How to set Trigger to send alert after 15 mins?

[NewUser1]

Hello,

I have two triggers set for when the cpu reaches 80% and 90% they work fine but I want to make it that they send an alert after the cpu has remained above 80% or 90% for 15 minutes.

Here is the expression I got for 80%

min(/Windows by Zabbix agent/system.cpu.util[all,system,avg5],15m)>80

Here it is for 90%

min(/Windows by Zabbix agent/system.cpu.util,15m)>90

Where am I making a mistake with my expressions?

Mistakes?

2 different items? "system.cpu.util[all,system,avg5]" and "system.cpu.util" ?

Other thing is .. that first trigger should consider values between 80 and 90 and other one values over 90... so your first one should be "min(item,15m)>80 and max(item,15m)<90" and the other one just "min(item,15m)>90"

What I meant is that one of my triggers is for when the cpu hits 80% and my second trigger is for when the cpu hits 90%. What I want is for both triggers to trigger only after they have remained at their respective percentages after 15minutes or longer.

So I assume that the expression for 80% should look like this "min(/Windows by Zabbix agent/system.cpu.util[all,system,avg5],15m)>80"

and for 90% should look like this "min(/Windows by Zabbix agent/system.cpu.util,15m)>90"

if you are wondering why I didn't use "system.cpu.util" for the 80% expression it was because it was being used for the 90% expression that was prebuilt already. I had to make this expression for the 80% "system.cpu.util[all,system,avg5],15m)>80"

Looks fine to me.."min (/host/key,(sec|#num)<:time shift>)"
Do you have any suspicions, that it does not work?

You can use same item in multiple triggers...
