python为运维人员打造一个监控脚本

0x00前言：

一直想写一个监控方面的脚本，然后想到了运维这方面的

后来就写了个脚本。

0x001准备：

psutil模块

0x02正文：

import os
import time
import re
import smtplib
from email.mime.text import MIMEText
from email.header import Header
import socket
import psutil
while True:
  def jianca():
      print('[+]Write a port to a file')
      querys=os.popen('netstat  -an').read()
      wsd=open('netstat.txt','w')
      wsd.write(querys)
      wsd.close()
  jianca()
 
  def swsd():
      global usd,ow
      wsd=open('netstat.txt','r')
      swd=wsd.read()
      odf=re.findall('(25[0-5]|2[0-4]\d|[0-1]\d{2}|[1-9]?\d)\.(25[0-5]|2[0-4]\d|[0-1]\d{2}|[1-9]?\d)\.(25[0-5]|2[0-4]\d|[0-1]\d{2}|[1-9]?\d)\.(25[0-5]|2[0-4]\d|[0-1]\d{2}|[1-9]?\d):(3389)',swd)
      usd=odf[0]
      print('[+]Query the IP address of a remote connection')
      df=usd[0],usd[1],usd[1],usd[3]
      wdst=".".join(df)
      ow=wdst+":"+usd[4]

      s=socket.socket(socket.AF_INET,socket.SOCK_DGRAM)
      dw=s.connect(('8.8.8.8',80))
      ip=s.getsockname()[0]
      print('[+]loacl IP:',ip)
      wdf=os.popen('tasklist').read()
      timsd=time.strftime('%Y-%m-%d',time.localtime(time.time()))
  ipdw()

             '[+]Disk I/O usage{}\n' \
             '[+]Last send time:{}\n' .format(ow,ip,wdf,cput,cp,timsd)
      msg=MIMEText(zhengwen)
      msg['From']=Header('你的搜狐邮箱@sina.cn')
      msg['TO']=Header('收件箱@qq.com','utf-8')
      sub="实时监控"
      msg['subject']=Header(sub,'utf-8')
      try:
          smtp=smtplib.SMTP()
          smtp.connect('smtp.sina.cn',25)
          smtp.login('搜狐邮箱@sina.cn','登录密码')
          smtp.sendmail(serder,revw,msg.as_string())
          print('[+]发送出')
      except Exception as g:
          print('[-]发送失败，原因:',g)
  stm()
 
  time.sleep(3600)

　　实现原理：首先获取端口状态，然后写人一个txt用正则提取出想要的IP和端口。

然后获取正在后台运行的程序。在获取CPU和磁盘I/O的内存，然后通过邮箱发送‘

到指定收件箱。
