Feature: Provide support for auditing events in standardized formats in Ceilometer and add support in oslo so that every OpenStack component can use it. Reason: Ceilometer is a reliable, core centralized service with the ability to track usage information towards statistical usage analysis and billing. Many of the projects are seeing similar “auditing” requirements but now with the emphasis on tracking access to services (by users and other services) for the purposes of security auditing. The support in Oslo provides the ability for any OpenStack service to audit usage information. Result: Leverage the design (agents/meters, etc.) and logging facilities already in Ceilometer and enable users to configure additional meters to allow event data to be produced in one or more (standard) formats. The configuration may also provide the location as to where the logs are created for each meter type.
