Subject [jira] [Commented] (LOG4J2-435) Feature request: auto-delete older log files
Date Mon, 30 Nov 2015 12:06:11 GMT

    [ https://issues.apache.org/jira/browse/LOG4J2-435?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15031697#comment-15031697
] 

Remko Popma commented on LOG4J2-435:
------------------------------------

Ordering is supported. Please take a look at the Appenders manual page in master. The Delete
element takes a PathSorter element (any plugin that implements the PathSorter interface).
Each Delete element can only have one sorter, but DefaultRolloverStrategy accepts multiple
Delete elements. When omitted, the default is to sort most recent files first, and if they
have the same lastModified time, then sort by path in reverse typographical order. 

There's no restriction on the number of filters. You can nest multiple conditions in a parent
condition. The nested conditions are only considered if the parent condition accepts.

> DefaultRolloverStrategy max attribute only applies if you have a %i in the file pattern.
This request is to enhance DefaultRolloverStrategy or another appropriate component to allow
a max number of files limit to apply across days/months/years when a filePattern includes
a date pattern.

> One of the most requested features is to add the ability to Log4j to "clean up" older
log files.  This usually means deleting these files, although it could also mean moving them
to a different location, or some combination of these. 
> Users have different requirements for selecting the files to clean up. A common request
is the ability to keep the last X number of log files. This works well if rollover is only
date based but may give undesired results with size based rollover. 
> Another factor to consider is that the directory containing the log files may contain
the log files for multiple appenders, or even files unrelated to logging.
