By default, the mono output is dumped to /dev/null (Linux) or nowhere (Windows). If you want to see the log, there are a couple approaches. You can either use nlog to view the log that HG generates, you can launch HG via command line (stop the service, run HG manually from command line, or you can modify the /usr/local/bin/HomeGenie/startup.sh file to redirect the output of the mono command to a file rather than /dev/null. If you are running Windows, the concept is the same but the commands are a little different.
