How to add a metadata as top level property X instead of fields.X?

[ahmadferdous]

When I do
logger.info("something interesting", meta: "meta_value"),
I see on logstash meta property is placed inside fields i.e. fields.meta:

Is it possible to have that property meta as a top level property like host, message and type?

Indeed , a strong and valid point (which we came across today).
Other solutions do not add the 'fields' key and standarising data across platforms is a nice to have. we have modified

https://github.com/marcelog/logger_logstash_backend/blob/master/lib/logger_logstash_backend.ex#L73

to do the following:

 {:ok, json} = JSX.encode Map.merge(%{
      type: type,
      "@timestamp": Timex.format!(ts, "%FT%T%z", :strftime),
      message: to_string(msg),
    }, fields)

more than happy to make a pull request but will break backward compatibility 😄
