In at least one version of the manual, it gave instructions about copying a .conf file into rsyslog.d directoy to create a creston log file that you could print to with the error.notice function then ssh sudo tail -f /var/log/crestron/crestron.log and watch the log in realtime.
1. Move the 50-default.conf file from [VirtualControlHome]/samples/conf_files to the
/etc/rsyslog.d/ directory.
2. Issue sudo systemctl restart rsyslog.service to restart the system logging service.
