Notifications
|
|
=============
|
|
|
|
Notifications can be generated for several events in the image lifecycle.
|
|
These can be used for auditing, troubleshooting, etc.
|
|
|
|
Notification Drivers
|
|
--------------------
|
|
|
|
* log
|
|
|
|
This driver uses the standard Python logging infrastructure with
|
|
the notifications ending up in file specified by the log_file
|
|
configuration directive.
|
|
|
|
* messaging
|
|
|
|
This strategy sends notifications to a message queue configured
|
|
using oslo.messaging configuration options.
|
|
|
|
* noop
|
|
|
|
This strategy produces no notifications. It is the default strategy.
|
|
|
|
Notification Types
|
|
------------------
|
|
|
|
* ``image.create``
|

|
* ``image.activate``
|
|
|
|
Emitted when an image goes to `active` status. This occurs when Glance
|
|
knows where the image data is located.
|

|
|
* ``image.send``
|
|
|
|
Emitted upon completion of an image being sent to a consumer.
|
|
|
|

|
|
|
|
Emitted when an image record is updated in Glance.
|
|
|
|
* ``image.delete``
|
|
|
|
Emitted when an image deleted from Glance.
|
|
|
|
* ``task.run``
|
|
|
|
Emitted when a task is picked up by the executor to be run.
|
|
|
|
* ``task.processing``
|
|
|
|
Emitted when a task is sent over to the executor to begin processing.
|
|
|
|
* ``task.success``
|
|
