I read about the use of the [@metadata] field in the 1.5 version ([https://www.elastic.co/blog/logstash-metadata](https://www.elastic.co/blog/logstash-metadata)) and wanted to try it out on logstash 2.0. Unfortunately, there seems to be no way of forcing to output metadata fields in the output{} filters.

Is the the use of [@metadata] still recommended in version 2.0 or is it deprecated?

The [rubydebug codec](https://www.elastic.co/guide/en/logstash/current/plugins-codecs-rubydebug.html) has an option to include `@metadata`. That the outputs ignore that field is the whole point.

It's not deprecated.

As @magnusbaeck has pointed out, `@metadata` was designed specifically to _not_ output. You can copy anything out of `@metadata` with mutate and sprintf formatting, as appropriate.
