[jira] [Commented] (LOG4J2-3389) Log42j: Provide the capability to Rollover all appenders in an application on Shutdown

["Ralph Goers (Jira)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/LOG4J2-3389?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17494922#comment-17494922 ] 

Ralph Goers commented on LOG4J2-3389:
-------------------------------------

I would imagine it would be simple to write an OnShutdownRolloverPolicy that registers itself as a shutdown listener. However, it will only be triggered on a normal shutdown. It would not be possible to rollover when the JVM or server crashes.

>          Components: Appenders, Configuration
>    Affects Versions: 2.17.1
>         Environment: All, provide the feature as an implementation that can be defined in the Log4j2 Configuration

>            Priority: Major

>             Fix For: 2.18.0

> I have seen many issues raised in StackOverflow for different variations of finding  a good solution to rolling over of all appenders in an application on Shutdown. But no clear and best solution emerges.
> Hence raising this issue which we in our organisation also have  a great and urgent Need for.
> What we need is:
> A Rollover strategy that we can include in all appenders in the Log4j2 Configuration, in the Appender definition to properly rollover the associated log files on Shutdown.
> The full rollover functionality needs to be defined fully in the Configuration only and no need for Java Code to be written to call the LogManager.Shutdown() method.
> This feature would be a tremendous boost particularly managing log files associated with multiple pods in Kubernetes deployed applications.
