Instructions for using python to run nmon

Instructions for using python to run nmon

Step one:

Installation: paramiko

Window installation method: pip install paramiko

Reference: http://www.jb51.net/article/97655.htm

Step 2:

The following code contains sending commands and downloading all files under a single file and directory file

The disadvantage is that it does not write out the multi-process mode of execution.

# coding=utf-8

Import paramiko,time,threading

Import os, sys,shutil

From stat import *

Def get_year_mon_day_hour_min_sec ():

Time_array = time.localtime ()

Result= "% s:%s:%s:%s:%s:%s"% (time_array.tm_year,time_array.tm_mon,time_array.tm_mday,time_array.tm_hour,time_array.tm_min,time_array.tm_sec)

Return result

Def get_year_mon_day ():

Time_array = time.localtime ()

Result= u "% s year% s% s day"% (time_array.tm_year,time_array.tm_mon,time_array.tm_mday)

Return result

Def get_hour_min_sec ():

Time_array = time.localtime ()

Result= u "% s:% s"% (time_array.tm_hour,time_array.tm_min,time_array.tm_sec)

Return result

Def get_y_m_d_h_ms ():

Import datetime

Result = datetime.datetime.now () .strftime ("% Y% m% d% H% M% S _")

Return result

Supplementary explanation

The user name needs to have executable permission, otherwise it fails.
