[jira] [Commented] (LOG4J2-1171) LoggerContext names are cryptic

["Remko Popma (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/LOG4J2-1171?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14970428#comment-14970428 ] 

Remko Popma commented on LOG4J2-1171:
-------------------------------------

Would it be okay to add a method to the ContextSelector interface? 

Something like
{code}
LoggerContext getContext(String fqcn, ClassLoader loader, boolean currentContext, URI configLocation, String name);
// where name is passed to the LoggerContext constructor
{code}

One alternative is to set/modify the LoggerContext name after it is constructed. (It is currently a final field without a setter.)

Another alternative would be to create a new interface that subclasses ContextSelector and add the above new method to this interface. {{Log4jContextFactory.getContext}} would check the type of the selector and cast to the new interface to call the new method where possible.

> LoggerContext names currently look like "5e90b76c", or "AsyncContext@5e90b76c". Originally the LoggerContext name was ClassLoader.toString(), but this had issues for very long multi-line classloader descriptions (LOG4J2-666).
> The problem with the current naming is that a web container with multiple web applications deployed will not be able to determine which of the Log4j2 JMX MBeans maps to which web application. Similarly, debug-level status messages at startup cannot be mapped to the correct web app.
> The place to address this is probably {{Log4jContextFactory.getContext(String fqcn, ClassLoader loader, Object externalContext, boolean currentContext, URI configLocation, String name)}}. 
> The specified name is currently ignored.
