Description of ZeroMQ configuration options

Configuration option = Default value	Description
[DEFAULT]
rpc_zmq_bind_address = *	(String) ZeroMQ bind address. Should be a wildcard (*), an ethernet interface, or IP. The "host" option should point or resolve to this address.
rpc_zmq_bind_port_retries = 100	(Integer) Number of retries to find free port number before fail with ZMQBindError.
rpc_zmq_contexts = 1	(Integer) Number of ZeroMQ contexts, defaults to 1.
rpc_zmq_host = localhost	(String) Name of this node. Must be a valid hostname, FQDN, or IP address. Must match "host" option, if running Nova.
rpc_zmq_ipc_dir = /var/run/openstack	(String) Directory for holding IPC sockets.
rpc_zmq_matchmaker = redis	(String) MatchMaker driver.
rpc_zmq_max_port = 65536	(Integer) Maximal port number for random ports range.
rpc_zmq_min_port = 49153	(Port number) Minimal port number for random ports range.
rpc_zmq_serialization = json	(String) Default serialization mechanism for serializing/deserializing outgoing/incoming messages
rpc_zmq_topic_backlog = None	(Integer) Maximum number of ingress messages to locally buffer per topic. Default is unlimited.
use_pub_sub = True	(Boolean) Use PUB/SUB pattern for fanout methods. PUB/SUB always uses proxy.
zmq_immediate = False	(Boolean) This option configures round-robin mode in zmq socket. True means not keeping a queue when server side disconnects. False means to keep queue and messages even if server is disconnected, when the server appears we send all accumulated messages to it.
zmq_target_expire = 300	(Integer) Expiration timeout in seconds of a name service record about existing target ( < 0 means no timeout).
zmq_target_update = 180	(Integer) Update period in seconds of a name service record about existing target.
[oslo_messaging_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_poll_timeout = 1	(Integer) The default number of seconds that poll should wait. Poll raises timeout exception when timeout expired.
rpc_zmq_bind_address = *	(String) ZeroMQ bind address. Should be a wildcard (*), an ethernet interface, or IP. The "host" option should point or resolve to this address.
rpc_zmq_bind_port_retries = 100	(Integer) Number of retries to find free port number before fail with ZMQBindError.
rpc_zmq_contexts = 1	(Integer) Number of ZeroMQ contexts, defaults to 1.
rpc_zmq_host = localhost	(String) Name of this node. Must be a valid hostname, FQDN, or IP address. Must match "host" option, if running Nova.
rpc_zmq_ipc_dir = /var/run/openstack	(String) Directory for holding IPC sockets.
rpc_zmq_matchmaker = redis	(String) MatchMaker driver.
rpc_zmq_max_port = 65536	(Integer) Maximal port number for random ports range.
rpc_zmq_min_port = 49153	(Port number) Minimal port number for random ports range.
rpc_zmq_serialization = json	(String) Default serialization mechanism for serializing/deserializing outgoing/incoming messages
rpc_zmq_topic_backlog = None	(Integer) Maximum number of ingress messages to locally buffer per topic. Default is unlimited.
use_pub_sub = True	(Boolean) Use PUB/SUB pattern for fanout methods. PUB/SUB always uses proxy.
use_router_proxy = True	(Boolean) Use ROUTER remote proxy.
zmq_immediate = False	(Boolean) This option configures round-robin mode in zmq socket. True means not keeping a queue when server side disconnects. False means to keep queue and messages even if server is disconnected, when the server appears we send all accumulated messages to it.
zmq_target_expire = 300	(Integer) Expiration timeout in seconds of a name service record about existing target ( < 0 means no timeout).
zmq_target_update = 180	(Integer) Update period in seconds of a name service record about existing target.
