Hi,  
I want to change the @timestamp to the timestamp out of event.original or message. I don't know what I do wrong.  
right now the @timestamp is the time where the filebeat logfile ist importet thru logstash into elasticsearch.

@timestamp: Feb 15, 2023 @ 10:36:22.692  
event.original: 06-02-2023 13:10:58:034, INFO , ....  
message: 06-02-2023 13:10:58:034, INFO , ...

in my sample.conf I try it with:  
filter {  
date {  
match =\> ["Event Time", "dd-MM-YYYY HH:mm:ss:SSS"]  
target =\> "@timestamp"  
}  
}

Thank you

Are you using grok or dissect to parse the [Event Time] field from [message]? What does your configuration look like for that?

I think that's one of my problems or challenges. I entered Grok, but I suspect that this is where the error lies. I already apologize for my ignorance.

filter {  
grok {  
match =\> ["message", "%{SYSLOGBASE} %{GREEDYDATA:new\_message}"]  
}  
date {  
match =\> ["Event Time", "dd-MM-YYYY HH:mm:ss:SSS"]  
target =\> "@timestamp"  
}  
}

This is not assigned, should be `%{SYSLOGBASE:[@metadata][EventTime]}`

```auto
date {
  match => ["[@metadata][EventTime]", "dd-MM-YYYY HH:mm:ss:SSS" ]
  target => "@timestamp"
}

```

Also, the message format is not going to match SYSLOGBASE. That expects %{MONTH} +%{MONTHDAY} %{TIME}, whereas the [message] field appears to match ISO8601.

Thank you for the info, but what or how do I have to enter it then?

I have now updated my Filter, but in Elasticsearch the cells are empty.

filter {  
grok {  
match =\> { "message" =\> %{DATESTAMP:[@metadata][EventTime]},%{SPACE}%{LOGLEVEL:loglevel, %{GREEDYDATA:message}"}  
}  
date {  
match =\> ["timestamp", "dd-MM-yyyy HH:mm:ss:SSS"]  
target =\> "@timestamp"  
}  
}

[@metadata][EventTime] in _date_:

```auto
filter {
grok {
  match => { "message" => "%{DATESTAMP:[@metadata][EventTime]},%{SPACE}%{LOGLEVEL:loglevel, %{GREEDYDATA:message}" }
}
date {
match => ["[@metadata][EventTime]", "dd-MM-yyyy HH:mm:ss:SSS" ]
