Python's approach to monitoring windows through 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 either by itself or with some open source tools such as Nagios,zenoss or whatever. But after all, some companies have Windows do server, compared to Linux, Windows does not have the convenience of SHELL,CMD commands for monitoring is far from Linux convenience. But now if you install PowerShell (win7,2008) on Windows, it's much more convenient than before, and the commands on Linux can be executed in PowerShell, such as viewing a process or PS.

It encapsulates a python script that invokes PowerShell via SSH (via the Pexpect module), inside the packet fast ps,netstat,ping detection, view hard disk, CPU information and load, memory information. By creating a Ssh_win32 class object and then calling its method, the parsed Python object is returned.
