Icehouse Design Summit

This session will include the following subject(s):

PaaS Event Usage Collection:

Ceilometer must be able to efficiently extract and process usage information from services in order to properly generate bills. In order to be able to efficiently process usage data, ceilometer requires services to implement a consistent interface. This document describes the metering requirements, use cases and provides a architecture for collection of usage information from Platform as a Service (PaaS) offerings.

(Session proposed by Phil Neal)

PaaS Event Format for Ceilometer Collection :

Up until recently the focus of OpenStack has been on infrastructure level services (compute, storage, networking), but there are a large number of PaaS services that are currently in development and also a growing number of applications running on OpenStack systems. Many of these new applications will need to be metered for a variety of reasons: internal systems management, license management, end customer billing. Ceilometer currently supports collection of metering information for infrastructure level services. The general mechanism has been to either create a targeted agent or use the existing service APIs to meter these systems. While this approach has worked for the existing set of services, it will run into a several problems as the number of PaaS and SaaS services that need to be metered expand. The main issue is that it will not be viable to do custom integrations for the potentially hundreds (and eventually thousands) of services that may be hosted in OpenStack. This blueprint provides a proposal for standardizing the format of integrations so that Ceilometer can consume metering data from any conforming application without doing any custom integration or even a code change.
