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 (http://en.wikipedia.org/wiki/Non-repudiation) This documentation has for objective to give you some clues on how to contribute code to ceilometer.
