
#
|
|
# config (required)
|
|
# autoconf (optional - used by munin-config)
|
