Hi there  
Here is my log line

[2020/02/11-20:22:06.643] !! Nom de classe de la BS : WXWXWX.Mtr.GpePayerEncaisser.Execution.Batchs.BS\_RequestExecution

I want to obtain a message like this  
datetime : 2020/02/11-20:22:06.643  
message : Nom de classe de la BS : WXWXWX.Mtr.GpePayerEncaisser.Execution.Batchs.BS\_RequestExecution to push it in elasticsearch.  
Here is my filter

filter {  
grok {  
match =\> { "message" =\> "(?\<REQ\_TIME\>%{YEAR}/%{MONTHNUM}/%{MONTHDAY} %{TIME})?%{GREEDYDATA:message}" }  
}   
}  
All i got is the line  
"message":["[2020/02/11-20:22:06.659] !! Date & heure : mar. 11 févr. 2020 20:22:06" twice.  
Thanks for any help

You can try this :

```
 filter {
        grok {
            match => {
                "message" => "\[%{GREEDYDATA:tmp}\]%{SPACE}!!%{GREEDYDATA:reste}"
            }
        }

        date {
            locale => "fr"
            match => ["tmp", "YYYY/MM/dd-HH:mm:ss.SSSSSS"]
            timezone => "Europe/Paris"
            target => "@timestamp"
            remove_field => "tmp" # Suppression du champs tmp.
        }
    }
```

Your REQ\_TIME pattern does not match the message. It does not match the square brackets and it separates date and time using space rather than a hyphen. You have made it optional (the trailing ?) so the entire value of [message] is consumed by %{GREEDYDATA:message}, which just adds a second copy of [message] to [message].

Do not make REQ\_TIME optional but also anchor it to start of line using ^
