This exposes a Swift container's storage policy as a metadata attribute in Ceilometer samples (via the storage.containers.objects and storage.containers.objects.size meters) and the swift_account Gnocchi resources, named storage_policy. The storage policy determines the location and replication parameters for a Swift container, making it a useful metric for billing alongside the size of the container. The storage policy for a container cannot be changed unless the container is recreated, meaning that it does not change often (making it suitable to be stored in Gnocchi as a metadata attribute). The reason why this was not possible before was that Swift did not return the storage policy for each container in the GET account request, but a new proposed change to Swift [1] adds it to the response as the storage_policy attribute. This change for Ceilometer takes advantage of this and adds it to Ceilometer samples and the Gnocchi resource type. For this to work, the Swift change needs to be accepted and merged.

features:
|
|
- |
|
|
The ``storage_policy`` resource metadata attribute has been added to the
|
|
``swift.containers.objects`` and ``swift.containers.objects.size`` meters,
|
|
populated from already performed Swift account ``GET`` requests.
|
|
This functionality requires using a new version of Swift that adds the
|
|
``storage_policy`` attribute when listing containers in an account.
|
|
Ceilometer is backwards compatible with Swift versions that do not
|
|
provide this functionality, but ``storage_policy`` will be set to
|
|
``None`` in samples and Gnocchi resources.
|
|
- |
|
|
An optional ``storage_policy`` attribute has been added to the
|
|
``swift_account`` Gnocchi resource type, to store the storage policy for
|
|
Swift containers in Gnocchi. For Swift accounts, ``storage_policy`` will
|
|
be set to ``None``.
|
|
upgrade:
|
|
- |
|
|
To publish the ``storage_policy`` attribute for Swift containers,
|
|
``gnocchi_resources.yaml`` will need to be updated to the latest version.
|
|
Swift in the target OpenStack cloud will also need upgrading to add
|
|
support for providing the storage policy when listing containers.
