Hi! It would be really nice if the jmxConfigurator action (in logback.xml) could be configured with an explicit ObjectName. I'm in the same situation as the original poster (we're running multiple instances of the same web-application in the same servlet container). Something like: <jmxConfigurator objectNameProperty="webapp=someWebApp" /> This would yield an ObjectName as: 'ch.qos.logback.classic:Name=default,webapp=someWebApp'. This would allow each web-app to have it's own mbean instance registered with the server. My choice is either to read up on the Joran configuration API and create a custom Action that will do the kind of MBean registration that I need, or to do some voodoo in our custom Logback loader. At the moment I'm doing some funky stuff in our loader: public class ExtensionAwareLogbackConfigurationLoader implements ServletContextListener { public static class NamedContext implements Context { private Context target; private String name; public NamedContext(Context target, String name) { this.target = target; this.name = name; } public StatusManager getStatusManager() {return target.getStatusManager();} public Object getObject(String s) {return target.getObject(s);} public void putObject(String s, Object o) {target.putObject(s, o);} public String getProperty(String s) {return target.getProperty(s);} public void putProperty(String s, String s1) {target.putProperty(s, s1);} public String getName() {return this.name;} public void setName(String s) {target.setName(s);} } public void contextInitialized(ServletContextEvent event) { ApplicationExtension ext = ApplicationExtension.get(); if(ext != null){ File configurationFile = ext.getRelativePath("log/logback.xml"); if(configurationFile.exists()){ try { event.getServletContext().log("["+ ExtensionAwareLogbackConfigurationLoader.class.getSimpleName()+"]: Using external logback.xml: "+configurationFile.getAbsolutePath()); LoggerContext loggerContext = (LoggerContext) LoggerFactory.getILoggerFactory(); loggerContext.putProperty("output.root", ext.getRelativePath("log/out").getAbsolutePath()); JoranConfigurator configurator = new JoranConfigurator(); configurator.setContext(new NamedContext(loggerContext, ext.getNamespace())); loggerContext.shutdownAndReset(); configurator.doConfigure(configurationFile); } catch (Exception e) { throw new RuntimeException(e); } } } } public void contextDestroyed(ServletContextEvent event) { LoggerContext loggerContext = (LoggerContext)LoggerFactory.getILoggerFactory(); loggerContext.shutdownAndReset(); } } I'm basically setting a custom name for the LoggerContext based on the current web-application context name. (The ApplicationExtension is an abstraction of a directory that contains resources per web-application == customer). Best Regards //Anders Ceki Gulcu-2 wrote:
Hello Ellis,
The context name cannot be set in logback.xml. It is the job of the context selector to set the logging context's name. See http://logback.qos.ch/manual/contextSelector.html for more details.
Please let us know if you need further information,

Hi,
I've currently got multiple logback-enabled servlets running under the same JVM, each in separate web contexts, and each with their own logback.xml and slf4j/logback jars in WEB-INF.
Whist this works (in terms of logging), the jmxConfigurator MBean seems to only refer to one of the contexts, and has the name 'default'. I can't see the loggers listed for the other contexts.
What I'd expected to see is a different MBean listed for each webapp context.
Looking at the jmxConfigurator code, it seems to use the name of the logging context for the JMX name; how does this get set? Can it be set in the logback.xml?
