The JSON input you provide is merged with the aggregation parameters from Kibana. (thats why you have that field on each aggregation) You need to lookup the [Elasticsearch documentation](https://www.elastic.co/guide/en/elasticsearch/reference/current/search-aggregations.html) for the kind of aggregation you're using to figure what you can do. For instance, for the Significant terms aggregation, it can be useful to modify the background\_filter property to make the significant terms relate to only a subset of your index.  
Or maybe you want to pass shard\_size in a terms agg, or increase the precision\_threshold in a cardinality agg.

We can also pass a script as an advanced parameter to some aggregations, and for example divide \_value by 1000.  
If you select average as your metric type (instead of count) you can for example try with this script:

```auto
{
  "script" : 
    {
    "lang": "painless",
    "inline": "_value / params.correction",
    "params" : {
      "correction" : 1000
    }
  }
}

```

make sure you provide valid JSON.
