# Plugin to monitor quota on a specified device. Needs repquota and root privs
#
# Usage: place in /etc/munin/node.d/quota-usage_<dev> (or link it there using
# ln -s), for example quota-usage_hda3. Use underscores instead of slashes, for
# example to monitor /dev/mapper/vol-foo, name this quota-usage_mapper_vol-foo
#
# Parameters understood:
#
# config (required)
#
#%# family=manual

# So to monitor /dev/mapper/vol-foo use quota-usage_mapper_vol-foo
