# 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
|
|
# #%# capabilities=autoconf suggest
