Subject [jira] [Commented] (LOG4J2-435) Feature request: auto-delete older log files
Date Thu, 03 Dec 2015 16:26:11 GMT

    [ https://issues.apache.org/jira/browse/LOG4J2-435?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15038030#comment-15038030
] 

Paul Benedict commented on LOG4J2-435:
--------------------------------------

[~mikaelstaldal] I amended my post to say that JUEL can be used outside the container. You
just need the right implementation jar.

[~ralphgoers] It's unnecessarily verbose to use {{ScriptCondition}}. You already have tags
that have an implied condition; just attach it to that. If it's about time frames, then go
with {{ScriptCondition}} for 2.0; perhaps in 3.0 you can move to specifying the expression
as an attribute. Go for concise if you can.

> 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.
