Subject [jira] [Commented] (LOG4J2-435) Feature request: auto-delete older log files
Date Mon, 30 Nov 2015 12:48:11 GMT

    [ https://issues.apache.org/jira/browse/LOG4J2-435?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15031726#comment-15031726

Robert Schaft commented on LOG4J2-435:
--------------------------------------

I really appreciate that you took the burden to implement this. And I don't want to be annoying.
I have just the feeling that the configuration is somehow not mathematically complete (allows
all combinations, that are technically possible).

You use nesting to implement the shortcut operator. Nice idea. But how can I use them in combination
with ifAll? The nesting is there already used for listing the conditions. How do I nest an
accumulator?

Could you provide more complicated examples?
# I want to keep only 100mb from all files that match a certain name debug*.log AND that are
older than 1 day.
# I want to keep only 100mb from all files that match a certain name debug*.log OR that are
older than 30 days.
# 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.

> 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.

> 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.
