    Boot logging question

    Richard Achmatowicz Novice

      Hi

      I'm trying to get a trace of org.jboss.Shutdown and org.jboss.server.system.Server. I've found that JBoss's use of log4j is split between boot logging (where you configure log4j via a log4j.properties file in run.jar), server logging (where you configure log4j via server//conf/jboss-log4j.xml and application logging (where you configure log4j via log4j.properties in WEB-INF/classes).

      I have extraced logj4-trace.properties from run.jar and modified it to add an appender called SHUTDOWN and two categories to pickup the trace messages i'm interested in:

      log4j.rootCategory=TRACE#org.jboss.logging.XLevel, FILE, CONSOLE
      log4j.category.org.jboss.Shutdown=TRACE#org.jboss.logging.XLevel, SHUTDOWN
      log4j.category.org.jboss.system.server.Server=TRACE#org.jboss.logging.XLevel, SHUTDOWN

      ### A bootstrap file appender
      log4j.appender.FILE=org.jboss.logging.appender.FileAppender
      log4j.appender.FILE.File=${jboss.server.log.dir}/boot.log
      log4j.appender.FILE.layout=org.apache.log4j.PatternLayout
      log4j.appender.FILE.layout.ConversionPattern=%d{ABSOLUTE} %-5p [%c{1}] %m%n
      log4j.appender.FILE.Append=false

      log4j.appender.CONSOLE=org.apache.log4j.ConsoleAppender
      log4j.appender.CONSOLE.Target=System.out
      log4j.appender.CONSOLE.layout=org.apache.log4j.PatternLayout
      log4j.appender.CONSOLE.layout.ConversionPattern=%d{ABSOLUTE} %-5p [%c{1}] %m%n

      log4j.appender.SHUTDOWN=org.jboss.logging.appender.FileAppender
      log4j.appender.SHUTDOWN.File=${jboss.server.log.dir}/shutdown.log
      log4j.appender.SHUTDOWN.layout=org.apache.log4j.PatternLayout
      log4j.appender.SHUTDOWN.layout.ConversionPattern=%d{ABSOLUTE} %-5p [%c{1}] %m%n
      log4j.appender.SHUTDOWN.Append=false

      I start the server with
      ./run.sh -Dlog4j.configuration=log4j-trace.properties -c default
      and the trace statements appear on the console and boot log, but there is no log file shutdown.log created.

      I'm also getting occasional error messages like:
      log4j:WARN No appenders could be found for logger (org.jboss.mx.loading.RepositoryClassLoader).
      log4j:WARN Please initialize the log4j system properly.

      My question:
      1. is there anything obviously wrong with this log4j-trace.properties file which I am missing and which explains why the shutdown.log file is not getting created
      2. what is the best way to trap log.trace() messages on org.jboss.Shutdown and org.jboss.system.server.Server.
