Requirements: Add public network bandwidth monitoring for all cloud hosts, but not every host has a public IP, the bandwidth of the host with public IP is not exactly the same, for example, some are 1M, some 5M, bandwidth monitoring threshold is the bandwidth value *0.8. For example, 1M bandwidth, the monitoring threshold is 0.8M. (Note: After testing, in the Zabbix trigger this is 0.8M, will not issue an alarm, but the threshold is greater than 1M of the decimal can be alarm, suspect is less than 1M, Zabbix automatically change units to K caused. Then simply define the bandwidth monitoring thresholds by unifying the units to K, and be sure to be integers. 1300K is possible, but 1300.5K does not alarm. ）

Scripting Ideas: Monitoring thresholds Add host macros to each host, not manually, but add macros to the host through the Zabbix API.

The specific process is as follows:

Through the CMDB interface to get all the host information, including Zabbix host visible name and bandwidth information, make a judgment, the public network bandwidth of 0M, do not add host macros. When not 0M, first determine whether the host is stored on the macro, if it does not exist, create this macro, if present, first compare whether the value of the macro and the bandwidth value calculated by the alarm threshold is equal, if equal, indicating that the bandwidth has not been updated, do not do processing. If they are not equal, the bandwidth is adjusted and the bandwidth threshold on the host macro needs to be updated.
