Robert Schaft commented on LOG4J2-435:
--------------------------------------
Yes, the examples are complex. This was necessary to see, where the problems
are or might be. If you use complex test examples to test the logic, you can be
sure, that the simple ones work, too. If you use only simple use cases, it
might be unclear how to implement a little bit more complex test cases.
Filters are a good example: Because someone tested it only on simple
configurations, they are already hard to deal with if you combine two filters.
Perhaps I couldn't google the correct documentation. But it took me perhaps 15
minutes with a lot of testing to figure out, how I could send WARNings and
higher to STDERR and INFOs and lower (depending on the logger) to STDOUT. And
it is impossible to guess based on the xml elements.
Don't you think that xml configuration should be self explaining?
> 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.
