Akka SLF4J logback configuration and usage

Question

I have done the following steps to try and configure logging for my akka application:

• created an application.conf file and placed it in src/main/resources.

Answer 1

With this arrangement I can use an akka.event.Logging, no need to specify SLF4J instance.

(tested 13 Dec 2013)

I get console logging and logging to a file. To prove this is not built-in logger I changed to include %X{akkaTimestamp} as explained here:

http://doc.akka.io/docs/akka/snapshot/scala/logging.html

build.sbt

library dependencies: (Akka version 2.2.3)

...
"com.typesafe.akka" %% "akka-slf4j" % "2.2.3"
"ch.qos.logback" % "logback-classic" % "1.0.9"
...

src/main/resources/application.conf

akka {
  loggers = ["akka.event.slf4j.Slf4jLogger"]
  loglevel = "INFO"
}

src/main/resources/logback.xml

    
        System.out
        
            %X{akkaTimestamp} %-5level[%thread] %logger{0} - %msg%n
        
    

    
        log/akka.log
        false
        
            %date{yyyy-MM-dd} %X{akkaTimestamp} %-5level[%thread] %logger{1} - %msg%n
        
    

    

    
        
        
    

This arrangement works when I use an ActorLogging mixin and also create a Logging directly:

import akka.event.Logging

val log = Logging(context.system, classOf[NameOfYourActor])

log.info("good luck!")
