通过抓取pintpoint2的页面信息把数据存入数据库python3

目标：对生产环境的服务质量进行量化，

解决办法：把pintpoint2里的数据转存入mysql数据库，作成报表，目前支持总请求数，错误请求数，中位数，平均数，95值（每分钟一次定时任务），其它指标可以根据要求进行增加。

数据库建库语句：

CREATE TABLE `time_analysis` (
`id` int(10) unsigned NOT NULL AUTO_INCREMENT,
`datetime` datetime DEFAULT NULL COMMENT '时间',
`application_name` varchar(32) DEFAULT NULL COMMENT '应用名',
`totalcount` int(8) DEFAULT NULL COMMENT '总请求数',
`errorcount` int(8) DEFAULT NULL COMMENT '错误请求数',
`median` int(5) DEFAULT NULL COMMENT '中位数',
`average` int(5) DEFAULT NULL COMMENT '平均数',
`distribution95` int(5) DEFAULT NULL COMMENT '95值',
PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=358 DEFAULT CHARSET=utf8mb4 COMMENT='数据分析结果存署表';

CREATE TABLE `application_list` (
`application_name` varchar(32) NOT NULL,
`service_type` varchar(32) DEFAULT NULL COMMENT '服务类型',
`code` int(11) DEFAULT NULL COMMENT '服务类型代码',
`agents` int(11) DEFAULT NULL COMMENT 'agent个数',
`agentlists` varchar(256) DEFAULT NULL COMMENT 'agent list',
`update_time` datetime DEFAULT NULL ON UPDATE CURRENT_TIMESTAMP COMMENT '更新时间',
PRIMARY KEY (`application_name`),
UNIQUE KEY `Unique_App` (`application_name`) USING BTREE
) ENGINE=InnoDB DEFAULT CHARSET=utf8 COMMENT='pinpoint app list';
