Item Prototype Discovery JSON

[focar]

Hello

I'm struggling with a discovery process and cannot get it to work properly. I'm pretty sure it is a PEBCAK problem but i hope someone can help me.

I got this JSON object:




i need to discover the client_name and service_name. And the value[1] is the item that needs to be monitored.

So far i got it right for the name and service name. This is discoverd well, but the value seems to be the tricky one.


Discovery Rule:

Preprocessing steps :
JSONPath $.data.result[*]

LLD Macros :
{#CNAME} $.metric.client_name
{#SERVICE} $.metric.service_name
{#VALUE} $.value[1]



Item Prototype:

key lynx_svc.util[{#CNAME}{#SERVICE}]
type float

Preprocessing:
JSONPath $.{#VALUE}


I get this error on item:

Cannot update item: invalid value for preprocessing step #1: unsupported construct in jsonpath starting with: ""9.82"]". \\\

It looks like it is showing the correct value in the error. I'm pretty sure it is a syntax error in my construct but i tried several but nothing seems to do the job for me

What could i be missing here? Many thanks

Hey,

After some searching and comparing with existing JSONpath configs i got it working. For whoever this is helpful, this is the parameter is used in the item property:

$..[?(@.value[1] == "{#VALUE}")].value[1].first()


Now i have another issue with the type that is returned but i will figure that out.
