Configuration Options

Ceilometer specific

The following table lists the ceilometer specific options in the global configuration file. Please note that ceilometer uses openstack-common extensively, which requires that the other parameters are set appropriately. For information we are listing the configuration elements that we use after the ceilometer specific elements.

If you use sql alchemy, its specific paramaters will need to be set.

Parameter	Default	Note
nova_control_exchange	nova	Exchange name for Nova notifications
glance_control_exchange	glance	Exchange name for Glance notifications

counter_source	openstack	The source name of emited counters
control_exchange	ceilometer	AMQP exchange to connect to if using RabbitMQ or Qpid
periodic_interval	600	seconds between running periodic tasks
os-username	ceilometer	Username to use for openstack service access
os-password os-tenant-id	admin	Password to use for openstack service access Tenant ID to use for openstack service access
os-tenant-name	admin	Tenant name to use for openstack service access
os-auth-url	http://localhost:5000/v2.0	Auth URL to use for openstack service access
database_connection	mongodb://localhost:27017/ceilometer	Database connection string
