What does your data look like? What are you trying to achieve? Showing an example is often much better than trying to describe the problem?

This doesn't really make much sense as it will just copy the message field into a `selectedMessage` field. Please explain what you are trying to do with your data, not how.

Why do you need to use a ruby filter? What do you want to do with it?

hi christian\_Dahlqvist,  
my log data is different patterns  
grok {  
match =\> { "message" =\> "%{TIMESTAMP\_ISO8601:Date} %{TIMESTAMP\_ISO8601:Actual\_Date} (?[\w.|-]+) \<%{LOGLEVEL:Severity}\> (?[\w:|\_]+): %{GREEDYDATA:Detalis}"}

}  
Above filter i used after "%{GREEDYDATA:Detalis}" this data is i need to send ruby filter and run regux operation.  
i used ruby path and script\_params to perform .  
how can i do this ?

You should be able to get to all fields of the event through the `event` that is passed to the filter method. I would expect the filter to be initialised based on the script\_params once and not per event.

Error:-  
Could not process event: Direct event field references (i.e. event['field']) have been disabled in favor of using event get and set methods (e.g. event.get('field')). Please consult the Logstash 5.0 breaking changes documentation for more details.
