LoggingBus

trait LoggingBus extends ActorEventBus

This trait brings log level handling to the EventStream: it reads the log levels for the initial logging (StandardOutLogger) and the loggers & level for after-init logging, possibly keeping the StandardOutLogger enabled if it is part of the configured loggers. All configured loggers are treated as system services and managed by this trait, i.e. subscribed/unsubscribed in response to changes of LoggingBus.logLevel.

    Change log level: default loggers (i.e. from configuration file) are subscribed/unsubscribed as necessary so that they listen to all levels which are at least as severe as the given one. See object Logging for more information.

    NOTE: if the StandardOutLogger is configured also as normal logger, it will not participate in the automatic management of log level subscriptions!
