Zabbix 4.4.3 http agent LLD discovery JSON + item prototype with LLD Macro

[michalb]

Hello all

First sorry for my english .

I'm working on teplate for LLD discovery JSON data from API and i have problem with creating item prototype.

For example :

I have LLD macro created from discovery with JSON path and value is hostname : example.host.net . When use this macro in item key prototype : hostname[{#MYMACRO}] , after discovery i have items with name like this : hostname["["example.host.net"]"] . It's possible to remove backslashes and quotes ? . When i try use this macro in item prototype http agent and place this macro in URL path , path not correct . Path is : /somewhere/["exmaple.host.net"]/anywhere .
Any idea how to make work ?

Many thanks for help me .

Regards
Michal

And I have the same problem, can someone on this forum know the solution?

Hi, can you add the JSON file and screenshots of the discovery preprocessing and LLD macros config?

This is because you are generating the wrong json. As gert.derouck wrote - show the original json.

Hi , my solution is using regsub on LLD macro . You can find this function on Zabbix manual page ( i'm using 4.4 ) . Syntax is :
{{#LLDMACRO}.regsub(pattern, output)} Simply place macro to the path on item prototype with this function . I'm using regex ([\'"])(.*?) . Match group 2 and working good . Michal

This is not wrong JSON , this problem is on for example on API : NETBACKUP and Unify controller . :-)

Just as you say. I saw similar behavior of LLD when I configured it. And the reason was the wrong json structure.

Hamardaban : Yes i'm understand thanks for comment , JSON data verified by JSON validator and it's OK .

This will not work with LLD discover and JSONPath construct
