I have enhanced this one to make it affect for application scope

public static void changeLevel(Level level){
    if(level != null) {
        Ivy.log().setLevel(level);
        org.apache.log4j.Logger root = Logger.getRootLogger();
        Enumeration allLoggers = root.getLoggerRepository().getCurrentCategories();
        //set logging level of root and all logging instances in the system
        root.setLevel(level);
        while (allLoggers.hasMoreElements()){
            Category tmpLogger = (Category) allLoggers.nextElement();
            tmpLogger.setLevel(level);
        }
    }
}

Here is an Ivy project to do this stuff on engine (with GUI)

hi @Bruno Bütler It's seem that this setting only apply for project that we run this command. For other projects on same application ,it won't work. Is there any way to make it globally for engine? Thanks

The easiest way is to use a little process with a script step and the following code:

import org.apache.log4j.Level;
ivy.log.setLevel(Level.DEBUG as Level);
