elasticsearch - Parsing JSON with Logstash -

i'm having problems parse json elasticsearch logstash:

{   "type1": {},    "type2": {     "id": {       "param1": value1,        "param2": value2,        "param4": value3,        "param4": value4,        "param5": value5     }   },    "type3": {} } 

i'm using logstash config:

input {   http_poller {     urls => {       data => "http://blablah/json_data"     }     request_timeout => 10     interval => 15     codec => "json"   } }  output {   elasticsearch {     hosts => ["localhost:9200"]   } } 

i want map "type" elastic "_type" value, , "id" elastic "_id" value, cant achieve that.

i've read tons of doc filters , grok , head explode.

any apreciated :)

edit: expected output

{   "_index": "logstash-16.07.21",   "_type": "type2",   "_id": "id",   "_score": 1,   "_source": {     "id": {       "param1": value1,       "param2": value2,       "param3": value3,       "param4": value4,       "param5": value5     },     "@version": "1",     "@timestamp": "2016-07-21t16:12:29.716z"     "param1": "value1",     "param2": "value2",     "param3": "value3",     "param4": "value4",     "param5": "value5"   },   "fields": {     "@timestamp": [       1469117549716     ]   } }
