I've been having some trouble recreating an aggregation in kibana. I have the following elasticsearch agg I would like to recreate but I can't figure out how to make sub buckets and take the max from them in kibana (v6):

```
{
  "query": {
    "range": {
      "time_stamp": {
        "lt": "now",
        "gte": "now-1d"
      }
    }
  },
  "aggs": {
    "events_by_host": {
      "terms": {
        "field": "cell_host_the_app"
      },
      "aggs": {
        "events_by_date": {
          "date_histogram": {
            "field": "time_stamp",
            "interval": "30m"
          },
          "aggs": {
            "total_cpu": {
              "sum": {
                "field": "cpu_usage
              }
            },
            "max_cpu": {
              "max": {
                "field": "cpu_usage"
              }
            }
          }
        },
        "max_aggregated_cpu": {
          "max_bucket": {
            "buckets_path": "events_by_date>total_cpu"
          }
        }
      }
    }
  }
}
```

hi @Motez_Musa,

you can create sub-aggregations by adding more buckets in the Data panel. They are evaluated hierarchically. For the leafs, (in your case, the `total_cpu` and `max_cpu`, you would create metrics.

For example, using the Data Table aggregation I can create this query:

 ![image](https://us1.discourse-cdn.com/elastic/original/3X/2/4/2460a64988d1b258f8e3af5c7157797dac1be5b3.png)

Which would result in a query that pretty much looks like yours. The U2 -\> X doesn't let you specify the identifiers for the aggregations, Kibana uses incrementing integers. so for you, they would map to

2 -\> `events_by_host`  
3 -\> `events_by_date`  
1 -\> `total_cpu`  
4 -\> `max_cpu`

(of course, the field names in my index are different from yours)

```auto

  "size": 0,
