Notifications

Ironic, when configured to do so, will emit notifications over a
message bus that indicate different events that occur within the
service. These can be consumed by any external service. Examples may
include a billing or usage system, a monitoring data store, or other
OpenStack services. This page describes how to enable notifications and
the different kinds of notifications that ironic may emit. The external
consumer will see notifications emitted by ironic as JSON objects
structured in the following manner:

{
    "priority": <string, defined by the sender>,
    "event_type": <string, defined by the sender>,
    "timestamp": <string, the isotime of when the notification emitted>,
    "publisher_id": <string, defined by the sender>,
    "message_id": <uuid, generated by oslo>,
    "payload": <json serialized dict, defined by the sender>
}

Configuration

To enable notifications with ironic, there are two configuration
options in ironic.conf that must be adjusted.

The first option is the notification_level option in the
[DEFAULT] section of the configuration file. This can be
set to “debug”, “info”, “warning”, “error”, or “critical”, and
determines the minimum priority level for which notifications are
emitted. For example, if the option is set to “warning”, all
notifications with priority level “warning”, “error”, or “critical” are
emitted, but not notifications with priority level “debug” or “info”.
For information about the semantics of each log level, see the OpenStack
logging standards1. If this option is unset, no
notifications will be emitted. The priority level of each available
notification is documented below.

The second option is the transport_url option in the
[oslo_messaging_notifications] section of the
configuration. This determines the message bus used when sending
notifications. If this is unset, the default transport used for RPC is
used.

All notifications are emitted on the “ironic_versioned_notifications”
topic in the message bus. Generally, each type of message that traverses
the message bus is associated with a topic describing what the message
is about. For more information, see the documentation of your chosen
message bus, such as the RabbitMQ documentation2.

Note that notifications may be lossy, and there’s no guarantee that a
notification will make it across the message bus to a consumer.

Versioning

Each notification has an associated version in the
“ironic_object.version” field of the payload. Consumers are guaranteed
that microversion bumps will add new fields, while macroversion bumps
are backwards-incompatible and may have fields removed.

Versioned notifications are emitted by default to the ironic_versioned_notifications topic. This can
be changed and it is configurable in the ironic.conf with the versioned_notifications_topics config
option.

Available notifications

The notifications that ironic emits are described here. They are
listed (alphabetically) by service first, then by event_type. All
examples below show payloads before serialization to JSON.

ironic-api notifications

Resources CRUD notifications

These notifications are emitted from API service when ironic
resources are modified as part of create, update, or delete (CRUD)3 procedures. All CRUD notifications
are emitted at INFO level, except for “error” status that is emitted at
ERROR level.

ironic-conductor
notifications

Node console notifications

These notifications are emitted by the ironic-conductor service when
conductor service starts or stops console for the node. The notification
event types for a node console are:

  • baremetal.node.console_set.start
  • baremetal.node.console_set.end
  • baremetal.node.console_set.error
  • baremetal.node.console_restore.start
  • baremetal.node.console_restore.end
  • baremetal.node.console_restore.error

console_set action is used when start or stop console is
initiated. The console_restore action is used when the
console was already enabled, but a driver must restart the console
because an ironic-conductor was restarted. This may also be sent when an
ironic-conductor takes over a node that was being managed by another
ironic-conductor. “start” and “end” notifications have INFO level,
“error” has ERROR. Example of node console notification:

baremetal.node.power_set

  • baremetal.node.power_set.start is emitted by the
    ironic-conductor service when it begins a power state change. It has
    notification level “info”.
  • baremetal.node.power_set.end is emitted when
    ironic-conductor successfully completes a power state change task. It
    has notification level “info”.
  • baremetal.node.power_set.error is emitted by
    ironic-conductor when it fails to set a node’s power state. It has
    notification level “error”. This can occur when ironic fails to retrieve
    the old power state prior to setting the new one on the node, or when it
    fails to set the power state if a change is requested.

Here is an example payload for a notification with this event type.
The “to_power” payload field indicates the power state to which the
ironic-conductor is attempting to change the node:

baremetal.node.power_state_corrected

  • baremetal.node.power_state_corrected.success is emitted
    by ironic-conductor when the power state on the baremetal hardware is
    different from the previous known power state of the node and the
    database is corrected to reflect this new power state. It has
    notification level “info”.

Here is an example payload for a notification with this event_type.
The “from_power” payload field indicates the previous power state on the
node, prior to the correction:

baremetal.node.provision_set

  • baremetal.node.provision_set.start is emitted by the
    ironic-conductor service when it begins a provision state transition. It
    has notification level INFO.
  • baremetal.node.provision_set.end is emitted when
    ironic-conductor successfully completes a provision state transition. It
    has notification level INFO.
  • baremetal.node.provision_set.success is emitted when
    ironic-conductor successfully changes provision state instantly, without
    any intermediate work required (example is AVAILABLE to MANAGEABLE). It
    has notification level INFO.
  • baremetal.node.provision_set.error is emitted by
    ironic-conductor when it changes provision state as result of error
    event processing. It has notification level ERROR.

Here is an example payload for a notification with this event type.
The “previous_provision_state” and “previous_target_provision_state”
payload fields indicate a node’s provision states before state change,
“event” is the FSM (finite state machine) event that triggered the state
change:
