Event when something doesn't happen

[jeroen_vdk]

I was wondering if somebody could point us in the right direction to have an event/alert/trigger when something doesn't happen each day without input.

For example if (veeam) backup script doesn't run/finish/output before 6 AM, there should be an alert even there is totally no output because the agent or veeam hangs ?

Same with for example oracle rman script, if script doesn't run last night because something "hangs", i want to have an alert to prevent other issues. We want to see something that doesn't have an input...
I don't know how to search for this.

Using version : Zabbix 4.4.3

I'm not a Zabbix specialist at all, but if you're trying to detect whether you receive data from a client, it would seem that .nodata() is what you're looking for.
So if you want to alert when you received nothing from your Veeam script for, let's say 2 hours, you can have a trigger like this:

{Template Veeam:veeam.backup_result.nodata(2h)}

Regarding having it checked specifically before 6AM, there's a wiki page about time periods, but it doesn't say where it's supposed to be used/applied, so I'll let more-knowledgeable people answer that.
