A logger is used a) by applications to generate log events or b) in a
configuration file to identify one or more appenders to route events to and to
filter events. The way you are using the word doesn't apply to either.
If I understand what you want you need some other application that tails the
log file being written and inspects the events as they arrive and then does
something with the events it sees. You could certainly use Log4j to write the
new messages, but you will have to write the app to tail the log and filter it.
Normally, one would go to each application and add a new appender to the
existing logger to send the specific events you are interested in to the new
destination.
