Hi,
I've updated the TimeAndSizeRollingAppender that I originally contributed to
the Log4J project back in September 2007. Whilst this isn't an integration
with the (much cooler and more flexible) Log4J Extras, it does seem to be
useful and as far as I know is being used in a handful of production
environments.
This appender has the following features:
* Rolls by time like the DailyRollingFileAppender.
* Rolls files by size like the RollingFileAppender.
* Deletes older backup files like the RollingFileAppender, but backup
files are deleted asynchronously in a single daemon thread.
* Compresses backup files asynchronously using either ZIP or GZIP, also
in a single daemon thread.
* Configuration is very straightforward - there's only an appender to
configure.
Asynchronicity ensures that housekeeping the logs doesn't interfere unduly with
application threads. However, this puts the onus on the developer to make sure
the logging system is stopped cleanly on application shutdown.
Javadoc, featuring a sample configuration, and JAR download are freely
available, distributed as per the rest of Log4J under the Apache 2.0 license.
HTH,
Simon
