十一、安装计量服务（Telemetry service）：ceilometer
11.1主要功能：
##有效收集OPENSTACK服务相关的计量数据
##通过监控服务发送的通知收集事件和计量数据
##发布收集的数据到多种目标包括数据存储和消息队列
##当收集的数据触发定义的规则时创建警报。
11.2主要组件：
A compute agent (ceilometer-agent-compute)：计算代理，运行于各个计算节点并统计资源利用情况。
A central agent (ceilometer-agent-central)：中心代理，运行于中心管理服务器，收集统计与实例或计算节点无关的资源利用情况。
A notification agent (ceilometer-agent-notification)：通知代理，运行于中心管理服务器，根据消息队列中信息产生事件和计量数据。
A collector (ceilometer-collector)：收集器，运行于中心管理服务器，调度收集计量数据存储或未修改的外部用户
An alarm evaluator (ceilometer-alarm-evaluator)：警报器，运行于一个或多个中心管理服务器，用于确定当超过阈值时产生警报的间隔。
An alarm notifier (ceilometer-alarm-notifier)：通知器，运行于一个或多个中心管理服务器，为一堆以阈值为基础的模板设置告警。
An API server (ceilometer-api)：API服务，运行于一个或多个中心管理服务器，提供对存储的计量数据的访问。
##这些组件使用消息总线联系，只有收集器和API服务使用数据存储。
