How to monitore last contact with an active client

[Bubbleman]

Hi together,

is it possible to make a trigger if an active client don´t send any Datas for example 14 Days? The problem is that we have a view Clients which only can monitored active, but I get no information if they send any datas in the last few days.

Please help me :-)

Thanks a lot
Kind regards from Germany

See nodata() trigger function.
Zabbix server every 30 seconds automatically calculates all the triggers contain this function.
