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

zabbix.writeToXls()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：
