Python+Mysql生成zabbix统计数据-原创手记-慕课网

先大概了解一下zabbix数据库结构：

1、groups表

可以根据组名查到组ID

2、找到组ID就可以根据组ID找出这个组下面的所有服务器的ID，这个关系在hosts_groups表里面：

3、有了hostid就可以在hosts表里查看这台机器的基本信息了：

items表则可以根据hostid查出这台服务器的所有监控项：

4、终于在items表查到itemid，利用这个itemid在trends和trends_uint这两个表中统计出我们需要的数据

我python水平挺菜的，很多面向对象的功能都不知道咋用，求大神教育

生成xls文件我用了一个叫xlsxwriter的第三方库，这个库只能写不能读，感觉还可以，生成出来的效果：
