             Summary: Provide shorter and more intuitive way to switch on Log4j internal debug logging
                 Key: LOG4J2-1813
                 URL: https://issues.apache.org/jira/browse/LOG4J2-1813
             Project: Log4j 2
          Issue Type: Improvement
          Components: Configurators
    Affects Versions: 2.8
            Reporter: Remko Popma
            Assignee: Remko Popma
             Fix For: 2.8.1


People find it difficult to troubleshoot Log4j 2 configuration issues. Many people don't know what the "status" attribute is for at the beginning of the configuration:

{code}
<Configuration status="warn"> ...
{code}

In addition, the above setting does not take effect until the configuration file is found. If users have trouble making Log4j 2 find their configuration file, the above does not help.

In such cases, users can enable internal status logging by setting system property {{org.apache.logging.log4j.simplelog.StatusLogger.level}} to {{TRACE}}.

This is problematic because:
* It is not well-known (documented in the FAQ and on the configuration page but many people don't know about this feature)
* The name is a bit... lengthy :-) 
* Apparently people don't intuitively grasp that "status logging" means the internal log4j 2 debug logging facility.
* It is confusing that there are two phases (before config file found and after), and the status logger level can be different and needs to be specified separately

I propose we add a short, intuitive system property that results in _all_ internal Log4j 2 status logging to be printed to the console. When set, this property should even override the configuration status attribute in my opinion.

Something like {{-Dlog4j2.debug}} would be good, but I'm open to any suggestions.
