Apologies, I haven't updated the codebase to support 3.2 yet. There were breaking changes in Zabbix again.

Please note that I have abandoned this project after issue #5, as goroutines become unstable after the Zabbix agent forks. If you still would like me address your issue, I can create a v3.2 fix.
