Autodesk Support may ask for a log file to help to troubleshoot problems. The system log (syslog) file is a plain text file and can be copied with cp or filtered with grep.
This worked example for a Red Hat Enterprise 6 system collects all Moldflow logs in their own file /var/log/moldflow. This distribution of Linux uses the rsyslog daemon, which is configured through the /etc/rsyslog.conf file.
local4.* /var/log/moldflow
# service rsyslog restart
# /opt/Autodesk/moldflow/ami2016/sbin/reconfigure MFSYN_LOG_FACILITY=LOCAL4
# /etc/init.d/ami2016jm restart
