Ralph Goers commented on LOG4J2-435:
------------------------------------
The only difference with what we are doing in general is that you would specify:
{code}
<Delete baseDir="${sys:base}" maxDepth="2">
<ScriptCondition>
<Script language="groovy">groovy script goes here</Script>
</ScriptCondition>
</Delete>
{code}
{code}
<Delete baseDir="${sys:base}" maxDepth="2">
<ScriptCondition>
<ScriptFile path="path/to/my/script.groovy">
</ScriptCondition>
</Delete>
{code}
or
{code}
<Scripts>
<ScriptFile path="path/to/my/script.groovy" name="deleteScript"
isWatched="true"/>
</Scripts>
<Delete baseDir="${sys:base}" maxDepth="2">
<ScriptCondition>
<ScriptRef ref="deleteScript">
</ScriptCondition>
</Delete>
{code}
Note that the Script, ScriptFile and Scripts elements are already implemented.
The only thing Remko needs to do is implement the ScriptCondition element. The
ScriptCondition can be implemented to call the script for each file and return
true or false as to whether it should be deleted, or it could be implemented to
pass the script a list of all the files and expect the script to return those
that should be deleted.
> Feature request: auto-delete older log files
> ---------------------------------------------
>
> Key: LOG4J2-435
> URL: https://issues.apache.org/jira/browse/LOG4J2-435
> Project: Log4j 2
> Issue Type: Improvement
> Reporter: Arkin Yetis
> Assignee: Remko Popma
> Labels: Rollover
> Fix For: 2.5
>
> Attachments: LimitingRolloverStrategy.java, SizeParser.java
>
>
> Original description:
> {quote}
> 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.
> {quote}
> ----
> 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.
