# lib/ceilometer

 # Install and start **Ceilometer** service
 

 # To enable a minimal set of Ceilometer services, add the following to localrc:

 #

 #   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:

 #

 #   enable_service ceilometer-alarm-notifier ceilometer-alarm-evaluator

 # 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
