How to monitor windows using ssh-powershell in python

This example describes how to monitor windows using ssh-powershell in python. Share it with you for your reference. The specific analysis is as follows:

For server monitoring, whether it is writing scripts by yourself or using some open-source tools such as nagios and zenoss in linux. However, some companies still use windows as servers. Compared with linux, windows does not have a convenient shell. commands provided by cmd are far from linux convenience for monitoring. However, if powershell (win7, 2008) is installed on windows, it is much more convenient than before. linux commands can basically be executed in powershell, such as viewing the process or ps.

I encapsulated a python script that calls powershell through ssh (through the pexpect module), which includes ps, netstat, ping detection, and viewing hard disk, cpu information, load, and memory information. By creating an ssh_win32 Class Object and calling its method, the returned python objects are parsed.
