Akka Logging outside Actor

Question

I have an Akka Actor that makes a call to MyObject.foo(). MyObject is not an Actor. How do I setup Logging in it? With an Actor it\'s simple, because

Actually I would redirect Akka logging to slf4j and use this API directly in all unrelated classes. First add this to your configuration:

akka {
    event-handlers = ["akka.event.slf4j.Slf4jEventHandler"]
    loglevel = "DEBUG"
}

Then choose some SLF4J implementation, I suggest logback. In your actors continue using ActorLogging trait. In other classes simply rely on SLF4J API - or even better - try out slf4s facade around SLF4J.

Tip: try out the following logging pattern in Logback:

%d{HH:mm:ss.SSS} | %-5level | %thread | %X{akkaSource} | %logger{1} | %m%n%rEx

The %X{akkaSource} will print actor path when available (just like standard logging).
