How to select LLD Macro field/path if there is no variable name to specify

[lars ds]

Title might not be entirely clear but the problem is quite specific. I want to create a discovery rule with the output shown here:

{
    "http_method": "GET",
    "results": {
        "ZABBIX_O365": {
            "": {
                "status": "up",
                "latency": 14.83416748046875,
                "jitter": 2.5383334159851074,
                "packet_loss": 0.0,
                "packet_sent": 3053780,
                "packet_received": 3052937
            }
        },
        "ZABBIX_INTERNET": {
            "": {
                "status": "up",
                "latency": 17.034366607666016,
                "jitter": 3.6004993915557861,
                "packet_loss": 0.0,
                "packet_sent": 3052927,
                "packet_received": 3052052
            }
        }
    },
    "vdom": "root",
    "path": "system",
    "name": "link-monitor",
    "action": "",
    "status": "success",
    "serial": "FGT60FTK",
    "version": "v7.0.9",
    "build": 444
}​

I need to create a macro that can be filled in with the values 'ZABBIX_0365' and 'ZABBIX_INTERNET'. These names won't be the same everytime so I cannot rely on filters or hardcodes values. Normally with jsonpath I would select a field and the LLD would figure out that for each value of that field it should fill in the macro. Since I Cannot select a field I am not able to fill in the LLD macro with these values. Any ideas on how to fix this?

In this case, you need a JS preprocessing:

output = Object.keys(JSON.parse(value)['results']).map(function(zabbix){
    return {"{#ZABBIX}":zabbix}
})
return JSON.stringify(output)​

Thanks SemiAdmin I will give this a try!
