利用Python自动监控网站并发送邮件告警的方法

Python  /  管理员 发布于 7年前   237

前言

因为有一些网站需要每日检查是否有问题，所以需要一个报警监控的机制，这个需要你指定你发送的邮箱和你接收的邮箱，就可以做到对网站自动监控了。

这里用的是python3.5

需要安装的插件:

      1、smtplib:发邮件需要用到

      2、pycurl:访问网站时会需要用到

      3、linecache:在读取txt网站清单时需要用到

具体思路:

python程序从txt里面批量读取到网站的信息,通过Curl.py模拟浏览器去访问网站,并且把访问的结果写入到以自己的网站名称-日期.txt格式的文件中记录;有几种情况:

1、如果发现打不开了,直接发邮件提示网站已经打不开

2、发现可以打开,读取文件中上一次访问的情况(读取txt文件最后一行),

    1)如果发现上一次是打不开的,发邮件提醒网站已经恢复了

    2)如果发现上一次是打得开的(200的返回码),只是记录网站访问的日志就可以了

总共4个文件

Email.py是邮件类,主要用来发邮件的时候调用,这里需要按照你的情况改成你的邮箱(msg['From']),邮箱服务器地址(SMTP地址),和你的邮箱密码(SMTP.login)

Email.py

#!/usr/bin/python#-*- coding:utf-8 -*-import sysimport smtplibfrom email.mime.text import MIMETextfrom email.mime.multipart import MIMEMultipartclass Email_send(object): def __init__(self,msgTo,data2,Subject):  self.msgTo=msgTo  self.data2=data2  self.Subject=Subject def sendEmail(self):  # (attachment,html) = content  msg = MIMEMultipart()  msg['Subject'] = self.Subject  msg['From'] = '[email protected]'  msg['To'] = self.msgTo  html_att = MIMEText(self.data2, 'html', 'utf-8')  #att = MIMEText(attachment, 'plain', 'utf-8')  msg.attach(html_att)  #msg.attach(att)  try:   smtp = smtplib.SMTP()   smtp.connect('smtp.xxxx.com', 25)   smtp.login(msg['From'], 'xxxx') #改成自己的邮箱密码   smtp.sendmail(msg['From'], msg['To'].split(','), msg.as_string())   return('邮件发送成功')  except Exception as e:   print('--------------sss------',e) def curl(self):  import pycurl  c=pycurl.Curl()  #url="www.luoan.com.cn"  #indexfile=open(os.path.dirname(os.path.realpath(__file__))+"/content.txt","wb")  c.setopt(c.URL,url)  c.setopt(c.VERBOSE,1)  c.setopt(c.ENCODING,"gzip")  #模拟火狐浏览器  c.setopt(c.USERAGENT,"Mozilla/5.0 (Windows NT 6.1; rv:35.0) Gecko/20100101 Firefox/35.0")  return c

Curl.py 主要用来执行模拟浏览器访问网站并返回结果的文件

#!/usr/bin/python#-*- coding:utf-8 -*-import sysimport pycurlclass Curl(object): def __init__(self,url):  self.url=url def Curl_site(self):  c=pycurl.Curl()  #url="www.luoan.com.cn"  #indexfile=open(os.path.dirname(os.path.realpath(__file__))+"/content.txt","wb")  c.setopt(c.URL,self.url)  c.setopt(c.VERBOSE,1)  c.setopt(c.ENCODING,"gzip")  #模拟火狐浏览器  c.setopt(c.USERAGENT,"Mozilla/5.0 (Windows NT 6.1; rv:35.0) Gecko/20100101 Firefox/35.0")  return c

site_moniter.py 这个文件为主程序,主要执行调用上面的函数,读取txt文件中的网站清单,如果网站打不开就发邮件出来告警

需要注意:

      1、把[email protected]改成你自己的邮箱,

      2、把文件路径改成自己的真实路径
