思路：
利用python的pyzabbix模块去连接Zabbix API，先判断主机是否存在，存在的话就获取这个主机的item，然后在Zabbix API中的history.get中的方法获取这些item是否有数据，有的话就是获取这些数据，然后在这个获取这个主机对应的的绘图，绘图对应的item，判断一个绘图里面有数据的item大于一，然后获取这些绘图加入到screen
软件包pyzabbix
pip install pyzabbix

-G：生成新的screen
-H：zabbix定义的主机名
-c：指定需要几列
例子：
./screen_graph.py -G tom -H 10.0.100.3 -c 2
注：对于数据量大的主机生成screen会有点慢
