Robert Schaft commented on LOG4J2-435:
--------------------------------------
I think you got confused because of some {{<If>}} {{<And>}} and {{<Or>}}
elements. The names were chosen only to give a clear hint to a (boolean)
logically thinking users.
You could also name them "trigger" (for OR-combinations) or "filter" (for
AND-combinations). But it is the same stuff.
Only because a configuration might be replaceable with a script, it doesn't
mean that it is a (Turing complete) programming language.
If you start that way, you could replace every configuration by a script (e.g.
a script that decides if an event should be logged, a script that decides if a
file should be rolled over). But we don't want to go there. Remko and me are
just trying to figure out, how a broadly useable configuration could look like.
> 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.
