-----------------------------------
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.
