Log rotation is a method used to manage the size of log files on servers. When a log file reaches a specified limit, usually based on its size or number of records, the corresponding application will rename the file, create a new one with the original name, and continue logging events in the new file.
Log rotation is crucial because it prevents log files from consuming all available disk space, ensures the smooth operation of the system, and allows access to older log data.
