Trigger event name with expression macros

[markfree]

Hey guys.
I've created an SNMP fallback item and a few dependent items from it.

SNMPTRAP
|--SNMPTRAP Info
|--SNMPTRAP Serial
|--SNMPTRAP Severity
|--SNMPTRAP Title

Now I wish to create more meaningful triggers with those dependent items.
For that I tried to use expression macros in the "event name" field, but they are not resolving correctly.

According to documentation, some functions are allowed as trigger event names.

As an example, the following trigger checks if the trap severity item is higher than 4, and the event name should use the trap title item.


The issue is that, when my trigger is true, the generated event does not resolve correctly the defined expression macro.


Any tips on how to enhance that trigger?

It seems that expression macros are having lots of problems at the moment, here in the forums and in support.zabbix.com, at least:

https://support.zabbix.com/browse/ZBX-21266

https://support.zabbix.com/browse/ZBX-21922

If you think your usage is correct, just open an issue and describe your case (or, try to have meaningful additions to existing issues, and remember to vote for the relevant issues), let's see then

I'll look into it. Thanks.

The fact is that dependent items are not obtained by zabbix at the same time. If you are lucky and Severity received a few nanoseconds later than Title, then everything is ok, otherwise you get Title from the previous event

That's true, indeed. A few traps were triggered as expected; others did not. Thanks.
