--------------------------------------
Summary: Compressing aged Rolled Files, keep last X file
uncompressed
Key: LOG4J2-1536
URL: https://issues.apache.org/jira/browse/LOG4J2-1536
Project: Log4j 2
Issue Type: New Feature
Components: Appenders
Reporter: Davide Steduto
{{RollingRandomAccessFile}} and {{RollingFileAppender}} currently support the
configuration to compress automatically files _every time_ it rolls and to
delete compressed file after Y days under provided conditions, but it
compresses at every rolling while we should have the possibility to keep the
last X rolled files uncompressed before it starts the compression.
Usually when we investigate, we do it for few days back, therefore those files
should remain uncompressed without the need to decompress the file that just
rolled (for instance: midnight is just passed).
I would add a new attribute named *max="5"* (keep last 5 logs uncompressed).
You choose the name. Default value = 0 (it always compresses).
{code:xml}
<RollingRandomAccessFile name="file" fileName="${baseDir}/app-trace.log"
filePattern="${baseDir}/app-trace-%d{yyyy-MM-dd}.log.gz" max="5"
immediateFlush="false" append="true">
...
</RollingRandomAccessFile>
{code}
Thank you,
Davide
