The first thing I see that is a problem is your tracing artifacts don't match your version of Akka. From your tree I can see you're using Akka 2.2.3:
[INFO] +- com.typesafe.akka:akka-kernel_2.10:jar:2.2.3:compile
but your tracing jar is for Akka 2.1
[INFO] +- com.typesafe.atmos:trace-akka-2.1.4:jar:1.3.1:compile
From here: http://resources.typesafe.com/docs/console/manual/getting-started.html#instrumentation
Your artifact for tracing Akka should be:
<dependency>
<groupId>com.typesafe.atmos</groupId>
<artifactId>trace-akka-2.2.1_2.10</artifactId>
<version>1.3.1</version>
</dependency>
And yes, in Akka 2.2 the logging configuration has changed: http://doc.akka.io/docs/akka/2.2.3/scala/logging.html
To use the console logger you need:
loggers = ["com.typesafe.atmos.trace.Slf4jTraceContextLogger"]
