    Main entry point for Akka logging: log levels and message types (aka channels) defined for the main transport medium, the main event bus.

    Main entry point for Akka logging: log levels and message types (aka channels) defined for the main transport medium, the main event bus. The recommended use is to obtain an implementation of the Logging trait with suitable and efficient methods for generating log events:

    
val log = Logging(<bus>, <source object>)
...
log.info("hello world!")

    The source object is used in two fashions: its Class[_] will be part of all log events produced by this logger, plus a string representation is generated which may contain per-instance information, see apply or create below.

    Loggers are attached to the level-specific channels Error, Warning, Info and Debug as appropriate for the configured (or set) log level. If you want to implement your own, make sure to handle these four event types plus the InitializeLogger message which is sent before actually attaching it to the logging bus.

    Logging is configured by setting (some of) the following:

    
akka {
  loggers = ["akka.slf4j.Slf4jLogger"] # for example
  loglevel = "INFO"        # used when normal logging ("loggers") has been started
  stdout-loglevel = "WARN" # used during application start-up until normal logging is available
}

StandardOutLogger

class StandardOutLogger extends InternalActorRef with MinimalActorRef with StdOutLogger

Actor-less logging implementation for synchronous logging to standard output. This logger is always attached first in order to be able to log failures during application start-up, even before normal logging is started. Its log level can be defined by configuration setting akka.stdout-loglevel.

  1. def !(message: Any)(implicit sender: ActorRef = Actor.noSender): Unit

    Sends a one-way asynchronous message.

    Sends a one-way asynchronous message. E.g. fire-and-forget semantics.

    If invoked from within an actor then the actor reference is implicitly passed on as the implicit 'sender' argument.

    This actor 'sender' reference is then available in the receiving actor in the 'sender()' member variable, if invoked from within an Actor. If not then no sender is available.

    Obtain ActorRef by possibly traversing the actor tree or looking it up at some provider-specific location. This method shall return the end result, i.e. not only the next step in the look-up; this will typically involve recursive invocation.
