Unsupported JSON path - Zabbix 6.0

[um3n]

Hey guys,

i'm reaching some point of frustration with jsonpath and LLD discovery.

I'm trying to monitor some milestones in our gitlab environment. I query the gitlab api with a http agent discovery item.



The testquery gets me a result.



I created an itemprototype with this, but the items will not be created.



I get this error:

Cannot create item: invalid value for preprocessing step #1: unsupported construct in jsonpath starting with: "[22]].state".
Cannot create item: invalid value for preprocessing step #1: unsupported construct in jsonpath starting with: "[15]].state".
Cannot create item: invalid value for preprocessing step #1: unsupported construct in jsonpath starting with: "[14]].state".
Cannot create item: invalid value for preprocessing step #1: unsupported construct in jsonpath starting with: "[13]].state".
Cannot create item: invalid value for preprocessing step #1: unsupported construct in jsonpath starting with: "[12]].state".

If I escape the ID LLD macro in the prototype, zabbix will start create the items, but cannot query them, because the LLD macros will be stored with square brackets.
I also tried the mentioned solutions from this thread, but this does not work either.

Any ideas?
Thanks and kind regards,

Ulli

Hey guys,

I hope you can help me, when I post some more infos.

When I use some escaping, the items can be created by zabbix, but jsonpath couldn't get values and the items will be unsupported.







I need some help. We don't want to create an external script

i solved it myself with a not so great solution but it works.

In the discoveryrule I added two preprocessing steps to replace the square brackets. In my case it works, cause there are no arrays in the response. If you have some arrays in your json response, that will not work!

what was the replacement?

If the returned value of the item is an array, I think you can use the Trim preprocessing instead.
