You can do this using a ruby script within a filter. See the answer [https://discuss.elastic.co/t/how-can-i-get-the-logstash-hostname/51771:](https://discuss.elastic.co/t/how-can-i-get-the-logstash-hostname/51771:)

```
filter {
  ruby {
    init => "require 'socket'"
    code => "event['some-field-name'] = Socket.gethostname"
  }
}
```

Hi, It works. I just change it to

ruby {  
init =\> "require 'socket'"  
code =\> "event.set('some field', Socket.gethostname)"  
}

Thank you so much!
