Gary D. Gregory commented on LOG4J2-3340:
-----------------------------------------
Great explanation [~rgoers] , TY.
The bottom line here IMO, is that we need better docs:
I added some internal Javadoc for the StatusLogger
This is now the logger level is set:
# If the property
["log4j2.debug"|eclipse-javadoc:%E2%98%82=log4j-api/src%5C/main%5C/java=/optional=/true=/=/maven.pomderived=/true=/%3Corg.apache.logging.log4j.util%7BConstants.java%E2%98%83Constants%5ELOG4J2_DEBUG]
is {{{}"true"{}}}, then use
{{{}[Level.TRACE|eclipse-javadoc:%E2%98%82=log4j-api/src%5C/main%5C/java=/optional=/true=/=/maven.pomderived=/true=/%3Corg.apache.logging.log4j.status%7BStatusLogger.java%E2%98%83StatusLogger~StatusLogger~QString;~QMessageFactory;%E2%98%82Level%E2%98%82TRACE]{}}},
otherwise,
# Use
{{[Level.ERROR|eclipse-javadoc:%E2%98%82=log4j-api/src%5C/main%5C/java=/optional=/true=/=/maven.pomderived=/true=/%3Corg.apache.logging.log4j.status%7BStatusLogger.java%E2%98%83StatusLogger~StatusLogger~QString;~QMessageFactory;%E2%98%82Level%E2%98%82ERROR]}}
This is now the listener level is set:
# If the property
["log4j2.StatusLogger.level"|eclipse-javadoc:%E2%98%82=log4j-api/src%5C/main%5C/java=/optional=/true=/=/maven.pomderived=/true=/%3Corg.apache.logging.log4j.status%7BStatusLogger.java%E2%98%83StatusLogger%5EDEFAULT_STATUS_LISTENER_LEVEL]
is set, then use {_}it{_}, otherwise,
# Use
{{[Level.WARN|eclipse-javadoc:%E2%98%82=log4j-api/src%5C/main%5C/java=/optional=/true=/=/maven.pomderived=/true=/%3Corg.apache.logging.log4j.status%7BStatusLogger.java%E2%98%83StatusLogger~StatusLogger~QString;~QMessageFactory;%E2%98%82Level%E2%98%82WARN]}}
What this means is that you need the StatusLogger level set to a level that
will allow the listeners in the StatusLogger to kick in.

> URL: https://issues.apache.org/jira/browse/LOG4J2-3340
> Project: Log4j 2
> Issue Type: Bug
> Reporter: Michael Vorburger
> Assignee: Gary D. Gregory
> Priority: Major
> Fix For: 2.17.2
>
>
> I would like to see the warn log from {{LogManager}} re. which implementation
> it picked, if multiple.
> I would like to be able to do this without a system property but using a
> properties file on the classpath.
> StatusLogger's JavaDoc (currently) says that "This can be overridden via a
> system property named #DEFAULT_STATUS_LISTENER_LEVEL and will work with any
> Log4j provider.", where DEFAULT_STATUS_LISTENER_LEVEL is
> "log4j2.StatusLogger.level".
> However that currently doesn't seem to quite work as advertised. (If you
> think it does, please suggest how.) I can see some stuff in StatusLogger
> related to its default log level been (only?) for StatusListener and
> StatusData? This seems confusing.
> I'll raise a PR with a proposed simple fix for this for your review.
