Value not interpolated in trigger name

[john_lynch]

Hi all...

I am new to Zabbix, and my first task is to fix an issue with a trigger name.

We have the

{ITEM.LASTVALUE}

macro in a trigger name, but the code gets rendered literally, i.e. the value is not interpolated. (See first screenshot.)

I first tried to use

{HOST.HOST}, {HOST.IP} and {HOST.DESCRIPTION}

in the name, but none of these worked either - only

{HOST.HOST}

works out of these 4.

If I look at "Event Details", I see the string rendered correctly (see 2nd screenshot) but when I receive the data via the API, I get

[11] => stdClass Object (
    [triggerid] => 29010
    [expression] => {46420}>30
    [description] => High number ( {ITEM.LASTVALUE} ) recordings not uploaded on finland-nuc.spearline.com
    [url] =>
        ... 

The documentation at https://www.zabbix.com/documentation...ed_by_location clearly states that it is supported in Trigger names and descriptions.

I'm guessing I may be missing something obvious. After considerable searching I seem no nearer to finding the solution. Can anyone help please?

TBH, I have never tried it.. but maybe its one of these

expandComment	flag	Expand macros in the trigger description.
expandDescription	flag	Expand macros in the name of the trigger.
expandExpression	flag	Expand functions and macros in the trigger expression.
