Log messages in multithreaded applications
Hello, In multithreaded applications I got messages like 2011-09-04/01:50:22.515/PDT [AwtEventQueue-1] INFO Received: message Thus, private final Logger LOG = Logger.getLogger(this.getClass()); this.getClass() does not really make sense? How to enable log4j more specific what class makes the message in multithreaded applications? Also, is there any way to log automatically the name of a method? Thank you - To unsubscribe, e-mail: log4j-user-unsubscr...@logging.apache.org For additional commands, e-mail: log4j-user-h...@logging.apache.org
Re: Log messages in multithreaded applications
See: http://logging.apache.org/log4j/1.2/apidocs/org/apache/log4j/PatternLayout.html you want the %c specifier in your log4j configuration for the layout. If each of the classes that will be logging has (or inherits) an initializer like the one you mentioned then this.getClass() actually does make sense. Although being private, of course, means it will be inaccessible to subclasses.

Re: Log messages in multithreaded applications
See PatternLayout javadoc [1]. In any case, I think getLogger(Class) just creates confusion. It was added as a convenience because of the way most people name their loggers, using the package/class hierarchy. But really a logger name is just a string and getLogger(String) would have been sufficient (using getClass().getName()) and less confusing as it would have made clear to users that package/class is only one approach to naming loggers, not the only one.

Re: Changing Level of Logging during runtime
There used to be a nice open source, Struts-based, Log4j configuration app out there, but it seems to have disappeared. There's a simple one in the Log4j-sandbox you can try... http://svn.apache.org/repos/asf/logging/sandbox/log4j/log4j_sandbox/tags/LOG4J_SANDBOX_ALPHA3/src/java/org/apache/log4j/servlet/ConfigurationServlet.java Note that I specifically point to the tag LOG4J_SANDBOX_ALPHA3 because later tags were based on the now defunct Log4j-1.3 codebase and the trunk, I believe, continues to be based on the said defunct codebase.

The change in level should be in immediate effect i.e. when admin changes the level og logging from Debug to Info through UI Screen, the logging at debug level should be stopped immediately. - To unsubscribe, e-mail: log4j-user-unsubscr...@logging.apache.org For additional commands, e-mail: log4j-user-h...@logging.apache.org
Re: Log messages in multithreaded applications
Thank you, Tim and Jacob, the option %c and link for PatternLayout helped. - To unsubscribe, e-mail: log4j-user-unsubscr...@logging.apache.org For additional commands, e-mail: log4j-user-h...@logging.apache.org
