CloudKitty is a rating component for OpenStack developed by Objectif Libre to provide metering and charging capabilities. It collects usage data from Ceilometer, applies configurable rating policies to transform the data, and stores the results. CloudKitty's modular architecture allows it to interface with different data sources and billing backends. It provides dashboards and reports to help users track resource usage and costs. Objectif Libre offers CloudKitty as part of its OpenStack consulting and support services.

Allows importing into third-party software

17. A closer look at Hashmap
Matching arbitrary values from service type to
resource metadata
 Group : Define set of rules that are processed together
 Service : Match a CK Service (compute, network,..)
 Field : Match a resource metadata field (flavor,
image_id,...)
 Mapping
- Can be attached to a service or a field
- Map the value of a metadata to a cost and a type of cost
 Threshold
- Can be attached to a service or a field
- Define thresold levels on a metadata to a cost and a type of cost

18. Enough chalk talk !
Let's create a rating policy
and look at the impact on the user side
