Wire listener logging

The wire listener can output informational messages, warnings, and errors as well as debug and trace information to a log.

The default logging mechanism for the wire listener is Logback. Logback is pre-configured and installed along with the JSON components. For more information on how to customize Logback, see http://logback.qos.ch/.

When you start the wire listener from the command line, you can specify the location of your log file and the amount of detail printed to the log by using the -logfile and -loglevel command-line arguments.

Important: If you have customized the Logback configuration or specified another logging framework, the settings for -loglevel and -logfile are ignored.
