[RFE] Add notification support to ironic

[Vladyslav Drok]

Ironic has a need for inter-service notifications. Near real-time inter-service notifications in OpenStack have a variety of use cases. At the Mitaka design summit, some of the use cases discussed for ironic included integration with billing systems, using notifications to support an operations panel to keep track of potential failures, and integration with TripleO. The linked specification outlines a general framework for a notification schema in ironic.

Specification has been approved and is available at http://specs.openstack.org/openstack/ironic-specs/specs/approved/notifications.html.

I will have time to work on implementing starting in early to mid March 2016.

[Chris Austin (jcaustin)]

I've begun implementing this per the spec. I will open reviews within the week.

Great to see this work in progress! Just adding a comment to let you know that we (the Searchlight team [0]) have now received a few requests to provide search support for ironic. Notifications are a pre-requisite for us to do anything and providing enough data so that we don't have to do any API callbacks to get extra information at the time we index a resource is ideal for performant indexing.

    Add power state change notifications

    This adds optional notifications emitted when ironic changes a node's power
    state or when ironic detects a change in a node's power state.

    These notifications can be consumed by any external service listening to the
    message bus to perform functions like tracking node power state changes over
    time or automatically responding to anomalous power states.

    The event_types of the new notifications are:

    * baremetal.node.power_set.{start,end,error}
    * baremetal.node.power_state_corrected.success

    This also adds a new NodePayload class for notification payloads related
    to nodes.

    Add notification documentation to administrator's guide

    This moves the description of available notifications in ironic to the
    administrator's guide and briefly describes how to configure
    notifications. It also documents the message bus topic ironic
    notifications are emitted on, since previously that required looking at
    code to find out.
