This is a good idea. If you can provide a patch that would be great too!

Layout by Reference?

[jeremy]

It would be nice if config supported by reference layout definition
(LayoutRef / Layout ref="XX") similar to the way we can use
AppenderRef/Appender ref="XX"

Why? Because often a single layout configuration is used between several
appenders (like in a failover definition) and copy-pasta configuration can
lead to unintended behavior and lost data.

Didn't see any tickets on this in jira, would you like me to open one?

thanks,

Re: rolling daily logger

[Daniel Widdis]

This is not yet a feature of Log4J2.  There are a few JIRA tickets open 
for this feature request that you may wish to track:


https://issues.apache.org/jira/browse/LOG4J2-524

https://issues.apache.org/jira/browse/LOG4J2-435

In the meantime, you can set up an external script to clean up old files 
based on filename (datestamp) or last access date.

rolling daily logger

[Mark Lybarger]

i'm using log4j2 for some of the filters (level and dynamic).  I want my
logs to roll based on size (this makes it easy to open in vim), but also by
date (this helps organize them and I only need 1 week of logs).


here's my current configuraiton. i'm un sure how to specify a rollover
strategy that keeps 7 days worth of files with a size based triggering
policy.


any help would be most appreciated.


thanks,

Re: Migrating from log4j 1x to 2x

[Jeff Snow]

I believe what you want to do is this (from the Log4j2 docs):

  The following XML fragment defines policies that rollover the log when the 
JVM starts, when the log size reaches twenty megabytes, and when the current 
date no longer matches the log’s start date.

Subject: RE: Migrating from log4j 1x to 2x

I want to implement log4j so that it creates a new file every day and if in a 
day a file grows more than 10 MB then it rolls over same day file into multiple 
files.

I used TimeBased and SizeBased trigger policy




interval = 24 hours and size 10MB.

but i am not able to achieve the results.

logs are still written to same file. only thing what it did is it created only 
one back up file and whenever new 10MB of logs are written it moved those to 
backup file.

I am not seeing multiple files.

I am attaching my log4j2.xml

Could you guys please take a look and let me know what am i doing wrong. what 
can i change to satisfy my requirement.

Regards,
Mangat Rai
