# Logstash X-Pack

Set of plugins that form Logstash X-Pack features.

# Setup

Logstash X-Pack features are a default part of Logstash; as X-Pack features provide integrations with the rest of the Elastic Stack, they will need to be configured to point to an Elasticsearch instance in order to work.

## Opting Out of X-Pack

If you are unable or unwilling to run the Elastic-Licensed X-Pack Features and Functions, OSS-only distributions are available from the [downloads page][]; to run Logstash from source without X-Pack, ensure that your environment variable `OSS` is exported with a value of `true`:

~~~ sh
export OSS=true
~~~

[downloads page]: https://www.elastic.co/downloads/logstash

# Configuration

To configure x-pack settings, you can edit config/logstash.yml and add `xpack.*` configs from the [logstash x-pack settings][].
