 # Install and start **Ceilometer** service

 # To enable a minimal set of Ceilometer services, add the following to the
 # localrc section of local.conf:
 #
 #   enable_service ceilometer-acompute ceilometer-acentral ceilometer-anotification ceilometer-collector ceilometer-api
 #
 # To ensure Ceilometer alarming services are enabled also, further add to the
 # localrc section of local.conf:
 #
 #   enable_service ceilometer-alarm-notifier ceilometer-alarm-evaluator
 #
 # To ensure events are stored, add the following section to local.conf:
 #
 #   [[post-config|$CEILOMETER_CONF]]
 #   [notification]
 #   store_events=True
 #
 # Several variables set in the localrc section adjust common behaviors
 # of Ceilometer (see within for additional settings):
 #
 #   CEILOMETER_USE_MOD_WSGI:       When True, run the api under mod_wsgi.
 #   CEILOMETER_PIPELINE_INTERVAL:  The number of seconds between pipeline processing
 #                                  runs. Default 600.
 #   CEILOMETER_BACKEND:            The database backend (e.g. 'mysql', 'mongodb')
 #   CEILOMETER_COORDINATION_URL:   The URL for a group membership service provided
 #                                  by tooz.
