前提说明：在日常的项目中，由于数据量大，数据库隔几天就会自动宕机，独自运行的程序也会自行宕机，或者网络不稳当。产生的各种各样的问题，有时候没有及时发现会导致问题变得越来越大。于是写了一个监控系统，每隔1分钟对程序进行监测，如有离线状态的消息，每隔5分钟会发送邮件，方便正常维护处置。

1.Demo
2.建表
总共建两张表即可
CREATE TABLE `socket` (
`id` varchar(255) NOT NULL,
`mc` varchar(255) DEFAULT NULL,
`ip` varchar(255) DEFAULT NULL,
`prot` varchar(255) DEFAULT NULL,
`status` varchar(255) DEFAULT NULL,
`time` timestamp NULL DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP,
`ifsocket` int(11) DEFAULT NULL,
`ifdelte` int(11) DEFAULT NULL,
PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;CREATE TABLE `email` (
`id` int(11) NOT NULL AUTO_INCREMENT,
`email` varchar(255) DEFAULT NULL,
PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=3 DEFAULT CHARSET=utf8;3.后端代码
