Hi,

I am using logstash 7.3.1 and trying to translate value inside the field after renaming. Basically I want to use translate plugin to translate the value inside the field and populate in same field or different field. If possible don`t want to use dictionary file and point it to file location. I dont know where am I going wrong as its not translating values.

filter {  
if [type] == "logs" {  
grok {  
match =\> { "message" =\> ["%{TIMESTAMP\_ISO8601:timestamp}%{DATA:loglevel}%{SYSLOGHOST:loglevel}%{DATA:source}%{GREEDYDATA:message}"] }  
}  
mutate {  
rename =\> { "[loglevel]" =\> "[syslog\_severity]" }  
}  
mutate {  
add\_field =\> ["received\_at", "%{@timestamp}"]  
add\_field =\> ["received\_from", "%{host}"]  
}

```
translate {
field => "loglevel"
destination => "syslog_severity"
 dictionary => {
  "TRACE" => "DEBUG"
  "DEBUG" => "DEBUG"
  "INFO" => "INFO"
  "WARN" => "WARN"
  "ERROR" => "ERROR"
  "FATAL" => "CRITICAL"
}
  remove_field => "loglevel"

```

}  
}  
}

The [loglevel] field will not exist when the translate filter executes because you have previously used mutate+rename to rename it.
