Server Log Configuration

The logging can be controlled by the parameters specified in the preface_log_config.ini file. This file defines what will be logged to the console and what will be logged to the log file. The default log configuration is set to roll over monthly. The formatting options (i.e. [%-5p][%d] %m%n) in the Knomi logging configuration file are defined by the log4cplus library. See (Logging configuration example).
