Zabbix calculated item on failed step scenario not working

[leoonardoo]

I'm trying to setup a calculated item based on "Failed step of scenario". So I tried:

last("web.test.error[MyScenario]")

But it didn't work, the error message is:

Cannot evaluate expression: "Cannot evaluate function "last()": not enough data.".

While on the same scenario the "in" works with no problems:

last("web.test.in[MyScenario,,bps]")

Why? How can I translate a problem in the web scenario to a very simple 0(down)/1(up) calculated item???

YES! I was using the wrong item, I meant to use "web.test.fail" not web.test.error !!!

Thank you!

Ehh.. again .. documentation, documentation, documentation..

Last error message of scenario <Scenario>

This item returns the last error message text of the scenario. A new value is stored only if the scenario has a failed step. If all steps are ok, no new value is collected. Item key: web.test.error[Scenario] Type: Character

If your scenario has not had any errors, you don't have any data to evaluate, exactly as error says. And for creating a trigger, this item is pretty useless. You should use web.test.fail[Scenario]<>0
