The option 'use_all_resource_revisions' is useful when using Gnocchi
with the patch introduced in [1]. That patch can cause queries to
return more than one entry per granularity (timespan), according to
the revisions a resource has. This can be problematic when using the
'mutate' option of Cloudkitty. Therefore, this option
('use_all_resource_revisions') allows operators to discard all
datapoints returned from Gnocchi, but the last one in the granularity
that is queried by CloudKitty. The default behavior is maintained,
which means, CloudKitty always uses all the data points returned.
However, when the 'mutate' option is not used, we need to sum all the
quantities and use this value with the latest version of the attributes
received. Otherwise, we will miss the complete accounting for the time
frame where the revision happened.

CloudKitty
Rating as a Service component
Goal
CloudKitty aims at filling the gap between metrics collection systems like ceilometer and a billing system.
Every metrics are collected, aggregated and processed through different rating modules. You can then query CloudKitty's storage to retrieve processed data and easily generate reports.
Most parts of CloudKitty are modular so you can easily extend the base code to address your particular use case.
You can find more information on its architecture in the documentation, architecture section.
Status
CloudKitty has been successfully deployed in production on different OpenStack systems.
You can find the latest documentation on readthedocs.
Contributing
We are welcoming new contributors, if you've got new ideas, suggestions or want to contribute contact us.
You can reach us thought IRC (#cloudkitty @ oftc.net), or on the official OpenStack mailing list openstack-discuss@lists.openstack.org.
A storyboard is available if you need to report bugs.
Additional components
We're providing an OpenStack dashboard (Horizon) integration, you can find the files in the cloudkitty-dashboard repository.
A CLI is available too in the python-cloudkittyclient repository.
Trying it
CloudKitty can be deployed with devstack, more information can be found in the devstack section of the documentation.
Deploying it in production
CloudKitty can be deployed in production on OpenStack Kilo environments, for more information check the installation section of the documentation. Due to oslo libraries new namespace backward compatibility is not possible. If you want to install it on an older system, use a virtualenv.
Getting release notes
Release notes can be found in the release notes section of the documentation.
