Zabbix Trigger firing frequently, how to fix?

Question

Zabbix

There is a trigger
{Monitoring_App_Asterisk_zabbx_3:iax.peers.max(12h )}>{Monitoring_App_Asterisk_zabbx_3:iax.peers.last ()}=1
It compares the last value of iax with the maximum value for 12 hours, if it is less then the trigger fires
how to configure it like this, what if the trigger is in error for 2 minutes then report the error?

Answer 1

I solved it like this:
({Monitoring_App_Asterisk_zabbx_3:iax.peers.max(12h)}>{Monitoring_App_Asterisk_zabbx_3:iax.peers.last(#1)})and ({Monitoring_App_Asterisk_zabbx_3:iax.peers.max(12h)}>{Monitoring_App_Asterisk_zabbx_3:iax .peers.last(#2)})and
({Monitoring_App_Asterisk_zabbx_3:iax.peers.max(12h)}>{Monitoring_App_Asterisk_zabbx_3:iax.peers.last(#3)})and
({Monitoring_App_Asterisk_zabbx_3:iax.peers.max( 12h)}>{Monitoring_App_Asterisk_zabbx_3:iax.peers.last(#4)})=1
