How to convert "on"/"off" text into boolean with Logstash?


#1

I have a field, that contains either "" (empty string) or "on".

I want to convert that field into an boolean, which treats "" (empty string) as false and "on" as true.

As mentioned with the documentation, the mutate convert filter treats:

  • "true", "t", "yes", "y", and "1" as true
  • "false", "f", "no", "n", and "0" as false
  • empty strings as false

Is there any way to configure mutate convert, that it also convert "on" into true? Maybe just for that particular mutate filter?
