Log rotation provides an ability for a system administrator to systematically rotate and archive any log files produced by the system. Log rotation reduces the disk space requirement of an operating system. The feature uses the Linux log-rotate utility for log rotation. Log rotation rotates and compresses the log files either based on size and/or period. Rotated log files are stored locally or transferred to the remote destination using Trivial File Transfer Protocol (TFTP).

By default the log rotation feature rotates the log files daily. If the maximum file size exceeds 100 MB, log rotation is also triggered. Whichever condition occurs first (period or size) triggers the log rotation.
