[jboss-jira] [JBoss JIRA] Closed: (JBAS-6205) Make server.log logging level configurable via system property

[Brian Stansberry (JIRA)]

     [ https://jira.jboss.org/jira/browse/JBAS-6205?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Brian Stansberry closed JBAS-6205.
----------------------------------

    Resolution: Done


The server.log threshold can be controlled as follows:

./run.sh -Djboss.server.log.threshold=WARN

The default if the system property is not set is currently DEBUG.  This can be changed via a new mbean attribute added to conf/jboss-service.xml:

<mbean code="org.jboss.logging.Log4jService"
      name="jboss.system:type=Log4jService,service=Logging"
	  xmbean-dd="resource:xmdesc/Log4jService-xmbean.xml">
      <attribute name="ConfigurationURL">resource:jboss-log4j.xml</attribute>
      <!-- Set the org.apache.log4j.helpers.LogLog.setQuiteMode. As of log4j1.2.8
      this needs to be set to avoid a possible deadlock on exception at the
      appender level. See bug#696819.
      -->
      <attribute name="Log4jQuietMode">true</attribute>
      <!-- How frequently in seconds the ConfigurationURL is checked for changes -->
      <attribute name="RefreshPeriod">60</attribute>
      
      <!-- The value to assign to system property jboss.server.log.threshold
           if it is not already set. This system property in turn controls
           the logging threshold for the server.log file.
           If the system property is already set when this service is created,
           this value is ignored. -->
      <attribute name="DefaultJBossServerLogThreshold">DEBUG</attribute>
   </mbean>

> Add <param name="Threshold" value="${jboss.server.log.threshold}"/> to the FILE appender config in jboss-log4j.xml.
> Log4j performs a system property substitution (see org.apache.log4j.xml.DomConfigurator.subst()). It doesn't seem to support our default value syntax, e.g. {jboss.server.log.threshold:DEBUG}, but starting the AS w/o setting the system property results in DEBUG logging.
> If we want a default other than DEBUG (or don't like counting on log4j to use DEBUG if the property isn't set), we can check the system property in Log4jService and set it if not set.
