zabbix 之所以能成为比较优秀的监控工具，个人觉得是因为两个特点：一个是数据的存放方式，方便做数据处理，容量规划，归档等，这个之前说过。另一个是其强大的 api，利用其 api 可以方便的和其他的组件进行整合，比如 cmdb 可以通过 zabbix api 来实现监控的添加，更新和禁用等，zabbix 的官方文档提供了比较详细的 api 列表。
因为最近添加 screen 的需求比较多，就简单写了一个 Python 脚本用来自动化添加 screen，有兴趣的可以借鉴下。
使用方式如下：
python ./screen_host.py -H 主机列表 -n screen 名称 -G graph 名称
具体的脚本：
#!/usr/bin/env python
