Hello  
This is my json:

> {"serial\_number":"36307","time":"2017-11-20 08:10:40.340 +03:00","transaciton\_id":"","card\_hash":"","component":"READER","level":"DEBUG","message":"Request": SrvOpen: SrvOpenRequest: {"TgComName":"/dev/oti"}"}

I need translate my field serial\_number according with my yml file.

krotov@test:~$ cat /etc/logstash/dict.yml  
"36322": It worked!  
So. How i can translate this field?  
My config:

> input {  
> tcp {  
> port =\> 5044  
> host =\> '0.0.0.0'  
> }  
> }  
> filter {  
> date {  
> match =\> ["timestamp" , "dd/MMM/YYYY:HH:mm:ss Z"]  
> remove\_field =\> ["timestamp"]  
> }  
> json {  
> source =\> "message"  
> target =\> "css"  
> remove\_field =\> "message"  
> add\_field =\> {"sn" =\> "%{serial\_number}" } ###- this not work. in kibana saw sn: %{serial\_number}. ###  
> }  
> translate {  
> field =\> "serial\_number"  
> destination =\> "translate"  
> dictionary\_path =\> "/etc/logstash/dict.yml"  
> override =\> "true"  
> }  
> }  
> output {  
> elasticsearch {  
> hosts =\> "127.0.0.1:9200"  
> index =\> "mgt"  
> codec =\> rubydebug  
> document\_type =\> "%{[@metadata][type]}"

That indicates that your document doesn't have a `serial_number` field, which would also explain why the translate filter isn't working. Show a complete example document, e.g. by using a `stdout { codec => rubydebug }` output.

If your json document has a `serial_number` field, you are putting this under `css` as you have the `target` parameter set. This means that you would need to specify `%{[css][serial_number]}`.

[Here is an example](https://www.elastic.co/guide/en/logstash/6.0/event-dependent-configuration.html#sprintf) of how to address nested fields.
