The filter suggestion is a bit overkill for what you need.
What is happening is that you are assigning a DEBUG threshold to all
logging requests to loggers starting with "com.dsn.loadlink", all
other loggers have a threshold of WARN. You are also attaching a
ConsoleAppender to the root logger and a RollingFileAppender to
"com.dsn.loadlink", but that is an independent action from setting the
thresholds.
So if you make a logging request on "com.dsn.loadlink" or a child
logger, it is evaluated against the nearest specified threshold and if
that is satisfied, then it is processed by all appenders attached in
the hierarchy (unless additivity is set to false which will prevent
appenders attached to parent loggers from seeing the event). You can
set a threshold on the appender which is independent of the threshold
on the logger.
Unless you have a specific need to separate the appenders, I would
attach them both to root, but set a threshold on the ConsoleAppender.
