#
# This class is used to specify configuration parameters that are common
# across all ceilometer services.
#
# === Parameters:

# (Required) Secret key for signing messages.
#
# [*package_ensure*]
# (Optional) ensure state for package.

# (Optional) Maximum number of parallel requests for services to handle at
# the same time.
# Defaults to $facts['os_service_default']
#
# [*notification_transport_url*]
# (optional) A URL representing the messaging driver to use for notifications
# and its full configuration. Transport URLs take the form:
# transport://user:pass@host1:port[,hostN:portN]/virtual_host
# Defaults to $facts['os_service_default']
#
# [*notification_topics*]
# (Optional) AMQP topic used for OpenStack notifications (list value)
# Defaults to $facts['os_service_default']
#
# [*notification_driver*]
# (optional) Driver or drivers to handle sending notifications.
# Value can be a string or a list.
# Defaults to $facts['os_service_default']
#
# [*notification_retry*]
# (Optional) The maximum number of attempts to re-sent a notification
# message, which failed to be delivered due to a recoverable error.
# Defaults to $facts['os_service_default'].
#
# [*executor_thread_pool_size*]
# (optional) Size of executor thread pool when executor is threading or eventlet.
# Defaults to $facts['os_service_default'].
#
# [*default_transport_url*]
# (optional) A URL representing the messaging driver to use and its full
# configuration. Transport URLs take the form:
# transport://user:pass@host1:port[,hostN:portN]/virtual_host
# Defaults to $facts['os_service_default']

# [*rpc_response_timeout*]
# (Optional) Seconds to wait for a response from a call.
# Defaults to $facts['os_service_default']
#
# [*control_exchange*]
# (Optional) The default exchange under which topics are scoped. May be
# overridden by an exchange name specified in the transport_url
# option.
# Defaults to $facts['os_service_default']

# [*rabbit_ha_queues*]
# (Optional) Use HA queues in RabbitMQ (x-ha-policy: all). If you change this
# option, you must wipe the RabbitMQ database. (boolean value)
# Defaults to $facts['os_service_default']
#
# [*rabbit_quorum_queue*]
# (Optional) Use quorum queues in RabbitMQ.
# Defaults to $facts['os_service_default']

# Defaults to $facts['os_service_default']
#
# [*rabbit_transient_queues_ttl*]
# (Optional) Positive integer representing duration in seconds for
# queue TTL (x-expires). Queues which are unused for the duration
# of the TTL are automatically deleted.
# The parameter affects only reply and fanout queues. (integer value)
# Min to 1
# Defaults to $facts['os_service_default']
#
# [*rabbit_quorum_delivery_limit*]
# (Optional) Each time a message is rdelivered to a consumer, a counter is
# incremented. Once the redelivery count exceeds the delivery limit
# the message gets dropped or dead-lettered.
# Defaults to $facts['os_service_default']

# (Optional) Enable x-cancel-on-ha-failover flag so that rabbitmq server will
# cancel and notify consumers when queue is down.
# Defaults to $facts['os_service_default']
#
# [*rabbit_heartbeat_timeout_threshold*]
