If you see that FusionReactor is not persisting logs to the disk, this indicates there may be a permissions issue in the FusionReactor instance directory.

You should ensure that FusionReactor can create log files you must ensure that within the FusionReactor instance directory, typically located at {FusionReactor Directory}/instance/{Instane Name}, the user running the application server can read and write to the log and archive directory.

It is generally advised that the user can read and write to the entire FusionReactor directory.
