How to change akka Actors logLevel at runtime with application.conf

Question

How can I set application.conf to be able to change akka logLevel at runtime? Are there any properties I can set? I'm using slf4j and logback as backend. I've just set my logback.xml:

<configuration debug="true" scan="true" scanPeriod="10 seconds">
    .....
</configuration

Enable DEBUG in your application.conf and rely entirely on logback to filter statements out based on log level.

Make sure to enable the Slf4jLoggingFilter in your config to not get a performance hit when DEBUG in logback is not enabled:

logging-filter = "akka.event.slf4j.Slf4jLoggingFilter"
