Description of RabbitMQ configuration options

Configuration option = Default value	Description
[oslo_messaging_rabbit]
amqp_auto_delete = False	(Boolean) Auto-delete queues in AMQP.
amqp_durable_queues = False	(Boolean) Use durable queues in AMQP.

default_notification_exchange = ${control_exchange}_notification	(String) Exchange name for for sending notifications
default_notification_retry_attempts = -1	(Integer) Reconnecting retry count in case of connectivity problem during sending notification, -1 means infinite retry.
default_rpc_exchange = ${control_exchange}_rpc	(String) Exchange name for sending RPC messages
default_rpc_retry_attempts = -1	(Integer) Reconnecting retry count in case of connectivity problem during sending RPC message, -1 means infinite retry. If actual retry attempts in not 0 the rpc request could be processed more then one time
fake_rabbit = False	(Boolean) Deprecated, use rpc_backend=kombu+memory or rpc_backend=fake
frame_max = None	(Integer) The maximum byte size for an AMQP frame
heartbeat_interval = 1	(Integer) How often to send heartbeats for consumer's connections
heartbeat_rate = 2	(Integer) How often times during the heartbeat_timeout_threshold we check the heartbeat.
heartbeat_timeout_threshold = 60	(Integer) Number of seconds after which the Rabbit broker is considered down if heartbeat's keep-alive fails (0 disable the heartbeat). EXPERIMENTAL
host_connection_reconnect_delay = 0.25	(Floating point) Set delay for reconnection to some host which has connection error
kombu_compression = None	(String) EXPERIMENTAL: Possible values are: gzip, bz2. If not set compression will not be used. This option may notbe available in future versions.
kombu_failover_strategy = round-robin	(String) Determines how the next RabbitMQ node is chosen in case the one we are currently connected to becomes unavailable. Takes effect only if more than one RabbitMQ node is provided in config.
kombu_missing_consumer_retry_timeout = 60	(Integer) How long to wait a missing client before abandoning to send it its replies. This value should not be longer than rpc_response_timeout.
kombu_reconnect_delay = 1.0	(Floating point) How long to wait before reconnecting in response to an AMQP consumer cancel notification.
kombu_ssl_ca_certs =	(String) SSL certification authority file (valid only if SSL enabled).
kombu_ssl_certfile =	(String) SSL cert file (valid only if SSL enabled).
kombu_ssl_keyfile =	(String) SSL key file (valid only if SSL enabled).
kombu_ssl_version =	(String) SSL version to use (valid only if SSL enabled). Valid values are TLSv1 and SSLv23. SSLv2, SSLv3, TLSv1_1, and TLSv1_2 may be available on some distributions.
notification_listener_prefetch_count = 100	(Integer) Max number of not acknowledged message which RabbitMQ can send to notification listener.
notification_persistence = False	(Boolean) Persist notification messages.
notification_retry_delay = 0.25	(Floating point) Reconnecting retry delay in case of connectivity problem during sending notification message
pool_max_overflow = 0	(Integer) Maximum number of connections to create above pool_max_size.
pool_max_size = 10	(Integer) Maximum number of connections to keep queued.
pool_recycle = 600	(Integer) Lifetime of a connection (since creation) in seconds or None for no recycling. Expired connections are closed on acquire.
pool_stale = 60	(Integer) Threshold at which inactive (since release) connections are considered stale in seconds or None for no staleness. Stale connections are closed on acquire.
pool_timeout = 30	(Integer) Default number of seconds to wait for a connections to available
rabbit_ha_queues = False	(Boolean) Try to use HA queues in RabbitMQ (x-ha-policy: all). If you change this option, you must wipe the RabbitMQ database. In RabbitMQ 3.0, queue mirroring is no longer controlled by the x-ha-policy argument when declaring a queue. If you just want to make sure that all queues (except those with auto-generated names) are mirrored across all nodes, run: "rabbitmqctl set_policy HA '^(?!amq.).*' '{"ha-mode": "all"}' "
rabbit_host = localhost	(String) The RabbitMQ broker address where a single node is used.
rabbit_hosts = $rabbit_host:$rabbit_port	(List) RabbitMQ HA cluster host:port pairs.
rabbit_interval_max = 30	(Integer) Maximum interval of RabbitMQ connection retries. Default is 30 seconds.
rabbit_login_method = AMQPLAIN	(String) The RabbitMQ login method.
rabbit_max_retries = 0	(Integer) Maximum number of RabbitMQ connection retries. Default is 0 (infinite retry count).

rabbit_port = 5672	(Port number) The RabbitMQ broker port where a single node is used.
rabbit_qos_prefetch_count = 0	(Integer) Specifies the number of messages to prefetch. Setting to zero allows unlimited messages.
