View cloud usage statistics
===========================

The Telemetry module provides user-level usage data for
OpenStack-based clouds, which can be used for customer billing, system
monitoring, or alerts. Data can be collected by notifications sent by
existing OpenStack components (for example, usage events emitted from
Compute) or by polling the infrastructure (for example, libvirt).

.. note::

   You can only view metering statistics on the dashboard (available
   only to administrators).
   The Telemetry service must be set up and administered through the
   :command:`ceilometer` command-line interface (CLI).

   For basic administration information, refer to the "Measure Cloud
   Resources" chapter in the `OpenStack End User Guide
   <http://docs.openstack.org/user-guide/>`_.
