   Hi all,
   @ahsanshah , @mistercrunch 
   I am not yet able to create my druid average metric in superset.
   I have a question regarding the different fields to fill when i create druid metric.
   ![image](https://user-images.githubusercontent.com/14936795/44524144-ad946680-a6dc-11e8-8fc8-067a3a1a1a7a.png)
   In the screenshot above could you confirm that i have to put my query to the JSON field ?
   I know that i have to select my druid Datasource on the dropdown list .
   What should i replace the three points at the beginning and at the end of my query below ?
   {
   ...
     "aggregations" : [
       { "type" : "count", "name" : "rows" },
       { "type" : "doubleSum", "name" : "tot", "fieldName" : "total" }
     ],
     "postAggregations" : [
       
          { "type"   : "arithmetic",
            "name"   : "div",
            "fn"     : "/",
            "fields" : [
              { "type" : "fieldAccess", "name" : "tot", "fieldName" : "tot" },
              { "type" : "fieldAccess", "name" : "rows", "fieldName" : "rows" }
            ]
          }
     ]
     ...
     }
   Why i don't have the metrics which are present in my druid data source?
    I have juste the count(*) metric as shown on the screenshot below.
