Ceilometer是OpenStack中的一个子项目，它像一个漏斗一样，能把OpenStack内部发生的几乎所有的事件都收集起来，然后为计费和监控以及其它服务提供数据支撑。Ceilometer的核心架构图如下：

At present, most of the Nova meters will
only work with libvirt front-end hypervisors while test coverage was mostly
done based on KVM. Contributors are welcome to implement other virtualization
backends’ meters or complete the existing ones.
