# Plugin to monitor used size of a tenant in glance
#
# To monitor the used size of a tenant in glance do:
# E.g.
# ln -s /usr/share/munin/plugins/glance_size_ /etc/munin/plugins/glance_size_<tenant_uuid>
#
# Needs following minimal configuration in plugin-conf.d/glance:
# [glance_*]
# user glance
#
# To show tenant name plugin must run as root
#
# Magic markers
