Actions
|

|
|
=======

|

|
|
An ``Action`` is what enables Watcher to transform the current state of a
|
||
|
|
``Cluster`` after an ``Audit``.
|
||
|
|
|
||
|
|
An ``Action`` is an atomic task which changes the current state of a target
|
||
|
|
Managed resource of the OpenStack ``Cluster`` such as:
|
||
|
|
|
||
|
|
- Live migration of an instance from one compute node to another compute
|
||
|
|
node with Nova
|
||
|
|
- Changing the power level of a compute node (ACPI level, ...)
|
||
|
|
- Changing the current state of a compute node (enable or disable) with Nova
|
||
|
|
|
||
|
|
In most cases, an ``Action`` triggers some concrete commands on an existing
|
||
|
|
OpenStack module (Nova, Neutron, Cinder, Ironic, etc.).
|
||
|
|
|
||
|
|
An ``Action`` has a life-cycle and its current state may be one of the
|
||
|
|
following:
|
||
|
|
|
||
|
|
- **PENDING** : the ``Action`` has not been executed yet by the
|
||
|
|
``Watcher Applier``.
|
||
|
|
- **ONGOING** : the ``Action`` is currently being processed by the
|
||
|
|
``Watcher Applier``.
|
||
|
|
- **SUCCEEDED** : the ``Action`` has been executed successfully
|
||
|
|
- **FAILED** : an error occurred while trying to execute the ``Action``.
|
||
|
|
- **DELETED** : the ``Action`` is still stored in the ``Watcher database``
|
||
|
|
but is not returned any more through the Watcher APIs.
|
||
|
|
- **CANCELLED** : the ``Action`` was in **PENDING** or **ONGOING** state and
|
||
|
|
was cancelled by the ``Administrator``
|
||
|
|
|
||
|
|
``Actions`` are created by ``Watcher Planner`` as result of Audit's execution.
|
||
|
|
``Action`` can't be created, modified or deleted by user.
