一般能反映機房設備位置、結構我們都喜歡通過網絡拓撲圖來展現，但個人感覺還不夠直觀、明了的表現出自己想要的結果(自己太挑剔了，呵呵)。因此寫一個生成真實機柜模擬圖平臺，實現與真實服務器外觀、服務狀態、空閑位置等信息。
在線效果圖
http://blog.liuts.com/idc/
系統截圖
1、平臺顯示某一排截圖
2、平臺顯示某臺服務器詳細信息截圖
3、狀態說明
2U服務器正常狀態
2U服務器當機狀態
系統原理
通過獲取運維平臺的服務器信息(包括位置、操作系統、機型等)，格式為XML，通過c++的tinyxml來解析并渲染成比較美觀的HTML格式。當機的信息通過Nagios來獲取。這樣就可以生成非常人性化的展現平臺了：）
系統代碼Servermap.cpp
