I'm using the json filter plugin and want to exclude parsing part of the message into JSON  
[https://www.elastic.co/guide/en/logstash/current/plugins-filters-json.html](https://www.elastic.co/guide/en/logstash/current/plugins-filters-json.html)

```
filter {
        json {
            source => "message"
        }
}

```

For example, below is an example JSON `message`. How can I keep the `Event` field as a string (as in tell json filter plugin to do not parse `Event` content, just keep as a string)

`{"timestamp":"2016-08-12 14:10:52,385","level":"INFO","logger":"com.MyClass","thread":"Thread-48","Event":{"field1":"Value1","field2":"Value2"}}`

or is there a way to convert Event back into a String and add as a new field
