Verbose Mode Logging

There is no command-line argument for controlling the verbosity level for console messages. You can modify the type of messages that are appended to the logger by changing the rootLogger details so, for example, to suppress all INFO messages you can set WARN instead:

log4cplus.rootLogger=WARN, KatanaLogFile, KatanaConsoleOutput

Note:  To suppress messages in this way, you need to be change the existing log.conf file within the Katana installation directory, as there is no direct support for sourcing external log.conf files to customize the logging output.
