------------------------------------
Haha, sorry about that. :-)
Looking at your 3rd case "I want to keep only the last 10 files but at most
100mb from all files that match a certain name debug*.log AND that are older
than 1 day", it does not have any OR conditions, only AND conditions ("but" in
propositional logic is AND, not OR). So this would be:
{code}
int fileCounter = 0;
long totalFileSize = 0L;
if (fileName.matches("debug.*\\.log") && now() - modificationTime <= 1 * DAY) {
totalFileSize += file.size();
if (totalFileSize > 100*MB) {
if (++fileCounter > 10) {
delete(file);
}
}
}
{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.
