Python's way of monitoring windows via Ssh-powershell

The examples in this article describe how Python monitors windows through Ssh-powershell. Share to everyone for your reference. The specific analysis is as follows:

For server monitoring, monitoring Linux Whether it's a do-it-yourself script or some open-source tool such as Nagios,zenoss or something. But after all, some companies have windows to do the server, relative to Linux, Windows is not convenient shell,cmd under the command for monitoring is far from Linux convenience. But now windows if installed PowerShell (win7,2008), more convenient than before, Linux commands are basically able to perform in the PowerShell, such as viewing the process or PS.

itself encapsulates a python via SSH (via Pexpect module) to invoke the PowerShell script, which packs fast ps,netstat,ping detection, viewing hard disk, CPU information and load, memory information. By creating the Ssh_win32 class object, and then calling its method, all of the returned objects are parse-good Python objects.
