---------------------------------------------------------------
I advise not to construct boolean logic out of XML tags. Why? Because whatever
you think is acceptable someone will want more. Someone always can come up with
a more complex condition than you envisioned. Instead, provide a means to
specify class that Log4J2 will instantiate; the class will implement some new
SPI that simply evaluates for a boolean.
Example:
{code}
public interface FilterCondition {
public boolean evaluate(SomeContext context);
}
{code}

> 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.
