实现真实的机柜模拟图[原创]

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。
在线效果图
http://blog.liuts.com/idc/
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

怎么实现自动检测宕机呢？

与nagios结合。

我在安装编译时也是提示/home/liuts/xxxxx 这个错误。

感谢分享！
按README编译时总提示/home/liuts/xxxxx，然后看了一下有太多地方有这个了，没有一个配置文件可以更改的吗？

编译出servermap后不能用./servermap 运行？

请帮助，谢谢

刘天斯回复于 2010/12/01 11:14

ServerMap1.1版已经修复。

咦我怎么看把HTML代码封装到了C++里面了。为啥不把UI的东西拿出来呢？现在不是提倡所谓MVC分层设计理念嘛。

刘天斯回复于 2010/07/24 14:09

仁兄说得很有道理，由于是一个小项目所以我都放在一块处理了。
