Detailed Description

RollingFileAppender extends FileAppender to backup the log files when they reach a certain size.

Properties

Properties additional to FileAppender's properties:

MaxFileSize

This property specifies maximal size of output file. The value is in bytes. It is possible to use MB and KB suffixes to specify the value in megabytes or kilobytes instead.

MaxBackupIndex
This property limits the number of backup output files; e.g. how many log.1, log.2 etc. files will be kept.
