Dear bug triager. This bug was created since a commit was marked with DOCIMPACT.
Your project "openstack/watcher" is set up so that we directly report the documentation bugs against it. If this needs changing, the docimpact-group option needs to be added for the project. You can ask the OpenStack infra team (#openstack-infra on freenode) for help if you need to.

    Add a generic and extensible way to describe the flow of actions

    In watcher, an audit generates a set of actions which
    aims at achieving a given goal (lower energy consumption, ...).
    It is possible to configure different strategies in order to achieve
    each goal. Each strategy is written as a Python class which produces
    a set of actions. Today, the set of possible actions is fixed for a
    given version of Watcher and enables optimization algorithms to
    include actions such as instance migration, changing hypervisor state,
    changing power state (ACPI level, ...).

    This patchset propose a generic and extensible way to describe
    the actions and his parameters that we want to add to Action Plan.
    It also remove the static actions because they are now deprecated.

    The documentation regarding strategy plugin need to be
    updated (plugins.rst).

    Updated Strategy plugin doc

    As we modified the way a strategy gets implemented in
    blueprint watcher-add-actions-via-conf, this patchset updates the
    documentation regarding the implementation of a strategy plugin.

    Doc on how to set up a thirdparty project

    This documentation is a pre-requisite to all plugin documentation
    as it guides you through the creation of a project from scratch
    instead of simply forcusing on the implementation of the plugin
    itself.
