.. _verify:
Verify operation
~~~~~~~~~~~~~~~~
Verify operation of the Telemetry service. These steps only include the
Image service meters to reduce clutter. Environments with ceilometer
integration for additional services contain more meters.
.. note::
Perform these steps on the controller node.
.. note::
The following uses Gnocchi to verify data. Alternatively, data can be
published to a file backend temporarily by using a ``file://`` publisher.
#. Source the ``admin`` credentials to gain access to
admin-only CLI commands:
.. code-block:: console
$ . admin-openrc
#. List available resource and its metrics:
.. code-block:: console
$ gnocchi resource list --type image
