How to configure a good last 3 values trigger. Mine is not working as expected

[waardd]

The trigger fires when 1 of the three dependencies is met.
So in this example

The trigger is:
{Template x:Avg["POLLER_CHANGED_CST: Trigger Changed .. Handled"].last()}>30000 and {Template x:Avg["POLLER_CHANGED_CST: Trigger Changed .. Handled"].last(#2)}>30000 and {Template x:Avg["POLLER_CHANGED_CST: Trigger Changed .. Handled"].last(#3)}>30000

In database the values are:

2016-10-09 09:29:59;303995.0
2016-10-09 09:19:59;2794.0
2016-10-09 08:49:59;1379.0

Trigger went off on the high value and should not go of because the 2 previous are < 30000

What am i doing wrong.

Zabbix version is 2.4

Offhand, I'm not sure why that's not working the way you expect. However, you can simplify the expression greatly by simply using the min() function:


{Template x:Avg["POLLER_CHANGED_CST: Trigger Changed .. Handled"].min(#3)}>30000

That says, if the minimum value over the last 3 intervals is greater than 30000, then fire. As long as one of the values is beneath the threshold, you should be OK.
