Re: [logback-user] Logback suddenly stopped logging

I had the same problem and I think I know why J Solaris does interrupt IO blocked thread which then causes the OutputStreamAppender to catch the IOException in line 218 (version 0.9.24). I actually run version 0.9.18 but this part has not change so I guess it will behave the same way. If we look at http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=4385444 InterruptedIOException should not be required by platform specification (sol) And log4j https://issues.apache.org/bugzilla/show_bug.cgi?id=44157 InterruptedIOException ignored by log4j I think it should be solved the same why } catch (InterruptedIOException iioe){ //give the thread a changes to act on interruption and then carry on Thread.currentThread().interrupt(); } catch (IOException ioe) { // as soon as an exception occurs, move to non-started state // and add a single ErrorStatus to the SM. this.started = false; addStatus(new ErrorStatus("IO failure in appender", this, ioe)); } I could not find the jira entry mentioned in this thread therefore I write it here J BTY the jvm option -XX:-UseVMInterruptibleIO does prevent the interruption by solaris but that's only a workaround and not solving the problem ;) Cheers Andy

Replacing JUL with logback with Tomcat
by Alex Glass 31 May '12

31 May '12

I have setup logback-access according to the documentation with a LogbackValve and my Tomcat instance is logging requests. However it seems Tomcat is still writing messages to the console using JUL. What is the best way to route these messages to logback? Do I configure Tomcat to use log4j and then try and bridge those messages into logback-classic or is there a less complicated way? In the past I followed these instructions [1] to get Tomcat logging with log4j but would rather just use logback going forward. Thanks, Alex http://mrhaki.blogspot.com/2011/02/configure-log4j-on-tomcat.html

Log Filtering base on issuing class (%C)

I can't seem to find out how to filter my logs bases on the class name that issued the logged statement. Is any of of the pre-shipped filters suitable for this task?

Hello, Is there a way to configure logback to rouge Java exceptions to the log file? I've got all my other messages going to my desired file successfully but exceptions still go to the console.

Localized log level names
by Dario Campagna 30 May '12

30 May '12

Hi all, Few days ago I started experimenting with the org.slf4j.cal10n package for generating localized logs using logback. That package easily allow one to obtain localized log messages. Since SLF4J does not support localization of logger names and I need them to be localized too, I made some modification to logback-classic and used CAL10N to internationalize level names. More precisely, I defined an enum type named Levels with the keys TRACE, DEBUG, INFO, WARN and ERROR. I created resource bundles for some locales, e.g. levels_ja.properties for the Japanese locale. I added to the Level class the constructor private Level(int levelInt, Enum<?> key) { this.levelInt = levelInt; IMessageConveyor mc = new MessageConveyor(Locale.getDefault()); this.levelStr = mc.getMessage(key); } Finally, I defined the TRACE, DEBUG, INFO, WARN and ERROR using the above constructor, e.g, for level TRACE public static final Level TRACE = new Level(TRACE_INT, Levels.TRACE); Thanks to this modification I am know able to obtain localized level names in log files. I am wondering if this changes may be useful for other logback users. If you have any suggestion/comment please do not hesitate to respond to this email. Cheers, Dario
