Hello,

I would like to make services translation like this:  
21/tcp =\> ftp  
80/tcp =\> http

But the translation doesn't work.

So, my services.yaml file is like this :  
"1/tcp": "tcpmux"  
"1/udp": "tcpmux"  
"5/tcp": "rje"  
"5/udp": "rje"  
"7/tcp": "echo"  
"7/udp": "echo"  
"9/tcp": "discard "  
"9/udp": "discard"  
"11/tcp": "systat"  
"11/udp": "systat"  
"13/tcp": "daytime  
.....

And my Logstash Configuration

```
                    filter {
                            mutate {

                            add_field => {"application_name" => "%{[netflow][l4_dst_port]}/%{protocol_name}"}
                            convert => {"application_name" => "string"}
                            }

                            translate {
                            field => "application_name"
                            destination => "application_name"
                            dictionary_path => "/opt/logstash/conf/services.yaml"
                            }

                    }
```

If you output your events to stdout using the stdout output plugin and the rubydebug codec, what do they look like?

It's resolved now :

filter {

```
                            mutate {
                                            add_field => {"app_name" => "%{[netflow][l4_dst_port]}/%{protocol_name}"}
                                    }
                    
                    
                            translate {
                            field => "app_name"
                            destination => "application_name"
                            dictionary_path => "/opt/logstash/conf/services.yaml"
                           
                            }

```

And I changed my services.yml file because the value doesn't contains =\> "

"1/tcp": "tcpmux" move to "1/tcp": tcpmux  
"1/udp": "tcpmux" move to "1/udp": tcpmux

So it was, my bad configuration in my yaml file
