How to parse jolokia response into Elasticsearch using logstash

Question

I'm trying to create a logstash pipeline that polls a ActiveMQ jolokia endpoint. I'm wanting to collect all the metrics for the queues on the broker. I have the following pipeline.

input {
  http_poller {
    urls => {
      health_metrics => {
        method => "get"
        url => "http://localhost:8161/api/jolokia/read/org.apache.activemq:type=Broker,brokerName=localhost,destinationType=Queue,destinationName=*"
        headers => {
          "Content-Type" => "application/json"
        }
        auth => {
          user => "admin"
          password => "admin"
        }       
      }
    }
    request_timeout => 30
    keepalive => false
    interval => 5
    codec => "json"
    type => "activemq_broker_queue"
  }
}

filter {  
    json_encode {
      source => "value"
    }
    json {
      source => "value"
    }
    mutate {
      remove_field => ["request", "value", "timestamp"]
    }

}

output {
  elasticsearch {
    hosts => "localhost"
    # An index is created for each type of metrics inpout
    index => "logstash-activmq" 
    document_type => "%{type}" 
  }
   stdout {
    codec => rubydebug
  }
}

My jolokia response is in this format.

{
    request: {
        mbean: "org.apache.activemq:brokerName=localhost,destinationName=*,destinationType=Queue,type=Broker",
        type: "read"

        }
    },
    timestamp: 1453588727,
    status: 200
}

I would like to be able to split the two queue destinations into two different documents and then save them to ES.

Currently I'm get an error about cannot contain '.'
