Open Stack

We exuberantly announce the release of:

python-watcher 1.10.0: OpenStack Watcher provides a flexible and
scalable resource optimization service for multi-tenant OpenStack-
based clouds.

This release is part of the rocky release series.

The source is available from:

    https://github.com/openstack/watcher

Download the package from:

    https://tarballs.openstack.org/watcher/

Please report issues through launchpad:

    https://bugs.launchpad.net/watcher

For more details, please see below.

1.10.0
^^^^^^

New Features

* Feature to exclude instances from audit scope based on project_id
  is added. Now instances from particular project in OpenStack can be
  excluded from audit defining scope in audit templates.

* Added a strategy for one compute node maintenance, without having
  the user's application been interrupted. If given one backup node,
  the strategy will firstly migrate all instances from the maintenance
  node to the backup node. If the backup node is not provided, it will
  migrate all instances, relying on nova-scheduler.
