Hi Remko,

Thanks for your suggestion, I extends the ExtendedLoggerWrapper and override
logMessage(String fqcn, Level level, Marker marker, Message message,
Throwable t) to add my specific marker, it works. But I still wonder if it's
possible to enable user to add marker to logger through API directly, it
could be a feature implemented in the feature.

Best regards.

The log4j API does not provide a way to "set" a marker that will be emitted
on all events produced by that logger. 

However, one idea is to generate a logger wrapper and write the above logic
in the wrapper. Log4j provides a tool to generate logger wrappers for custom
log levels. This will give a good starting point. 

Let me know if you have questions. 
Remko

of using marker is not so convenient if I want to add same marker to
multiple log records, so I require to add marker to a logger directly, then
all log records using this logger will have this marker automatically, do we
have this feature now in log4j2.5? or is there any workaround to achieve
this?
