----------------------
Descriptions of notifications emitted by ironic will be documented here when
they are added.
Available notifications
=======================
.. TODO(mariojv) Move the below to deployer documentation.
.. TODO(mariojv) Match Nova's tabular formatting below.
The notifications that ironic emits are described here. They are listed
(alphabetically) by service first, then by event_type.
------------------------------
ironic-conductor notifications
------------------------------
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::
{
"priority": "info",
"payload":{
"ironic_object.namespace":"ironic",
"ironic_object.name":"NodeSetPowerStatePayload",
"ironic_object.version":"1.0",
"ironic_object.data":{

}
},
"event_type":"baremetal.node.power_set.start",
"publisher_id":"ironic-conductor.hostname01"
}
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::
{
"priority": "info",
"payload":{
"ironic_object.namespace":"ironic",

Adds notifications for:
* when ironic attempts to set the power state on the node (notifications
with event type "baremetal.node.power_set.{start, end, error}")
* when ironic detects the power state on baremetal hardware has changed
and updates the node in the database appropriately (notifications with
event type "baremetal.node.power_state_corrected.success")
These are emitted if notifications are enabled. For more details, see the
developer documentation.
