I would like to append hostname in each index name for classification of files based on the source hostname.
```auto
output{
elasticsearch {
hosts => ["127.0.0.1:9200"]
index => "sample-%{[@metadata][hostname]}-%{[@metadata][beat]}-%{[@metadata][version]}-soap2-%{[@metadata][beat]}-%{+YYYY.MM.dd}"
}
}
```
This metadata is not working %{[@metadata][hostname]};

You might not have a field called `hostname`.
Add this to your output and it will show you all the `metadata` fields available.
` stdout { codec => rubydebug { metadata => true } }`
