This option can be changed without restarting.
If set to true, the logging level will be set to DEBUG instead of the default INFO level.
- log_config_append¶
- Type:
string
- Default:
<None>
- Mutable:
This option can be changed without restarting.
The name of a logging configuration file. This file is appended to any existing logging configuration files. For details about logging configuration files, see the Python logging module documentation. Note that when logging configuration files are used then all logging configuration is set in the configuration file and other logging configuration options are ignored (for example, log-date-format).

DEFAULT
log_config
- log_date_format¶
- Type:
string

- log_file¶
- Type:
string
- Default:
<None>
(Optional) Name of log file to send logging output to. If no default is set, logging will go to stderr as defined by use_stderr. This option is ignored if log_config_append is set.

- ssl_enforce_fips_mode¶
- Type:
boolean
- Default:
False
Global toggle for enforcing the OpenSSL FIPS mode. This feature requires Python support. This is available in Python 3.9 in all environments and may have been backported to older Python versions on select environments. If the Python executable used does not support OpenSSL FIPS mode, an exception will be raised.
- heartbeat_in_pthread¶
- Type:
boolean
- Default:
False
(DEPRECATED) It is recommend not to use this option anymore. Run the health check heartbeat thread through a native python thread by default. If this option is equal to False then the health check heartbeat will inherit the execution model from the parent process. For example if the parent process has monkey patched the stdlib by using eventlet/greenlet then the heartbeat will be run through a green thread. This option should be set to True only for the wsgi services.
Warning
This option is deprecated for removal. Its value may be silently ignored in the future.
- Reason:
The option is related to Eventlet which will be removed. In addition this has never worked as expected with services using eventlet for core service framework.

- rabbit_ha_queues¶
- Type:
boolean
- Default:
False
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_ha_queues
- rabbit_quorum_queue¶
- Type:
boolean
- Default:
False
Use quorum queues in RabbitMQ (x-queue-type: quorum). The quorum queue is a modern queue type for RabbitMQ implementing a durable, replicated FIFO queue based on the Raft consensus algorithm. It is available as of RabbitMQ 3.8.0. If set this option will conflict with the HA queues (
rabbit_ha_queues
) aka mirrored queues, in other words the HA queues should be disabled. Quorum queues are also durable by default so the amqp_durable_queues option is ignored when this option is enabled.
- rabbit_transient_quorum_queue¶
- Type:
boolean
- Default:
False
Use quorum queues for transients queues in RabbitMQ. Enabling this option will then make sure those queues are also using quorum kind of rabbit queues, which are HA by default.
- rabbit_quorum_delivery_limit¶
- Type:
integer
- Default:
0
Each time a message is redelivered to a consumer, a counter is incremented. Once the redelivery count exceeds the delivery limit the message gets dropped or dead-lettered (if a DLX exchange has been configured) Used only when rabbit_quorum_queue is enabled, Default 0 which means dont set a limit.
- rabbit_quorum_max_memory_length¶
- Type:
integer
- Default:
0
By default all messages are maintained in memory if a quorum queue grows in length it can put memory pressure on a cluster. This option can limit the number of messages in the quorum queue. Used only when rabbit_quorum_queue is enabled, Default 0 which means dont set a limit.

- rabbit_transient_queues_ttl¶
- Type:
integer
- Default:
1800
- Minimum Value:
0
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. Setting 0 as value will disable the x-expires. If doing so, make sure you have a rabbitmq policy to delete the queues or you deployment will create an infinite number of queue over time.In case rabbit_stream_fanout is set to True, this option will control data retention policy (x-max-age) for messages in the fanout queue rather then the queue duration itself. So the oldest data in the stream queue will be discarded from it once reaching TTL Setting to 0 will disable x-max-age for stream which make stream grow indefinitely filling up the diskspace
- rabbit_qos_prefetch_count¶
- Type:
integer
- Default:
0
Specifies the number of messages to prefetch. Setting to zero allows unlimited messages.
- heartbeat_timeout_threshold¶
- Type:
integer
- Default:
60
Number of seconds after which the Rabbit broker is considered down if heartbeat’s keep-alive fails (0 disables heartbeat).
- heartbeat_rate¶
- Type:
integer
- Default:
3
How often times during the heartbeat_timeout_threshold we check the heartbeat.
- direct_mandatory_flag¶
- Type:
boolean
- Default:
True
(DEPRECATED) Enable/Disable the RabbitMQ mandatory flag for direct send. The direct send is used as reply, so the MessageUndeliverable exception is raised in case the client queue does not exist.MessageUndeliverable exception will be used to loop for a timeout to lets a chance to sender to recover.This flag is deprecated and it will not be possible to deactivate this functionality anymore
Warning
This option is deprecated for removal. Its value may be silently ignored in the future.
- Reason:
Mandatory flag no longer deactivable.
- enable_cancel_on_failover¶
- Type:
boolean
- Default:
False
Enable x-cancel-on-ha-failover flag so that rabbitmq server will cancel and notify consumerswhen queue is down
- use_queue_manager¶
- Type:
boolean
- Default:
False
Should we use consistant queue names or random ones
- hostname¶
- Type:
string
- Default:
node1.example.com
This option has a sample default set, which means that its actual default value may vary from the one documented above.
Hostname used by queue manager. Defaults to the value returned by socket.gethostname().
- processname¶
- Type:
string
- Default:
nova-api
This option has a sample default set, which means that its actual default value may vary from the one documented above.
Process name used by queue manager
- rabbit_stream_fanout¶
- Type:
boolean
- Default:
False
Use stream queues in RabbitMQ (x-queue-type: stream). Streams are a new persistent and replicated data structure (“queue type”) in RabbitMQ which models an append-only log with non-destructive consumer semantics. It is available as of RabbitMQ 3.9.0. If set this option will replace all fanout queues with only one stream queue.
oslo_middleware¶
- enable_proxy_headers_parsing¶
- Type:
boolean
- Default:
False
Whether the application is behind a proxy or not. This determines if the middleware should parse the headers or not.
oslo_policy¶
- enforce_scope¶
- Type:
boolean
- Default:
True
This option controls whether or not to enforce scope when evaluating policies. If
True
, the scope of the token used in the request is compared to thescope_types
of the policy being enforced. If the scopes do not match, anInvalidScope
exception will be raised. IfFalse
, a message will be logged informing operators that policies are being invoked with mismatching scope.Warning
This option is deprecated for removal. Its value may be silently ignored in the future.
- Reason:
This configuration was added temporarily to facilitate a smooth transition to the new RBAC. OpenStack will always enforce scope checks. This configuration option is deprecated and will be removed in the 2025.2 cycle.
- enforce_new_defaults¶
- Type:
boolean
- Default:
True
This option controls whether or not to use old deprecated defaults when evaluating policies. If
True
, the old deprecated defaults are not going to be evaluated. This means if any existing token is allowed for old defaults but is disallowed for new defaults, it will be disallowed. It is encouraged to enable this flag along with theenforce_scope
flag so that you can get the benefits of new defaults andscope_type
together. IfFalse
, the deprecated policy check string is logically OR’d with the new policy check string, allowing for a graceful upgrade experience between releases with new policies, which is the default behavior.
- policy_file¶
- Type:
string
- Default:
policy.yaml
The relative or absolute path of a file that maps roles to permissions for a given service. Relative paths must be specified in relation to the configuration file setting this option.
- policy_default_rule¶

- Type:
boolean
- Default:
False
Enable the profiling for all services on this node.
Default value is False (fully disable the profiling feature).

- trace_sqlalchemy¶
- Type:
boolean
- Default:
False
Enable SQL requests profiling in services.
Default value is False (SQL requests won’t be traced).
Possible values:
True: Enables SQL requests profiling. Each SQL query will be part of the trace and can the be analyzed by how much time was spent for that.
False: Disables SQL requests profiling. The spent time is only shown on a higher level of operations. Single SQL queries cannot be analyzed this way.
- trace_requests¶
- Type:
boolean
- Default:
False
Enable python requests package profiling.
Supported drivers: jaeger+otlp
Default value is False.
Possible values:
True: Enables requests profiling.
False: Disables requests profiling.
- hmac_keys¶
- Type:
string
- Default:
SECRET_KEY
Secret key(s) to use for encrypting context data for performance profiling.
This string value should have the following format: <key1>[,<key2>,…<keyn>], where each key is some random string. A user who triggers the profiling via the REST API has to set one of these keys in the headers of the REST API call to include profiling results of this node for this particular project.
Both “enabled” flag and “hmac_keys” config options should be set to enable profiling. Also, to generate correct profiling information across all services at least one key needs to be consistent between OpenStack projects. This ensures it can be used from client side to generate the trace, containing information from all possible resources.
- connection_string¶
- Type:
