Firstly, the level name to use is
DEBUG. Let’s assume for a minute that
DEBUG is actually valid, as it makes the following explanation make a bit more sense…
Handler specific properties section, you’re setting the logging level for those handlers to
DEBUG. This means the handlers will handle any log messages with the
DEBUG level or higher. It doesn’t necessarily mean any
DEBUG messages are actually getting passed to the handlers.
Facility specific properties section, you’re setting the logging level for a few explicitly-named loggers to
DEBUG. For those loggers, anything at level
DEBUG or above will get passed to the handlers.
The default logging level is
INFO, and apart from the loggers mentioned in the
Facility specific properties section, all loggers will have that level.
If you want to see all
FINE messages, add this:
.level = FINE
However, this will generate a vast quantity of log messages. It’s probably more useful to set the logging level for your code:
your.package.level = FINE
1catalina.org.apache.juli.FileHandler.level = FINE
and also gives you examples of setting additional logging levels:
# For example, set the com.xyz.foo logger to only log SEVERE
#org.apache.catalina.startup.ContextConfig.level = FINE
#org.apache.catalina.startup.HostConfig.level = FINE
#org.apache.catalina.session.ManagerBase.level = FINE
