May somebody help me to solve the following problem?

My index gets written into elasticsearch but the field host.name is not changed according the predefined dictionary.

Data gets ingested from a metricbeat v7.3.

```
input {
    pipeline { address => "metricbeat-ais" }
}

filter {
	translate {
		field => "host.name"
		destination => "host.name"
        override => "true"
        dictionary => {
            "host-001" => "COM"
            "host-002" => "AMS"
		    "host-003" => "WEB"
            "host-004" => "SQL"
        }
	}
}

output {
    ...
    }
}
```

Are you sure it has a period in the field name, or is it a nested field that you would refer to as [host][name] in logstash?

I rely on ECS.  
Your feedback solved my problem:

```
field => "[host][name]"
destination => "[host][name]"

```

Thanks Badger!
