Telemetry and charging back
OpenStack provides telemetry for tenant environments with the Ceilometer service. The Ceilometer project aims to support cloud operators to collect metrics, further assisting and understanding resource utilization. This enables us to address infrastructure scalability issues and update resource planning for expansion and growth before hitting the resource limits. Since the Queens OpenStack release, the telemetry module has been extended with additional components that work in tandem with Ceilometer, including the following:
- Aodh: An alarming service that acts upon collected metrics data
- Gnocchi: A data store and collection of time series data
- Panko: A data store for events data generated by Ceilometer
Important note
At the time of writing this edition, the Panko module has been deprecated and is no longer maintained by the OpenStack community.
The next section will highlight the telemetry stack in more detail.
