Please post full examples when trying to debug such things ;-) I have to guess that you didn’t configure the actual logger. Yet you did configure the logging filter, so things will try to use the loggers config, but there is none, so empty.

When I run the program, I see only one log line printed: QuickStart-akka.actor.default-dispatcher-2] INFO akka.event.slf4j. Slf4jLogger - Slf4jLogger started I expect to see more, what am I missing?
