Trigger activate after x minutes when value exceeds x

[JackoAC]

Hello,
I have a little question.

I'm using Zabbix 6.0 on Debian 11.
i have a template that monitor my mail Q.

My values appear like this



values are then separated according to the spools. (incoming, filtering, outgoing)
I have triggers that activate when the number of mails in one of the Q exceeds 9.

But I would like to avoid false positives and say that the trigger only activates if the value is greater than 9 for 5 minutes
I tried with different trigger but it doesn't work as intended

For example with this trigger "count(/<template>,300)>=3" the trigger fired directly while my data is at 2 and only after 30 seconds.

Can someone Help me ?

Thank in advance

Look at the documentation for the trigger functions, in particular the min() function. In fact, the very first example in the Trigger expression section of the documentation shows an example similar to what you want to do: "the min value is greater than X for 5 minutes". The list of functions and what arguments they take is available in the link in the "Functions" section of that page.

Hello, thank for the your answer.
i tried with the documentation you just send and it work, i just needed to change the format of data (text to number) so i could have the min function.
