一般能反映机房设备位置、结构我们都喜欢通过网络拓扑图来展现，但个人感觉还不够直观、明了的表现出自己想要的结果(自己太挑剔了，呵呵)。因此写一个生成真实机柜模拟图平台，实现与真实服务器外观、服务状态、空闲位置等信息。

系统截图
1、平台显示某一排截图

2、平台显示某台服务器详细信息截图

3、状态说明
2U服务器正常状态

2U服务器当机状态

系统原理
通过获取运维平台的服务器信息(包括位置、操作系统、机型等)，格式为XML，通过c++的tinyxml来解析并渲染成比较美观的HTML格式。当机的信息通过Nagios来获取。这样就可以生成非常人性化的展现平台了：）

系统代码Servermap.cpp
