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

Are included files scanned
by Rosarin Jolly Roy 12 Feb '11

12 Feb '11

I have a top-level config file logback.xml and another file logback-included.xml. If I set the scan=true in the logback.xml file, will the included file also be scanned for changes? Is scan=true applicable for <included> tag as well? I find that the scanning doesn't happen, when I change the included file. Should I do anything special? --- logback.xml --- <configuration scan="true"> <include file="logback-included.xml" /> </configuration> --- logback-included.xml --- <included scan="true"> <appender name="FILE" class="ch.qos.logback.core.rolling.RollingFileAppender"> <file>mylog.log</file> <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy"> <FileNamePattern>mylog.log.%d{yyyy-MM-dd}</FileNamePattern> </rollingPolicy> <encoder> <pattern>%date %level [%thread] %logger{15} %msg%n</pattern> </encoder> </appender> <root> <level value="DEBUG" /> <appender-ref ref="FILE" /> </root> </included> _________________________________________________________________ Hotmail has tools for the New Busy.

Hang with SMTPAppender
by Jeff Jensen 14 Aug '10

14 Aug '10

Using Logback 0.9.24 and SLF4J 1.6.1. I'm trying to resolve a hang problem with the ch.qos.logback.classic.net.SMTPAppender in an integration test and using SubethaSMTP as the email server. We have many tests working with SubethaSMTP that send emails, but not with Logback, so I know it works for the non-Logback configuration. I've also seen SMTPAppender work in a different situation to the production email server. So I think I have a config error somewhere with Logback setup to SubethaSMTP, but not sure what, or there is an issue in the LB & SS interaction. This is the SMTPAppender config: <appender name="EMAIL" class="ch.qos.logback.classic.net.SMTPAppender"> <layout class="ch.qos.logback.classic.html.HTMLLayout"> <pattern>%date%contextName%thread%-5level%-55logger{55}%mdc%marker%msg</pattern> <throwableRenderer class="ch.qos.logback.classic.html.DefaultThrowableRenderer" /> </layout> <SMTPHost>${mail.host.name}</SMTPHost> <SMTPPort>${mail.port.number}</SMTPPort> <From>${batch.email.address.from}</From> <To>${batch.email.address.to.cmrdevelopers}</To> <Subject>${batch.email.subject.prefix}Log Email: %msg</Subject> <evaluator class="ch.qos.logback.classic.boolex.OnMarkerEvaluator"> <marker>EMAIL_DEVS</marker> </evaluator> </appender> It hangs on call to SocketInputStream.socketRead0(), which is a native method. Anyone seen/solved this before? The timeout value is 0 on the socket read (means wait forever), so it is waiting for a response to read. While I'm trying to resolve this, one thing I'd like to do is set the timeout value so at least it doesn't hang. I'm not sure how to do that with SMTPAppender - anyone know how? The SMTPAppender/SMTPAppenderBase class does not have a timeout property, but SMTPAppenderBase does pull system properties. I'm hoping there is a config file-based approach to do this though... The following is a call stack captured in the Eclipse debugger; the next line-step would go into socketRead0() and hang. org.eclipse.jdt.internal.junit.runner.RemoteTestRunner at localhost:3598 Thread [main] (Suspended) SocketInputStream.read(byte[], int, int) line: 129 TraceInputStream.read(byte[], int, int) line: 97 BufferedInputStream.fill() line: 218 BufferedInputStream.read() line: 237 LineInputStream.readLine() line: 75 SMTPTransport.readServerResponse() line: 1440 SMTPTransport.openServer(String, int) line: 1260 SMTPTransport.protocolConnect(String, int, String, String) line: 370 SMTPTransport(Service).connect(String, int, String, String) line: 275 SMTPTransport(Service).connect(String, String, String) line: 156 SMTPTransport(Service).connect() line: 105 Transport.send0(Message, Address[]) line: 168 Transport.send(Message) line: 98 SMTPAppender(SMTPAppenderBase<E>).sendBuffer(E) line: 292 SMTPAppender(SMTPAppenderBase<E>).append(E) line: 159 SMTPAppender(AppenderBase<E>).doAppend(E) line: 85 AppenderAttachableImpl<E>.appendLoopOnAppenders(E) line: 64 Logger.appendLoopOnAppenders(ILoggingEvent) line: 283 Logger.callAppenders(ILoggingEvent) line: 270 Logger.buildLoggingEventAndAppend(String, Marker, Level, String, Object[], Throwable) line: 471 Logger.filterAndLog_0_Or3Plus(String, Marker, Level, String, Object[], Throwable) line: 425 Logger.error(Marker, String) line: 592 LoggerEmailTest.testEmailSend() line: 99 NativeMethodAccessorImpl.invoke0(Method, Object, Object[]) line: not available [native method] NativeMethodAccessorImpl.invoke(Object, Object[]) line: 39 DelegatingMethodAccessorImpl.invoke(Object, Object[]) line: 25 Method.invoke(Object, Object...) line: 597 FrameworkMethod$1.runReflectiveCall() line: 44 FrameworkMethod$1(ReflectiveCallable).run() line: 15 FrameworkMethod.invokeExplosively(Object, Object...) line: 41 InvokeMethod.evaluate() line: 20 RunBefores.evaluate() line: 28 RunBeforeTestMethodCallbacks.evaluate() line: 74 RunAfters.evaluate() line: 31 RunAfterTestMethodCallbacks.evaluate() line: 82 SpringRepeat.evaluate() line: 72 SpringJUnit4ClassRunner.runChild(FrameworkMethod, RunNotifier) line: 240 SpringJUnit4ClassRunner(BlockJUnit4ClassRunner).runChild(Object, RunNotifier) line: 50 ParentRunner$3.run() line: 193 ParentRunner$1.schedule(Runnable) line: 52 SpringJUnit4ClassRunner(ParentRunner<T>).runChildren(RunNotifier) line: 191 ParentRunner<T>.access$000(ParentRunner, RunNotifier) line: 42 ParentRunner$2.evaluate() line: 184 RunBeforeTestClassCallbacks.evaluate() line: 61 RunAfterTestClassCallbacks.evaluate() line: 70 SpringJUnit4ClassRunner(ParentRunner<T>).run(RunNotifier) line: 236 SpringJUnit4ClassRunner.run(RunNotifier) line: 180 JUnit4TestClassReference(JUnit4TestReference).run(TestExecution) line: 46 TestExecution.run(ITestReference[]) line: 38 RemoteTestRunner.runTests(String[], String, TestExecution) line: 467 RemoteTestRunner.runTests(TestExecution) line: 683 RemoteTestRunner.run() line: 390 RemoteTestRunner.main(String[]) line: 197 Thread [ReaderThread] (Running) Thread [org.subethamail.smtp.server.SMTPServer] (Running) Thread [org.subethamail.smtp.server.Session-/127.0.0.1:3601] (Running)

custom levels
by Lars Fischer 28 Jul '10

28 Jul '10

Hello, I would like to switch an existing system from log4j to Logback. The current system extends org.apache.log4j.Level to define some custom additional levels and uses Logger#log(Priority priority, Object message) with the custom Level as priority. Is there a similar way to extend Logback with additional levels? Regards, Lars

RollingFileAppender Issues
by Omar Alrubaiyan 23 Jul '10

23 Jul '10

Hello,I’m trying to use logback for a distributed application that I’m working on. I have a custom appender that buffers log messages and then sends them over to a central logger via RMI. The central logger collects the logs and outputs them to a logback logger that uses a RollingFileAppender with a FixedWindowRollingPolicy and a SizeBasedTriggeringPolicy. The problem is when the log file hits the size limit instead of renaming the file and starting a new one it creates 10 (or whatever the max index is for the window) copies of the same file and slows down while failing to properly roll over. This results in (after the first rollover trigger) 1 + max index copies of the same file all of which are over the size limit. This issue does not occur when using the same logback configuration file on a single jvm setup. I’ve tried the following:- Did away with the custom appender on the clients side and just transmitted raw messages over RMI (i.e. only one central Logback logger is used). Did not resolve the issue.- Switched to a TimeBasedRollingPolicy, under this policy the archiving seems to work properly but the rollover never occurs (the original log file keeps growing).- Switched the central logger over to log4j, this fixed the issue, although I would rather use logback instead.Any ideas about what could be causing this?Thanks,Omar _________________________________________________________________ http://clk.atdmt.com/UKM/go/197222280/direct/01/ We want to hear all your funny, exciting and crazy Hotmail stories.

logback and manual rollover (from java)
by lgonggr 23 Jul '10

23 Jul '10

Hi, I used log4j before and I triggered my RollingFileAppender rollover() manually in some places (batches). I need to create seperate logfiles for each batch run. I want it to rollover using the FixedWindowRollingPolicy if the logfile exceeds 10MB and at the start of each batch run. I've migrated to logback now and it works well, but I can't figure out how to rollover my RollingFileAppender manually. What I have now : <appender name="EntityToCSV" class="ch.qos.logback.core.rolling.RollingFileAppender"> <File>/home/tomcat/overname_test_logs/EntityToCSV.log</File> <encoder> <pattern>%d{yyyy-MM-dd HH:mm:ss} %-5p [%t] %c{1}: %m%n</pattern> </encoder> <rollingPolicy class="ch.qos.logback.core.rolling.FixedWindowRollingPolicy"> <maxIndex>9</maxIndex> <FileNamePattern>/home/tomcat/overname_test_logs/EntityToCSV.log.%i</FileNamePattern> </rollingPolicy> <triggeringPolicy class="ch.qos.logback.core.rolling.SizeBasedTriggeringPolicy"> <MaxFileSize>10MB</MaxFileSize> </triggeringPolicy> </appender> <logger name="nl.realworks.apps.overname.EntityToCSV" level="INFO"> <appender-ref ref="EntityToCSV"/> </logger> in EntityToCSV.java : private static final Logger LOGGER = LoggerFactory.getLogger(EntityToCSV.class); public static void main(String[] args) throws Exception { OvernameUtils.manualRollover(LOGGER); // do stuff and log it in OvernameUtils.java : public static void manualRollover(Logger logger) { Utils.assertNotNull("logger is null.", logger); if (logger instanceof RollingFileAppender) { // <--- FAIL ! try { ((RollingFileAppender)logger).rollover(); } catch (Exception e) { logger.error("rollover failed.", e); } return; } String message = logger.getName() + " is not an instance of RollingFileAppender."; logger.error(message, new RuntimeException(message)); } This won't work of course as Logger != Appender. I have no idea how to get from the Logger to its Appender(s). In log4j you could just do getAppender() but this is not possible with org.slf4j.Logger Perhaps this is a totally wrong approach. Any tips would be greatly appreciated. -- View this message in context: http://old.nabble.com/logback-and-manual-rollover-%28from-java%29-tp2923714… Sent from the Logback User mailing list archive at Nabble.com.

Advice please
by Jesse Long 21 Jul '10

21 Jul '10

Hi All, Please advise me whether the following is possible, and how to go about implementing it in Logback. I have a web app, with servlets for the web pages, as well as soap web services. Additionally, I have some background threads that do all sorts of interesting things. The servlets, web services and background threads all use the same data model classes which are backed by an orm data access layer, which uses JDBC to get data from a DB. I want all logging that happens while handling a servlet request to go to one log file, all logging that happens while handling a soap web service call to go to another log file, and all logging that happens in a background thread to go to another log file. Also, I want to log all the data model, orm and JDBC layer information to separate log files at debug and up level. For example, imaging the following list of log events (in this order): Logger Level Expected log files x.soap info soap.log x.model info soap.log,model.log x.orm debug orm.log x.orm info soap.log,model.log,orm.log x.jdbc debug jdbc.log x.jdbc info soap.log,model.log,orm.log,jdbc.log x.soap calls x.model, which calls x.orm, which calls x.jdbc. Similar traces for x.servlet, x.helperthread etc. I cant use Logger name to decide which appenders log, but what can I use? How can I achieve this? I would appreciate any pointers. Thanks, Jesse
