The Ceilometer project aims to deliver a unique point of contact for billing systems to acquire all of the measurements they need to establish customer billing, across all current OpenStack core components with work underway to support future OpenStack components.
What is the purpose of the project and vision for it? Provide efficient collection of metering data, in terms of CPU and network costs. Allow deployers to integrate with the metering system directly or by replacing components. Data may be collected by monitoring notifications sent from existing services or by polling the infrastructure. Allow deployers to configure the type of data collected to meet their operating requirements. The data collected by the metering system is made visible to some users through a REST API. The metering messages are signed and non-repudiable.
