Verify if {HOST.IP} is part of an calculated item value (list)

[ludoviclemoine]

Dear Zabbix Community,

I came across an issue recently and I wanted to ask you if you have any suggestions to this (or had similar use cases).

A calculated item has a value (list of objects), that looks like this:

["IP":"1.1.1.1","IP":"2.2.2.2"]

I want to create a trigger that fires when the value of the built-in macro {HOST.IP} is not found in this list. I have tried to do it several ways, through an item or a trigger, both with a syntax like seen below:

find(/host/my-calculated-item,,"regexp","\"{HOST.IP}\"") <> 1

But without success, as {HOST.IP} is not being resolved in this context (as per documentation). Apart from doing this externally, via API or maybe with a discovery rule, do you see any other option I could use to make this trigger work ?
The idea is to make a template and attach it to multiple hosts, so I am looking for a convenient solution that is not too greedy in terms of resources.

Thank you in advance for your ideas :-)

Kind regards,
Ludovic

We have similar need to detect if our devices have proper IP-settings. This is our trigger, manip1 item needs to contain either of those IPs: find(/THISISMYHOST/manip1,,"regexp","123\\.45\\.0\\.160|123\\.45\\.67 \\.40")=0
You could use usermacro to have same syntax for IP stored in template {$MACRO1} = ^123\.45\.0\.160$ {$MACRO2} = ^123\.45\.67\.40$ and use those macros in trigger.....

Hello Markosa,
Thank you for your feedback. If my understanding is right, you suggest to duplicate the value of "["IP":"1.1.1.1","IP":"2.2.2.2"]" into a user macro {$MACRO1} ?
If this is the case, we want to avoid this. We are now working on using an external Zabbix module (in-house dev proxy) to make the required API calls and do the comparison outside of Zabbix, then populate a file and setup an item with the comparison result, but if there is any solution that works from within Zabbix, we would be happy to try it.
Kind regards,
Ludovic
