Volkan - Do you not support the MapMessage? That is the standard way to handle this and is what Log4j Audit does. It uses an AuditMessage that extends MapMessage. In fact, I should be able to construct a template for AuditMessage to use with JsonTemplateLayout in Log4j-Audit. If I cannot then there is a problem. I should point out that with auditing I might have a hundred or more potential keys depending on how many audit events I have defined. I would not want to create a layout that explicitly specifies them all. But for a MapMessage I don’t see why I should have to.
