Do you know how to config logger properly, so it can rotate log files at midnight, and won't have logs on different days in same log file.
There is no TimeBasedRotation parameter. You can set either periodic rotation by setting RotationInterval to the number of seconds between rotations, or RotationTimePoint to the time point at which the rotation happens. The parameters are documented here.
