The server is Zabbix agent in UserParameter stands for simple scripts (executed during normal operation less than a second)
Customize "NODATA" triggers:

{Template: any.element.nodata (900)}

Tell me, please, correctly created the triggers necessary to correct validation scripts or release the load on the wheels?

The forum did not find anything for my problem.
