简述：这个工具能够通过监控得到database和host的近期一个月，3个月，一年和全部时间的内的可用率（默认在未监控时，database和host是可用的。没实用uptime/uptime+downtime的方式计算），并且还能够看到database和host在被监控到的时期的在线和离线时间。

这样能够了解database和host各个时期的使用情况。

使用环境： ???? 能够监控mysql服务和server的可用率和离线时间用法：本工具是通过把配置监控信息写入的监控配置中心。然后实时分析採集的数据。能够把这个工具部署到服务端，通过并发批量检查大量的database和host

安装方法：本工具是用python开发并已经打包，能够直接下载使用。没有环境依赖

特别说明： 1. interval參数特别重要，为了提高可用率的准确率。这个间隔时间的选取必须和本工具被调用时间间隔一样。配置中心的数据库脚本
