Volume
^^^^^^
These metrics are emitted per volume node.
* ``openstack.cinder.volume_creation_time``, the time (in seconds) it took to create a new volume.
.. note:: When using Ceph as the backend storage for volumes, the ``hostname`` value is always set to ``rbd``.
These metrics are retrieved from the Cinder API.
* ``openstack.cinder.volumes.<state>``, the number of volumes by state.
