On an local atom, a notify shape with the option "Enable User Log" enabled generates a logfile with the name format <Process Name>.yyyy_MM_dd.log. This user event log file is located in the same logs folder of the atom installation directory that contains the container log files.
Log files of the local atom can be download via Atom Management->Atom->Information->Log Files. I have noticed that these downloads do contain the container logs but do not contain the user logs. Is this a bug?
