>                 Key: LOG4J2-770
>                 URL: https://issues.apache.org/jira/browse/LOG4J2-770
>             Project: Log4j 2
>          Issue Type: New Feature
>          Components: API, Core
>            Reporter: Krzysztof Szewczyk

> It would be useful to add method addOnLogging or similar that would be enable the addition action during logging.
> In my work copy I did something like that:
> - I created:
>   >>public interface OnLogging{ public void onLogging(Level level, Object message, Throwable ex); }<<
> - I added to interface Logger method:
>   >>public void addOnLogging(OnLogging ol);<<
> - in Logger implementations I added:
>   >>private List<OnLogging> onLoggingList;<<,
>   implemented:
>   >>public addOnLogging(OnLogging ol){ onLoggingList.add(ol); }<<
>   and on method:
>   >>public void logMessage(final String fqcn, final Level level, final Marker marker, final Message msg, final Throwable throwable)<<
>    I added:
>   >>for(OnLogging ol : onLoggingList) { ol.onLogging(level, msg, t); }<<
> I needed it because I wanted to bind logs with my gui - on logging action I update some control to give user some information.
> I hope that you will consider it a useful feature
