hi team,  
I have been working with metricbeat module and trying to get SUM (offset.newest)of topic by getting max from each partition. Seems like i just cannot get right SUM. here is the structure 🙂

```auto
"kafka": {
    "partition": {
      "broker": {
        "id": 1,
        "address": "localhost:9092"
      },
      "partition": {
        "replica": 1,
        "insync_replica": true,
        "id": 2,
        "leader": 1
      },
      "offset": {
        "newest": 2380344,
        "oldest": 0
      },
      "topic": {
        "name": "ABC.20181115"
      }
    }
  }

```

Hi,  
We need to know your fields/mapping in discover. May be use a scripted field ?[https://www.elastic.co/guide/en/kibana/current/scripted-fields.html](https://www.elastic.co/guide/en/kibana/current/scripted-fields.html)

Thanks  
Rashmi
