The OpenStack Telemetry project, also called Ceilometer, provides you with the ability to collect metering data of the physical and virtual resources comprising deployed OpenStack components and persist this data for subsequent retrieval and analysis. It can also trigger actions when the defined criteria are met.
Ensure you have suitable servers running the OpenStack components. If you are using the accompanying Vagrant environment, as described in the Preface, we will use the same
compute-01 nodes for this recipe.
We will be installing Ceilometer packages on a
controller node and a
compute node. Ensure you are logged into the
compute-01 nodes in our environment. If you created these nodes with Vagrant, you can execute the following command:
vagrant ssh controller vagrant ssh compute-01
