How to add a trigger in zabbix that inform me that other triggers are set to unknow?

Question

I am recently trying to add a trigger in zabbix that inform me that other triggers are set to unknow. When there is a trigger set to uknown then this trigger will print a issue in "Last 100 issues". Do anybody know how i can do this?

Answer 1

It does not seem to be possible to make such a trigger, but the same can be achieved using internal events that are supported since Zabbix 2.2 (see What's new in 2.2.0 and Events for details).

Answer 2

Also you can obtain non-detailed info of total count of unsupported items using internal self-monitoring: zabbix[items_unsupported]

And set a trigger like {Zabbix_Server:zabbix[items_unsupported].change(0)}>0
