Get data from UserParameter as JSON and parse with LLD

[artyomtsybulkin]

Hello! I'm beginning with Zabbix 4.0. I find many topics about LLD but nothing helps me. Documentation uses very simple examples with built-in key settings and nothing about customized LLD process.
My scenario:
1. I use remote Active agent behind the NAT.
2. In agent config running this script:
UserParameter=script.memory,powershell C:\Zabbix\Deploy\Example\x64\satellite.ps1 hardware memory
3. I test it with zabbix_get:
{
"data": [
{
"{#SPEED}": 1600,
"{#DEVICE}": "ChannelA-DIMM0",
"{#CAPACITY}": 8589934592
},
{
"{#SPEED}": 1600,
"{#DEVICE}": "ChannelB-DIMM0",
"{#CAPACITY}": 8589934592
}
]
}
4. Next I want to create discovery rule that will make items from prototypes like this:
1) Name=Speed for {#DEVICE}, Value=1600
and
2) Name={#DEVICE} capacity, Value=8589934592.

5. In discovery rule i set key: script.memory, and filters {#SPEED} AND {#DEVICE} AND {#CAPACITY}.

Questions: is my setup right or not? What settings I must implement in rule and item prototypes to complete this task?
Thanks

The discovery rule will bring back the associated jobs pairs. You the add discovery items using the discovery names is {#speed}.
for every json key pair the discovery rule gets back it will create an item.
