Hello,
I've configured Filebeat on application host and ELK stack on another. Everything working good, but i have just beat.hostname and [beat.name](http://beat.name) fileds in Logstash.
Is there a way to retrieve IP address of my application host?

Currently Filebeat doesn't export the IP address, but you can configure Filebeat to add an additional field that contains a static IP address that you configure in each configuration file. Please check [fields option](https://www.elastic.co/guide/en/beats/filebeat/current/filebeat-configuration-details.html#configuration-fields).
fields:
ip\_address: 192.168.3.4
If this doesn't help you, feel free to open a new feature request [here](https://github.com/elastic/beats/issues).

You should be able to access in the same way as any other field with `fields.ip_address`.

1. accessing variables in logstash is via `[fields][portvariable]`
2. what's samplevar option in beat input plugin? This config option is not supported by logstash
See logstash config docs + ongoing sub-chapters for logstash config file syntax: [https://www.elastic.co/guide/en/logstash/current/configuration-file-structure.html](https://www.elastic.co/guide/en/logstash/current/configuration-file-structure.html)
For manipulating events check out the docs filters section.
