We are using an external library, which is registering messages as error messages. These messages cause alerts in our alert system, which should not. As a result, I would like to change the level of these messages at runtime (I do not have access to the source) to a lower level, such as a warning. I thought about using a filter, but I would still like to record those messages, but at a lower level (for example, the error becomes a warning).
I thought about creating a specific appender, but it seems that it is difficult to implement again the creation of registration messages to republish them at a lower registration level.
