利用python 监控告警 nginx，mysql 进程

这个是进程nginx的，大家可以修改下里面的 ps -C 进程名

#!/usr/bin/env python
import os, sys, time
while True:
    time.sleep(3)
    try:
ret = os.popen('ps -C nginx -o pid,cmd').readlines()
        if len(ret) <2:
            print "nginx process killed, restarting service in 3 seconds."
            time.sleep(3)
            os.system("service nginx restart")
    except:
        print "Error", sys.exc_info()[1]

邮件的可以用话smtplib发送

#!/usr/bin/python
# -*- coding: utf-8 -*-
