In the Logabck Manual located here http://logback.qos.ch/manual/index.html, the link for "Chapter 9: JMX Configurator" is broken (http://logback.qos.ch/manual/jmxConfigurator.html).

However, the link pointed to the same subject in the right navigation bar seems good (http://logback.qos.ch/manual/jmxConfig.html).
