Installing OpenStack Telemetry
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.
Getting ready
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 controller and 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 controller and 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
How to do it...
To enable the Telemetry (ceilometer) service, first carry out the following steps on the controller node:
- Ceilometer requires...
