单独代理

Agent是轻量级代理服务程序，被部署在单独代理服务器上，用于接收Server的数据采集需求，并为Server提供采集数据。

Agent is a lightweight proxy service program and is deployed on separate proxy server to receive data collection needs of the server and provide collected data .

更好地利用资源；无需对每个虚拟应用程序进行单独的代理和缓存。

Resources are better utilized ; there is no need to have separate proxy and caching for each virtual application deployment .

这个方法不仅让我们无需单独生成服务代理，而且服务和服务消费者的实现都可以使用同样的服务接口。

The usage of this approach not only allows us to bypass service proxy generation , but also to use the same interfaces for both service and client implementation .

此设置的缺陷在于，在总体数据中，不能单独使用来自每个代理的统计数据。

The drawback of this setting is that the statistical data from each agent that contributes to the total is not available .
