object loop

[yosefy]

hi we have this from nginx unit state

    "connections": {
        "accepted": 245214,
        "active": 0,
        "idle": 0,
        "closed": 245214
    },
    "requests": {
        "total": 245178
    },
    "applications": {
        "site2.com": {
            "processes": {
                "running": 1,
                "starting": 0,
                "idle": 1
            },
            "requests": {
                "active": 0
            }
        },
        "site1.com": {
            "processes": {
                    "running": 1,
                    "starting": 0,
                    "idle": 1
            },
            "requests": {
                "active": 0
            }
        }
    }
}```

so we need add metrics adding "application name" as label

I came across similar situation:

---
modules:
  device_stats:
    metrics:
    - name: status
      help: Connected Switches
      type: object
      path: '{ @ }'
      labels:
        status: '{ .status }'
      values:
        return: 1

    - name: list_of_interfaces
      help: list interfaces
      type: object
      path: '{ @.if_stat.* }'
      labels:
        ifname: '{ .port_id }'
      values:
        return: 1

JSON:

{
   "status": "connected",
    "hostname": "X",
    "if_stat": {
        "em0.0": {
            "tx_pkts": 238084479,
            "rx_pkts": 187104366,
            "rx_bytes": 28492395648,
            "port_id": "em0",
            "up": true,
            "tx_bytes": 144260009035
        },
        "irb.80": {
            "tx_pkts": 133010,
            "vlan": 80,
            "rx_pkts": 41813989,
            "rx_bytes": 14102487191,
            "port_id": "irb",
            "up": true,
            "tx_bytes": 7384805
        }
    }
}

I tried to iterate the interface however received the errors:

19 error(s) occurred:
* collected metric "list_of_interfaces_return" { label:{name:"ifname" value:"irb"} untyped:{value:1}} was collected before with the same name and label values
* collected metric "list_of_interfaces_return" { label:{name:"ifname" value:"irb"} untyped:{value:1}} was collected before with the same name and label values
* <snipped>

Would it be possible or is there a way that if we can iterate the nested object so that the metric comes like below?

list_of_interfaces_return{ifname="em0"} 1
list_of_interfaces_return{ifname="irb.80"} 1
