Rethinking Ceilometer metric storage with Gnocchi: Time-series as a Service

Sign up or log in to save this to your schedule and see who's attending!



When we started Ceilometer, we designed our metrics storage in a way that looked more like audit system that traditional metering tool.

Recent evolution in OpenStack and Ceilometer pushed us to rethink how we should treat and store metrics. This led to the creation of the Gnocchi project, a service providing time-series indexing and storage via an API, following the OpenStack philosophy.

This talk will explain the design ideas underpinning Gnocchi, how it differs from the classic metering store provided by Ceilometer, and how it has been integrated into the Ceilometer metrics pipeline. We will also discuss the potential for performance & scalability improvements, and how the new metrics store will co-exist with the existing v2 Ceilometer API.
