python 监控 api 脚本

xiaoyu28

这个脚本的作用是: 访问 url,返回码大于500就发送报警邮件

主要用了 requests 模块, 所以跑监控脚本的 机器要先安装 requests
pip install requests

• #!/usr/bin/env python
  
  
• # -*- coding: utf-8 -*-
  
• 
  
• import smtplib
  from email.mime.text import MIMEText
  import sys
  
• import requests
  
• 
  
• 
  
• urls=[]
  
• urls.append('http://www.abc.cn/v1/users.json')
  
• urls.append('http://www.abc.cn')
  
• 
  
• 
  
• # 报警邮件参数设置, 前三行是用来发件的邮箱的配置
  
• mail_host = 'smtp.exmail.qq.com'
  
• mail_user = 'xj@abc.cn' #qq邮箱这个地方必须写全！
  
• mail_pass = "123456"
  
• mail_postfix = 'suibianxie.com'
  
• admin_email = 'admin@youremail.com'
  
• 
  
• 
  
• 
  
• 
  
• # 邮件发送函数
  
• def send_mail(to_list,subject,content):
  
•     me = mail_user+""
  
•     msg = MIMEText(content)
  
•     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
  
• 
  
• 
  
• # 主体部分
  
• for url in urls:
  
•     try:
  
•         r = requests.get(url,timeout=3)
  
•         if r.status_code >= 500:
  
•             msg = 'Error: ' + str(r.status_code) + ' ' + url
  
•             print "send email"
  
•             send_mail( admin_email,"api error",msg)
  
•             print "done"
  
•     except requests.exceptions.ConnectionError as e:
  
•         print "These aren't the domains we're looking for."
  
•     except requests.exceptions.ConnectTimeout as e:
  
•         print "Too slow Mojo!"
  
•     except requests.exceptions.HTTPError as e:
  
•         print "And you get an HTTPError:", e.message
  

之后放 crontab 里面运行就行
