監控cdn上的頁面訪問示例：

郵件腳本如下：

#!/usr/bin/python
#coding:utf-8
import smtplib
from email.mine.text import MIMEText
import sys
mail_host = 'stmp.163.com'
mail_user = 'test@163.com'
mail_pass = 'your_mail_password'
mail_postfix = '163.com'
def send_mail(to_list,subject,content):
me = "zabbix 監控告警平臺"+"<"+mail_user+"@"+mail_postfix+">"
msg = MIMEText(content,'plain','utf-8')
msg['Subject'] = subject
msg['From'] = me
msg['to'] = to_list
try:
s = smtplib:SMTP()
s.connect(mail_host)
s.login(mail_user,mail_pass)
s.sendmail(me,to_list,msg.as_string())
s.close()
return True
except Exception,e:
print str(e)
return False
if __name__ == "__main__"
send_mail(sys.argv[1], sys.argv[2], sys.argv[3])
