之前部署了Zabbix（3.4.4版本）监控环境，由于主机比较多，分的主机组也比较多，添加聚合图形比较麻烦，故采用python脚本进行批量添加聚合图形。脚本下载地址：https://pan.baidu.com/s/1bpApIPp （密码：wpts）脚本操作如下：
[root@zabbix01 ~]# cd /opt/
[root@zabbix01 opt]# ls
create_Disk_space_usage_screen.py  create_screen.py

上面两个脚本create_screen.py和create_Disk_space_usage_screen.py，脚本中只需要按照自己的实际zabbix访问情况修改三处：
url
username
password

前者用于批量生成负载、带宽、IO等监控的聚合图形，后者用于生成磁盘监控的聚合图形。
两个脚本唯一不同的就是width和height的值不一样。


批量生成聚合图形的操作如下：
[root@zabbix01 opt]# python create_screen.py  -g '财务系统'  -G 'Network traffic on bond0' -c 2 -n '财务系统---Network traffic on bond0'
[root@zabbix01 opt]# python create_screen.py  -g '财务系统'  -G 'CPU load' -c 2 -n '财务系统---CPU load'
[root@zabbix01 opt]# python create_screen.py  -g '财务系统'  -G 'CPU utilization' -c 2 -n '财务系统---CPU utilization'
[root@zabbix01 opt]# python create_screen.py  -g '财务系统'  -G 'Memory usage' -c 2 -n '财务系统---Memory usage'
[root@zabbix01 opt]# python create_screen.py  -g '财务系统'  -G 'Read and Write speed on /' -c 2 -n '财务系统---Read and Write speed on /'
[root@zabbix01 opt]# python create_screen.py  -g '财务系统'  -G 'Read and Write speed on /data' -c 2 -n '财务系统---Read and Write speed on /data'
[root@zabbix01 opt]# python create_Disk_space_usage_screen.py  -g '财务系统'  -G 'Disk space usage /' -c 3 -n '财务系统---Disk space usage /'
[root@zabbix01 opt]# python create_Disk_space_usage_screen.py  -g '财务系统'  -G 'Disk space usage /data' -c 3 -n '财务系统---Disk space usage /data'


对于以上命令中的参数解释：
-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"财务系统"组里面每个服务器的bond0网卡、load负载、磁盘等监控图形，接每列4个图形（磁盘的按美3个图形）的显示在聚合图形里。

同理：如果添加其他主机组，即将上面的"财务系统" 统一替换掉即可！
