基于Python脚本实现邮件报警功能

使用了smtplib等第三方库,进行发送邮件,完成邮件报警功能

如下是实例 :

#!/usr/bin/python

import glob
import operator
from optparse import OptionParser
import smtplib
import email.MIMEText as MIMEText
import email.Utils.formadate as formatdate

msg = ""
#主方法
def main():
 global options
 global msg

parser = OptionParser(add_help_option=False)
 parser.add_option("-m", "--mail", dest="mail", type="str", help="email address to send report result (comma separated)")
 parser.add_option("-t", "--title", dest="title", type="str", help="email title (default:Error File Count)")
 parser.add_option("-a", "--admin", dest="admin", type="str", help="set sender address. works with -m option")
 (options, args) = parser.parse_args()

#这里监控文件夹下的文件数,超出25个文件即报警
 datanum = cntFiles("/data/","csv")
 if (operator.gt(datanum,25)):
   msg += " Please be alert : \n the number of files under /data/ path is greater than 25 :"
   msg += "\n =========================================="
   msg += "\n The number of files is : " + str(datanum)
   sendmsg(options,msg)
 print("==== end ====")

#添加发送邮件的信息
def sendmsg(options,msg):
 if options.mail:
   toAddr = options.mail
   if options.admin:
     fromAddr = options.admin
   else:
     fromAddr = 'zhangsan@neiyou.cn'#这里是公司的公用SMTP邮箱账号

if options.title:
     subject = options.title
   else:
     subject = 'File Stacking Alarm'
   msg += "\n ========================================== \n"
   print( msg)
   msg = createMsg(fromAddr, toAddr, subject, msg)
   print( msg)
   send(fromAddr, toAddr, msg)
 else:
   print( msg)

#glob方法,统计文件夹下的文件数
def cntFiles(in_directory, ext):
 stage = len(glob.glob1(in_directory,"*." + ext))
 return stage

#创建邮件头
def createMsg(fromAddr, toAddr, subject, body):
 msg = MIMEText(body)
 msg['Subject'] = subject
 msg['To'] = toAddr
 msg['From'] = fromAddr
 msg['Date'] = formatdate()
 return msg

#发送邮件
def send(fromAddr, toAddr, msg):
 try:
   #这里添加公司的SMTP邮箱地址
    s = smtplib.SMTP('192.168.12.120')
    s.sendmail(fromAddr, toAddr.split(','), msg.as_string())
    s.close()
    print("SUCCESS: sending email")
 except smtplib.SMTPException:
    print("ERROR: sending email")

if __name__ == '__main__':
 main()

linux上做计划任务,把指令添加进计划任务中:

Errymsfileemail.py -m zhangsan@gongsi.cn -t "[ERROR/$HOST] File Stacking Alarm"
