Gnocchi – Metric as a Service
Why Gnocchi?
Gnocchi has been created to fulfill the need of a time series database usable in the context of cloud computing: providing the ability to store large quantities of metrics and being easily scalable.
The Gnocchi project was started in 2014 as a spin-off of the OpenStack Ceilometer project to address the performance issues that Ceilometer encountered while using standard databases as a storage backends for metrics. More information are available on Julien's blog post on Gnocchi.
