Hi all, I just figured out how to make an active agent on a host, all other hosts are passive and work fine with alerts and problems. One of the things i noticed is that when i take the host down i do not get an alert or problem regarding availability. I am a bit confused by this trigger 
I am not sure how to setup the nodata(). i am on zabbix 4.4. help is appreciated
