Trigger hysteresis

if an item flaps around the trigger-value you will have multiple "PROBLEM" -> "OK" -> "PROBLEM" -> "OK". To circumvent this using a hysteresis for the trigger is desireable.

({TRIGGER.VALUE}=0 & {Zabbix server:system.W510.sensors.temp.1.last(0)}>85) | ({TRIGGER.VALUE}=1 & {Zabbix server:system.W510.sensors.temp.1.last(0)}>75)

This trigger will fire as soon as temperature raises above 85 but will stay triggered until the temperature is lower 75.

TRIGGER.VALUE is a Zabbix-macro. It returns=0 if the current state is OK and returns=1 if the current state is PROBLEM.
