Description of RPC configuration options

Configuration option = Default value	Description
[DEFAULT]
rpc_backend = rabbit	(String) The messaging driver to use, defaults to rabbit. Other drivers include amqp and zmq.
rpc_cast_timeout = -1	(Integer) Seconds to wait before a cast expires (TTL). The default value of -1 specifies an infinite linger period. The value of 0 specifies no linger period. Pending messages shall be discarded immediately when the socket is closed. Only supported by impl_zmq.
rpc_conn_pool_size = 30	(Integer) Size of RPC connection pool.
rpc_poll_timeout = 1	(Integer) The default number of seconds that poll should wait. Poll raises timeout exception when timeout expired.
rpc_response_timeout = 60	(Integer) Seconds to wait for a response from a call.
[notification]
messaging_urls = []	(Multi-valued) Messaging URLs to listen for notifications. Example: transport://user:pass@host1:port[,hostN:portN]/virtual_host (DEFAULT/transport_url is used if empty)
[oslo_concurrency]
disable_process_locking = False	(Boolean) Enables or disables inter-process locks.
lock_path = None	(String) Directory to use for lock files. For security, the specified directory should only be writable by the user running the processes that need locking. Defaults to environment variable OSLO_LOCK_PATH. If external locks are used, a lock path must be set.
[oslo_messaging_amqp]
allow_insecure_clients = False	(Boolean) Accept clients using either SSL or plain TCP
broadcast_prefix = broadcast	(String) address prefix used when broadcasting to all servers
container_name = None	(String) Name for the AMQP container
group_request_prefix = unicast	(String) address prefix when sending to any server in group
idle_timeout = 0	(Integer) Timeout for inactive connections (in seconds)
password =	(String) Password for message broker authentication
sasl_config_dir =	(String) Path to directory that contains the SASL configuration
sasl_config_name =	(String) Name of configuration file (without .conf suffix)
sasl_mechanisms =	(String) Space separated list of acceptable SASL mechanisms
server_request_prefix = exclusive	(String) address prefix used when sending to a specific server
ssl_ca_file =	(String) CA certificate PEM file to verify server certificate
ssl_cert_file =	(String) Identifying certificate PEM file to present to clients
ssl_key_file =	(String) Private key PEM file used to sign cert_file certificate
ssl_key_password = None	(String) Password for decrypting ssl_key_file (if encrypted)
trace = False	(Boolean) Debug: dump AMQP frames to stdout
username =	(String) User name for message broker authentication
[oslo_messaging_notifications]
driver = []	(Multi-valued) The Drivers(s) to handle sending notifications. Possible values are messaging, messagingv2, routing, log, test, noop
topics = notifications	(List) AMQP topic used for OpenStack notifications.
transport_url = None	(String) A URL representing the messaging driver to use for notifications. If not set, we fall back to the same configuration used for RPC.
[oslo_messaging_rabbit]
rpc_listener_prefetch_count = 100	(Integer) Max number of not acknowledged message which RabbitMQ can send to rpc listener.
rpc_queue_expiration = 60	(Integer) Time to live for rpc queues without consumers in seconds.
rpc_reply_exchange = ${control_exchange}_rpc_reply	(String) Exchange name for receiving RPC replies
rpc_reply_listener_prefetch_count = 100	(Integer) Max number of not acknowledged message which RabbitMQ can send to rpc reply listener.
rpc_reply_retry_attempts = -1	(Integer) Reconnecting retry count in case of connectivity problem during sending reply. -1 means infinite retry during rpc_timeout
rpc_reply_retry_delay = 0.25	(Floating point) Reconnecting retry delay in case of connectivity problem during sending reply.
rpc_retry_delay = 0.25	(Floating point) Reconnecting retry delay in case of connectivity problem during sending RPC message
socket_timeout = 0.25	(Floating point) Set socket timeout in seconds for connection's socket
ssl = None	(Boolean) Enable SSL
ssl_options = None	(Dict) Arguments passed to ssl.wrap_socket
tcp_user_timeout = 0.25	(Floating point) Set TCP_USER_TIMEOUT in seconds for connection's socket
[publisher]
telemetry_secret = change this for valid signing	(String) Secret value for signing messages. Set value empty if signing is not required to avoid computational overhead.
[publisher_notifier]
event_topic = event	(String) The topic that ceilometer uses for event notifications.
metering_topic = metering	(String) The topic that ceilometer uses for metering notifications.
telemetry_driver = messagingv2	(String) The driver that ceilometer uses for metering notifications.
