== Logstash Forwarder
[float]
=== status: ongoing; v2.x
=== status: ongoing
Logstash Forwarder uses a different code base from Logstash, and as a result it
has been a challenge for us to keep feature parity between the two projects. We
are experimenting with unifying the two code bases to improve ongoing
maintenance of the Logstash Forwarder. Currently, Logstash Forwarder is written
in Go and Logstash is written in Ruby and runs on JRuby. We are investigating
the feasibility of replacing Logstash Forwarder with Logstash Ruby code executed
on Matz Ruby Interpreter (http://en.wikipedia.org/wiki/Ruby_MRI[MRI]). Important
criteria for success in this POC is to keep Logstash Forwarder lightweight and
still distribute it as a binary so it doesn’t introduce language dependencies on
the servers where it is deployed. You can follow this effort on GitHub through
the Logstash Forwarder
https://github.com/elastic/logstash-forwarder/issues[issues list].
While we are working on these enhancements, we are committed to maintaining the
Logstash Forwarder. We recently delivered
http://www.elasticsearch.org/blog/logstash-forwarder-0-4-0-released/[Logstash Forwarder 0.4.0],
which addressed many existing issues our users have been reporting.
https://github.com/elastic/logstash-forwarder/[Logstash Forwarder] is a lightweight shipper for tailing files and forwarding this data to Logstash for further processing. It is often used in lieu of running Logstash on the servers, because it is lightweight, written in Go, and consumes less resources. It was created before we had the Beats framework for shipping data from servers and is currently maintained separately. We plan to move the Logstash Forwarder functionality to https://github.com/elastic/filebeat/[Filebeat] in the Beats framework, which is also written in Go. The first version of Filebeat will leverage the libbeat infrastructure and preserve existing features. Over time, we plan to enhance Filebeat with capabilities such as multiline and filtering support. Since Filebeat will serve as the direct replacement for Logstash Forwarder, we are not planning additional releases beyond http://www.elasticsearch.org/blog/logstash-forwarder-0-4-0-released/[Logstash Forwarder 0.4.0].
