The GMU logging is default written to gmu.log in the root directory. I would like to change the logfile name and location. There is an option --loggingProperties where you can specify a file for the logging properties. I made a file logging.config for this purpose, and filled it with the default values. Whatever I put in the file leads to an error. Is there an example of what has to be in the loggingProperties file to configure logfile name and location? And is it possible to configure logging directly from commandline?
