Tal Liron commented on LOG4J2-476:
----------------------------------
What you say is possible only when users explicitly use EventLogger and
explicitly set the hostnaame. But this feature must be available for *all*
logged messages, even when using the alternate APIs (log4j 1.2, SLF4J), and it
should be automatic. Even if I'm running an old legacy library, I still need to
know from which node it originated. That's why I'm saying that it should be
handled at the appenders -- it is not the duty of the caller to explicitly set
it.

> Key: LOG4J2-476
> URL: https://issues.apache.org/jira/browse/LOG4J2-476
> Project: Log4j 2
> Issue Type: Improvement
> Components: Core
> Affects Versions: 2.0-beta9
> Reporter: Tal Liron
> Priority: Critical
>
> It's absolutely necessary to support this: when logging centrally, you *need*
> to know from where the log message arrived. I've marked the issue as
> critical, because log4j is not very useful without it in distributed
> environments. If you don't know where the log message came from, it's close
> to worthless.
> This applies at least to all classes that inherit from
> AbstractDatabaseAppender, but I think the solution should be more generic:
> developers might create their own appenders that would require this
> information. It can be handled, I think, in the same way as
> LogEvent.setIncludeLocation: allow all loggers to include this information if
> configured to do so.
