DailyRollingFileAppender extends FileAppender so that the underlying file is rolled over at a user chosen frequency.
Properties additional to FileAppender's properties:
Schedule
This property specifies rollover schedule. The possible values are MONTHLY
, WEEKLY
, DAILY
, TWICE_DAILY
, HOURLY
and MINUTELY
.
MaxBackupIndex
This property limits how many backup files are kept per single logging period; e.g. how many log.2009-11-07.1
, log.2009-11-07.2
etc. files are kept.
