Log file rotation

[ThangHuuVu]

Is it configurable to always write logs to 1 specific file, and truncate it when it reaches file size limit?
I want to achieve something like:
Mainlog.log: The log file that will always be written to. It contains the latest log.
Log_001.log -> Log_009.log: The archived log files.
