Can extract one result with discovery rules

[alexxowo]

Hi guys!
I'm new with zabbix, and I am trying to get the model name from a host, the host I am trying to get is a ubiquiti antenna. I am using the discovery rules to read through SNMP, which is being the correct thing, but I am obtaining two values with different SNMP indexes, but the content of the variable is the same, what interests me is to automatically obtain a single SNMP entry OID. Can I somehow filter the discovery in such a way that I can be left with just one? Now i am using Zabbix 5.4

The following JSON is the answer of my Discovery rule

[
{ "{#SNMPINDEX}": "7", "{#MODEL}": "LiteAP GPS" },
{ "{#SNMPINDEX}": "12", "{#MODEL}": "LiteAP GPS" }, <- i want delete that, or get only one for this data
]

if i use prototype item, it show conflict with same item key, because i'm getting the double result


thanks for you help, and sorry for my bad english!

Hi, alexxowo.
I'd create a text item with the same SNMP OID as your LLD rule, i.e. with the word "discovery" and macro {#MODEL}, and use JSONPath preprocessing:
$..['{#MODEL}'].first()
