Ceilometer is an OpenStack incubated project which started in April 2012 with the goal to provide a unique interface point to provide measurement in OpenStack. Our purpose for measurement started with a focus on metering (for billing) and has since been extended to other targets such as monitoring and alerting. This project is a collaboration of a wide variety of actors.

After a brief introduction of the project past and future, this talk will introduce the audience to the project's architecture before digging into how and why they can contribute to its future.
