What is the logback log clean-up mechanism?

Logback is a Java logging framework with a log cleanup mechanism achieved by configuring a RollingFileAppender.

The RollingFileAppender can roll log files according to a certain strategy to clean up expired log files. Common rolling strategies include time-based rolling and size-based rolling.

A time-based rolling strategy can be used to clean up log files based on their age. The common configuration is to set a maximum retention period; when the creation time of a log file exceeds this period, it will be deleted.

The size-based rolling strategy clears log files based on their size, typically by setting a maximum file size. When a log file exceeds this size, it will be automatically cleaned up.

In addition to the scroll strategy, you can also configure the number of log files to keep, meaning how many of the latest log files will be retained and any exceeding that number will be deleted.

By configuring parameters such as rolling strategy, retention time, and retention count of RollingFileAppender, you can implement Logback’s log cleaning mechanism.
