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

How can we enable JMX for logback in WebSphere ? Currently do not see ch.qos.logback.classic.jmx.Configurator in jconsole though <jmxConfigurator/> tag exist in logback configuration file. logback 0.9.27 WebSphere 7.0 This is similar to one posted earlier -- http://www.qos.ch/pipermail/logback-user/2010-November/001886.html -Sumanth

Class not found exception for LoggingEventVO
by MDerr＠nycm.com 13 Jan '12

I have an application client set up to send a logging message over a bus using a logback JMSQueueAppender. Logback version is 0.9.24 and slf4j version is 1.6.1. This is running on a Websphere 7.0 server in Rational Application Developer 7.5. I've tested the bus and queue with a simple text message using the RAD Universal Test Client and that works fine, so at least the foundation is solid. When I log a message to the message queue, I wind up with the following stack trace under a wide variety of attempts: [8/11/10 14:44:16:223 EDT] 0000002b SystemOut O Exception CWSIA0122E: An exception occurred deserializing a message, exception: java.lang.ClassNotFoundException: ch.qos.logback.classic.spi.LoggingEventVO.

use of java.io.File in logback / Android
by Robert Schmid 08 Jul '11

08 Jul '11

I am about to implement an appender that I can use on Android. I'm guessing it won't be much more difficult than doing the same from log4j. The primary problem is that we can't really use java.io.File to access the file system. Android has its own File access API. I believe that this will be as simple as extending RollingFileAppender and overriding methods as needed to swap out the File access apis. Can anybody spot the flaw in my thinking? Are there other pitfalls I need to worry about?

using logback in an API w/o impacting other applications
by Richard Sand 07 Jun '11

07 Jun '11

Hi all, In an API I had to write for a client to interface with an COTS application, I used log4j to bridge to the COTS application's log capability. To totally isolate the usage of log4j in the API I created a wrapper around a Logger with its own Hierarchy. I'm wondering if there is an analogous mechanism for accomplishing this in logback. public final class AgentLogger { public static Hierarchy heirarchy = new Hierarchy(new RootLogger(Level.TRACE)); private Logger wl = null; /** * Private constructor * * @param name */ private AgentLogger (String name) { wl = heirarchy.getLogger(name); wl.setAdditivity(false); } Any advice appreciated. Thanks!

JDK14Appender for logback: Anybody written one?
by Thorbjørn Ravn Andersen 18 Apr '11

18 Apr '11

Hi. I have a situation where I have a Java EE 6 web profile application which currently means that it needs to run in Glassfish 3.0.1. The appropriate way to log under Glassfish 3.0.1 is using java.util.logging which works well with slfj4-jdk14-whatever but where the _configuration_ of the logging system inside Glassfish sucks in new and exciting ways, which I have decided not to use. Hence I have figured out that what would work fine for us would be to embed logback in our application, use our usual logback configuration files which filter out those things we dont need anyway, and then let logback just end up dumping the log statements actually to be logged to java.util.logging. In other words, I need a JDK14Appender for logback. Has anyone written such a beast? It is not part of the standard logback distribution L Thanks /Thorbjørn

log4j performance comparison
by hostalp＠post.cz 11 Apr '11

11 Apr '11

Hello, based on the old topic archived here for example: http://old.nabble.com/logback-performance-clarification-td9390741.html I performed set of similar tests with debug level actually enabled to see how does logback perform when actually logging. - I noticed slightly worse (than log4j) logback performance in most cases, especially on my Windows machine - I was also interested in the effect of immediateFlush option which was giving us noticable performance improvement with log4j, but was removed from logback as of 0.9.19 (http://logback.qos.ch/manual/appenders.html) Here I noticed that immediateFlush was still giving something (I had to test on logback 0.9.18 in order to compare that). Sad that it was removed. - I've also done some more tests with info level and logback parametrized debug call combined with isDebugEnabled and this one shows typically better performance than plain parametrized debug call as well as classic debug call with isDebugLevel. The main question is - why was immediateFlush removed when it really gives some improvement? Here are some results (all tests performed on Java 1.5 due to its use by the application server we're running at): Windows: log4j 1.2.16, logback 0.9.28 immediateFlush true: ############################################### Log4j direct debug call: 13516 Log4j tested (isDebugEnabled) debug call: 13595 Logback direct debug call: 15593 Logback tested (isDebugEnabled) debug call: 17273 Logback parametrized debug call: 19011 ############################################### Windows: log4j 1.2.16, logback 0.9.18 immediateFlush true: ############################################### Log4j direct debug call: 13421 Log4j tested (isDebugEnabled) debug call: 13240 Logback direct debug call: 15562 Logback tested (isDebugEnabled) debug call: 17112 Logback parametrized debug call: 17981 ############################################### Windows: log4j 1.2.16, logback 0.9.18 immediateFlush false: ############################################### Log4j direct debug call: 6562 Log4j tested (isDebugEnabled) debug call: 6608 Logback direct debug call: 6137 Logback tested (isDebugEnabled) debug call: 7418 Logback parametrized debug call: 8273 ############################################### HP-UX: log4j 1.2.16, logback 0.9.28 immediateFlush true: ############################################### Log4j direct debug call: 17385 Log4j tested (isDebugEnabled) debug call: 17411 Logback direct debug call: 17351 Logback tested (isDebugEnabled) debug call: 17315 Logback parametrized debug call: 17677 ############################################### HP-UX: log4j 1.2.16, logback 0.9.18 immediateFlush true: ############################################### Log4j direct debug call: 17522 Log4j tested (isDebugEnabled) debug call: 17688 Logback direct debug call: 17418 Logback tested (isDebugEnabled) debug call: 17525 Logback parametrized debug call: 17071 ############################################### HP-UX machine: log4j 1.2.16, logback 0.9.18 immediateFlush false: ############################################### Log4j direct debug call: 9936 Log4j tested (isDebugEnabled) debug call: 10869 Logback direct debug call: 9900 Logback tested (isDebugEnabled) debug call: 9907 Logback parametrized debug call: 10346 ############################################### code used for testing ---------------------------------------------------------------------------------------------- package perfTest.ch.qos.logback;

Spring -> SLF4J -> Logback

Hello. I am trying to integrate Logback for the first time in a project of mine, and i'm having such a hard time trying to use it along with Spring 3.0.5. I declared jcl-over-slf4j dependency so it replaces commons-logging used by spring-core, but it seems like something is missing or wrong: java.lang.NoSuchMethodError: org.slf4j.spi.LocationAwareLogger.log(Lorg/slf4j/Marker;Ljava/lang/String;ILjava/lang/String;[Ljava/lang/Object;Ljava/lang/Throwable;)V at org.apache.commons.logging.impl.SLF4JLocationAwareLog.info(SLF4JLocationAwareLog.java:159) at org.springframework.jca.context.SpringContextResourceAdapter.start(SpringContextResourceAdapter.java:151) ...

We want to analysis files generated by Logback fileappender Which should be best log viewer for this? Do any log viewer provides web interface (servlet) for displaying files generated by logback file appender I understand that lilith is for online viewing of logevents generated by socket appender and for generating log file based on collected log events
