Trigger for host down (beginner)

[Moulins]

Hi all,

I'm just starting to test Zabbix. I'm stuck with a little problem: my hosts are flagged "ok" even when agents are stopped or hosts disconnected.

I have the standard trigger "{Template_Linux:status. last( 0 ) }=2" set to "average". The hosts remain green in the dashboard view. Maybe I miss something important ?

{Template_Linux:agent.ping. nodata( 1200 ) }=1
20 minutes without activity

Many thanks for your answer pesadilla. Your solution works nicely.

I now discover another problem, but this is for another tread :)
