Hi Dirk,

Sorry for the late reply.

I believe that logback's internal status reporting is one of its strong points. 
Basically, all logback modules (logback-core, logback-classic and 
logback-access) revolve around a context, a LoggerContext in case of 
logback-classic. All problems encountered during the lifetime of the context are 
reported through status messages which are added to a StatusManager. Each 
context has its own separate StatusManager.

Thus, whenever you wish to print the internal status of a context, you call
StatusPrinter.print(context). In logback-classic, the exact steps would be

  LoggerContext lc = (LoggerContext) LoggerFactory.getILoggerFactory();

For more complete examples see "Chapter 2 - Architecture" [1] section entitled 
"Configuration" and especially the MyAppWithConfigFile class [2].

I hope this helps,
