Creating a trigger for a heartbeat SNMP trap

[b3owu1f]

Hello guys,

I have a problem I don't know how to approach.
I have set up triggers for SNMP traps, but there's one special case that I don't need the trigger to start when I receive the SNMP trap.
This trap is sent as a heartbeat, every 60 seconds to Zabbix. So what I need to do is that the trigger starts when I don't receive one of these trap messages in a period of 120 seconds.
Can anyone give me some guidance on how to do that?

The nodata() function is great for that. For example, nodata(/myhost/mykey,5m)=1 triggers when there haven't been data received for mykey in 5 minutes.

That worked perfectly, thank you!
