Welcome to the Distil Documentation!

Project scope

Distil is a service to provide easy interactions with ERP systems, by exposing a configurable set of collection tools and transformers to make usable billing data out of Ceilometer entries.

Distil provides a rest api to integrate with arbitrary ERP systems, and returns quotations/invoices as json. What the ranges are, and how Ceilometer data is aggregated is intended to be configurable, and defined in the configuration file.

The Distil data store will prevent overlapping bills for a given tenant and resource ever being stored, while still allowing for regeneration of a given invoices.

Design principles

Distil, as with all OpenStack projects, is designed with the following guidelines in mind:

• Component-based architecture. Quickly add new behaviors
• Highly available and scalable. Scale to very serious workloads
• Fault tolerant. Isolated processes avoid cascading failures
• Recoverable. Failures should be easy to diagnose, debug, and rectify
• Open standards. Be a reference implementation for a community-driven
