How about LogMF or LogSF in Log4j's own "Extras" companion?

You probably mean that you want to avoid expensive string concatenation and toString() operations if you logging is not logged anyway. There are a number of solutions to avoid that using log5j<http://code.google.com/p/log5j/>or logback <http://logback.qos.ch/>. regards, Wim 2008/4/4, Tim Nguyen <[EMAIL PROTECTED]>:Thank you! It is similar to what I wanted to do. This is more like the solution for one class. Is there anyway to check for all classes? I have hundreds of classes and I want to have an util that I can just replace the current logging (e.g: logger.debug("String")) with LogUtil (e.g: LogUtil.debug("String") and it does the trick. That way I can just replace All the logger with LogUtil :) Thanks again for your help! ----- Original Message ---- From: Robert Pepersack <[EMAIL PROTECTED]> To: Log4J Users List <log4j-user@logging.apache.org> Sent: Friday, April 4, 2008 12:14:30 PM Subject: Re: Log Utility Hi Tim, The Logger class has a way of checking the level first. First put this in your instance variables: private static final Logger logger = Logger.getLogger("my.package.MyClass"); private final boolean debug = logger.isDebugEnabled(); Then put this in your method: if (this.debug) { logger.debug(new String("test")); } Hope this helps.

For example, if my log level is INFO, and I call: log.debug(new String("test")); It will still instantiate the String object even thought it doesn't log anything. So I would like to write an Utility to check the level first, if the log level is lower, then I don't have to instantiate the object and just skip it. Anybody knows what is the easy way to do that?
