python实现自动监控网站并发送邮件告警

通过定时执行python脚本,可以实现定期批量访问网站,如果发现网站打不开,第一时间发邮件到管理员邮箱进行预警

这里用的是python3.5

需要安装的插件:

smtplib:发邮件需要用到

pycurl:访问网站时会需要用到

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 sys

import smtplib

from email.mime.text import MIMEText

from email.mime.multipart import MIMEMultipart

class 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'] = '[e-mail]'

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 sys

import pycurl

class 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[e-mail]改成你自己的邮箱,

2、把文件路径改成自己的真实路径
