- service_token_roles¶

- 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 memory bytes used by the quorum queue. Used only when rabbit_quorum_queue is enabled, Default 0 which means dont set a limit.

rabbit_quroum_max_memory_bytes
- 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.
- 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
oslo_policy¶
- enforce_scope¶
- Type
boolean
- Default
False
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.
- enforce_new_defaults¶
- Type
boolean
- Default
False
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.json

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¶

- 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.
