trigger fires on the "wrong" value

[sitnikov]

Trigger event



Trigger config




{$SUPPLY_WATTER_HIGH_LIMIT} == 18

I don't understand why the trigger was fired.


Zabbix 5.2.6

Can you post a graphic of this item?

Sometimes the average value is above the limit, but the last value is less than the limit

To solve this problem, change the average function to minimum. Thus, the lowest value collected will be analyzed and not their average.

If in the last 5 minutes the lowest value is 18, probably this metric has already crossed the limit

Try make the changes I said and tell me the result

I understand this workaround. I'm more interested in why is {ITEM.VALUE1} below 18 (as we can see in description) and trigger fired

Because the macro will show the item's value at the moment the trigger is fired.

And the most recent value is not necessarily higher than the configured limit value.
