对于服务器的监控来说，监控linux不管是自己动手写脚本还是用一些开源的工具比如nagios，zenoss什么的。但毕竟还是有些公司有 windows做服务器的，相对linux来说，windows没有方便的shell，cmd下提供的命令对于监控来说远远没有linux方便。但是现在 windows上如果安装了powershell（win7，2008自带），就比以前方便多了，linux上的命令基本都能在powershell里执 行，比如查看进程还是ps.
自己封装了一个python通过ssh（通过pexpect模块）调用powershell的脚本，里面包 快ps，netstat，ping检测，查看硬盘，cpu信息和负载，内存信息。通过创建ssh_win32类对象，然后调用它的方法，返回的都是解析好 的python对象。
