I have a Logstash conf where I split an incoming XML into multiple events. I would like to write a file per event. However, the file output writes all the events to a single file (so an event per line). Is there a way to achieve this?

```
filter {

xml{
   store_xml => "false"
   source => "message"
remove_namespaces => true
xpath => 
 [
"/root/Envelope", "Envelopes"         
   ]
  }

mutate {
    remove_field => ["message"]
  }

 split{
  field => "Envelopes"
 }
}

output {
file {
path => "/install/logstash/output-CL102-%{+yyyyMMddHHmmss}.xml"
}
}

```

Thanks

If the sprintf format string provided to the file output plugin's `path` directive creates unique value per event, then you will effectively write exactly one event per file.

One way to create a unique field on an event is with the [Fingerprint Filter Plugin](https://www.elastic.co/guide/en/logstash/current/plugins-filters-fingerprint.html).
