Larger values will result in more even distribution of load and less load when rebalancing the ring, but more memory usage. Number of partitions per conductor is (2^hash_partition_exponent). This determines the granularity of rebalancing: given 10 hosts, and an exponent of the 2, there are 40 partitions in the ring.A few thousand partitions should make rebalancing smooth in most cases. The default is suitable for up to a few hundred conductors. Configuring for too many partitions has a negative impact on CPU usage. hash_ring_reset_interval = 15 integer value Time (in seconds) after which the hash ring is considered outdated and is refreshed on the access. host = <based on operating system> string value Name of this node. This can be an opaque identifier. It is not necessarily a hostname, FQDN, or IP address.

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). log-date-format = %Y-%m-%d %H:%M:%S string value Defines the format string for %%(asctime)s in log records. Default: %(default)s . This option is ignored if log_config_append is set. log-dir = None string value (Optional) The base directory used for relative log_file paths. This option is ignored if log_config_append is set. log-file = None string value (Optional) Name of log file to send logging output to.

Used by oslo_log.formatters.ContextFormatter max_logfile_count = 30 integer value Maximum number of rotated log files. max_logfile_size_mb = 200 integer value Log file maximum size in MB. This option is ignored if "log_rotation_type" is not set to "size". my_ip = <based on operating system> string value IP address of this host. If unset, will determine the IP programmatically.

The default is for this option to be unset. parallel_image_downloads = False boolean value Run image downloads and raw format conversions in parallel. pecan_debug = False boolean value Enable pecan debug mode. WARNING: this is insecure and should not be used in a production environment. pin_release_version = None string value Used for rolling upgrades. Setting this option downgrades (or pins) the Bare Metal API, the internal ironic RPC communication, and the database objects to their respective versions, so they are compatible with older services. When doing a rolling upgrade from version N to version N+1, set (to pin) this to N. To unpin (default), leave it unset and the latest versions will be used. publish_errors = False boolean value Enables or disables publication of error events. pybasedir = /usr/lib/python3.6/site-packages/ironic string value Directory where the ironic python module is installed. rate_limit_burst = 0 integer value Maximum number of logged messages per rate_limit_interval. rate_limit_except_level = CRITICAL string value Log level name used by rate limiting: CRITICAL, ERROR, INFO, WARNING, DEBUG or empty string.

If running in a systemd environment you may wish to enable journal support. Doing so will use the journal native protocol which includes structured metadata in addition to log messages.This option is ignored if log_config_append is set. use-json = False boolean value Use JSON formatting for logging. This option is ignored if log_config_append is set. use-syslog = False boolean value Use syslog for logging. Existing syslog format is DEPRECATED and will be changed later to honor RFC5424. This option is ignored if log_config_append is set. use_eventlog = False boolean value Log output to Windows Event Log. use_stderr = False boolean value Log output to standard error. This option is ignored if log_config_append is set. versioned_notifications_topics = ['ironic_versioned_notifications'] list value Specifies the topics for the versioned notifications issued by Ironic. The default value is fine for most deployments and rarely needs to be changed. However, if you have a third-party service that consumes versioned notifications, it might be worth getting a topic for that service. Ironic will send a message containing a versioned notification payload to each topic queue in this list. The list of versioned notifications is visible in https://docs.openstack.org/ironic/latest/admin/notifications.html watch-log-file = False boolean value Uses logging handler designed to watch file system. When log file is moved or removed this handler will open a new log file with specified path instantaneously. It makes sense only if log_file option is specified and Linux platform is used. This option is ignored if log_config_append is set. 5.1.2. agent The following table outlines the options available under the [agent] group in the /etc/ironic/ironic.conf file.

By streaming raw images directly onto the disk the agent ramdisk will not spend time copying the image to a tmpfs partition (therefore consuming less memory) prior to writing it to the disk. Unless the disk where the image will be copied to is really slow, this option should be set to True.

Service tokens are allowed to request that an expired token can be used and so this check should tightly control that only actual services should be sending this token. Roles here are applied as an ANY check so any role in this list must be present. For backwards compatibility reasons this currently only affects the allow_expired check. service_token_roles_required = False boolean value For backwards compatibility reasons we must let valid service tokens pass that don't pass the service_token_roles check as valid.
