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
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。
