linux定时监控网络连接，利用python发送邮件

服务器A需要调用服务器B上面的服务，但是经常遇到连接超时的问题，需要监控一下网络状态：

shell脚本：

#!/bin/sh

PYTHON_PATH=/usr/bin

ping -c 5 www.suiyuan521.com

if [ "$?" != "0" ]; then

$PYTHON_PATH/python send_email.py "I can not connect to abc.com"

fi

python发送邮件脚本：

# !/usr/bin/python

"""just a send email python script"""

#-*- coding: utf8 -*-

from email.MIMEMultipart import MIMEMultipart

from email.MIMEText import MIMEText

from email.Header import Header

from email.MIMEImage import MIMEImage

import smtplib

import sys

import datetime

import mimetypes

import os

"""send_email function"""

def send_email(subject, body):

sender = 'suiyuan@521.com'

file_name = './abc.txt'

msgRoot = MIMEMultipart()

msgRoot["Accept-Charset"] = "UTF-8"

msgRoot["Accept-Language"] = "zh-CN"

msgRoot['Subject'] = Header(subject,"UTF-8")

msgRoot['From'] = sender

receivers = ['suiyuan521@love.com']

msgRoot['To'] = ','.join(receivers)

msgRoot.preamble = '%s is a MIME message' % (subject)

msgAlternative = MIMEMultipart("alternative")

msgRoot.attach(msgAlternative)

if not body:

body = "随缘吧APP不错，给你带来缘分"

msgText = MIMEText(body)

msgText.set_charset("UTF-8")

msgText = MIMEText(body, 'html', 'UTF-8')

msgText.set_charset("UTF-8")

msgAlternative.attach(msgText)

// 发送附件

ctype,encoding = mimetypes.guess_type(file_name)

if ctype is None or encoding is not None:

ctype='application/octet-stream'

maintype,subtype = ctype.split('/',1)

file_msg=MIMEImage(open(file_name,'rb').read(),subtype)

basename = os.path.basename(file_name)

file_msg.add_header('Content-Disposition','attachment', filename = basename)

msgAlternative.attach(file_msg)

s = smtplib.SMTP('proxy-in.suiyuan.com') // 设置邮件服务器地址

s.sendmail(sender, receivers, msgRoot.as_string())

s.quit()

"""main function"""

if __name__ == '__main__':

body = sys.argv[1]

now_time = datetime.datetime.now()

yes_time = now_time + datetime.timedelta(days=-1)

yes_time_nyr = yes_time.strftime('%Y-%m-%d')

subject = "随缘吧助您监控网络状态"

send_email(subject,body)

然后将shell脚本加入crontab定时任务就可以了。
