Gnocchi is an open-source, multi-tenant timeseries, metrics and resources database that is built on top of common OpenStack components. Initiated two years ago, Gnocchi has been undergoing intense performance testing and some shortcomings have been discovered. Poor distribution of tasks, degradation in performance of long series, and rigid typing hamper user experience. The good news is help is on the way!
This talk highlights the testing done against Gnocchi, the changes made to address issues, and how the results compare to previous versions. It will also provide some insights into how to deploy Gnocchi, specifically with Ceph, and why you should immediately start moving away from Ceilometer's legacy storage options.
