需求:对所有云主机添加公网带宽监控,但不是每一台主机都有公网IP,有公网IP的主机的带宽也不完全相同,比如有的是1M,有的是5M,带宽监控的阈值为带宽值*0.8。例如1M的带宽,监控的阈值为0.8M。(注意:经过测试,在zabbix的trigger中这是0.8M,不会发出告警,但是阈值为大于1M的小数时又可以告警,怀疑是小于1M时,zabbix自动将单位换成K导致的。后来索性在定义带宽监控阈值时将单位统一为K,并且一定要为整数。如1300K可以,但是1300.5K则不会告警。)
脚本思路:监控阈值在每台主机上去添加主机宏,不是手动添加,而是通过zabbix API为主机添加宏。
具体的过程如下:
通过CMDB接口拿到所有主机的信息,包括zabbix主机可见名和带宽信息,做判断,公网带宽为0M时,不添加主机宏。当不为0M时,先判断主机上是否存着这个宏,如果不存在则创建这个宏,如果存在,先比较该宏的值是否和由的带宽值计算出的告警阈值相等,如果相等,表示带宽没有更新过,不做处理。如果不相等,则表示带宽是调整过的,需要更新主机宏上的带宽阈值。
