最近发现一篇文章《使用zabbix api创建screen》，然后下载脚本进行测式，发现二个问题：
1. 不支持3.x版本。
2. 添加的screen的主机名称不是按顺序排列，不方便查询。
便自己修改了一下，让支持zabbix3.x版本，并输出的screen(聚合图形)按机器名称排列。

使用方法：
python create_screen.py -g hadoop -G ‘Network traffic on bond0‘ -c 4 -n ‘Hadoop bond0‘
-g 要显示zabbix的群组。
-G 要显示的zabbix图形。
-c 显示几列，注意要调整脚本里的：‘width‘: ，‘height‘: 参数来设置大小。
-n 在screen 里面显示的名称。
上面的命令的意思就是：把haddop组里面每个服务器的Network traffic on bond0图形，接每列4个图形的显示在Haddop bond0的screen里。
