由于最近在研究zabbix，学习python，于是就拿python练练手，写了下面这个脚本
脚本作用：发送tigger内容并附加发送tirgger所对应的graph
脚本思路：通过zabbix传递的"Default subject"取出触发的tirgger对应的主机host，以及对应的graphname，通过host和graphname在数据库中查询出所对应的graphid，之后通过graphid使用curl通过web页面下载对应graph的图片，最后将图片作为邮件内容发送出去。
脚本依赖：由于获取host和graphname依赖于zabbix传递的参数形式及内容，所以需要做如下设置
设置1：修改tirgger名字和graph名字对应，grap名字中不包含tirgger中所使用的宏，如：
tirgger名：Running processes on {HOST.NAME}
graph名：Running processes on
设置2：创建Actions时，"Default subject"和"Recovery subject"要设置为："{HOST.NAME1} {TRIGGER.STATUS}: {TRIGGER.NAME}"
设置3：在zabbix上创建一个具有只读权限的用户，在zabbix数据库上创建一个具有查询权限的用户
脚本进度：由于个人技能还未达到一定的层次，该脚本在手动执行是正常的，但是在zabbix的Action触发调用时，却不能成功执行，希望有兴趣的朋友给我一些建议和指导，或者为我指出哪里考虑不周全导致的脚本不能正常执行。希望能够得到广大IT爱好者的帮助与建议。
