# lib/ceilometer
# 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
#
# 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: Seconds between pipeline processing runs. Default 600.
# CEILOMETER_BACKEND: Database backend (e.g. 'mysql', 'mongodb', 'es')
# CEILOMETER_COORDINATION_URL: URL for group membership service provided by tooz.
# CEILOMETER_EVENTS: Enable event collection
# Dependencies:
#
# - functions
# - OS_AUTH_URL for auth in api
# - DEST set to the destination directory
# - SERVICE_PASSWORD, SERVICE_TENANT_NAME for auth in api
# - STACK_USER service user
# stack.sh
