Get ok notification after discovery item deleted

[The_Shadow]

Hi all,
i get this json with discovery rule and with array key called "components" i create item based on lld macro and prototype item.
All work perfect but the json array is empty when no problem are detected.
When the object array is not empty i get problem message but how can i get resolved message when the problem are resolved and the array came back empty?
Someone can help me
Thank you a lot

Hi, please can someone help me
Thank you

what do the trigger and item prototypes look like?

[PeterZielony]

if this is master item .. you could have another item prototype same way as for your original LLD (dependent) on this JSON to count the array if a problem exists (with preprocessing and json path that compares ID too). When you do data type - set it to numeric value (of the count)

something like this:
$[?(@.id=='{#PROBLEM_ID}' && @.status=='{#PROBLEM_STATUS}')].length()
(edit: syntax might be wrong - but you get the idea)

But .. whether using another item prototype is ok or not - cant tell as I don't know how you structured LLD macros and item prototype - same for macros and how your LLD works (but you can use syntax above to construct it in your scenario)

Then trigger recovery expression on this item if it 0 - problem solved, 1 - problem still exists.

I hope this make sense a bit.
json path supported functions:

https://www.zabbix.com/documentation/6.4/en/manual/config/items/preprocessing/jsonpath_functionality

.length() function

this won't work if "discovery item is deleted" though - it will exist until it is not discovered plus "keep lost resources for XYZ time" (discovery settings) - but this way it will set it as resolved as soon it disappear from discovery json

Hi, thanks for yours answer. I'm trying with @PeterZielony solution.
If can help, here the actual configuration

Discovery Rule main configuration:

Actual Preprocessing discovery rules:


Actual LLD Macros discovery rules:


Main of first prototype configuration:


Preprocessing for first prototype configuration:


Thanks a lot for new answer

Hi @PeterZielony ,
thanks a lot for your help.

I created master item as http agent type and preprocessing jsonpath equal to $.components
Than i created discovery rule depends on master item with this LLD macros


Then i created prototype item like this with preprocessing jsonpath equal to $.[?(@.id== "{#ID}")].length()


Then i created trigger prototype like this:


With this configuration i get this resolved notification



Do you know how to change "Operational data" value with the value inside LLD macro {#STATUS}?
Thank you

[PeterZielony]

I hope you got it sorted. I wasn't around for some time to check your answer (time off)

Add {#STATUS} to opdata line...
