Visualizing nested objects

Elastic Stack Kibana
1

Hello...

I realized that there is no/limited support for aggregation on nested objects but I am hoping that there is a workaround for my problem.

My JSON document looks like

id 1

"aps": {

  "mac": "36",
  "radio": [
    {
      "slot": 0,
      "count": 10
    },
    {
      "slot": 1,
      "count": 100
    }
  ]

}

id 2

"aps": {
"mac": "36",
"radio": [
{
"slot": 0,
"count": 30
},
{
"slot": 1,
"count": 300
}
]
}

I would like to perform an aggregation on these documents. For example,

compute the average value of count but split it based on slot.

So with the above I would get two values

avg_slot_0 = 20

avg_slot_1 = 200

Is there a way to do this?

I do realize that I can make this work by splitting each document and storing it based on each radio but for various reasons I cannot do that.

I am hoping to make it work without splitting.

Thanks in advance.

it seems kibana doesn't yet deal with nesting or parent/child object.
