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

(Important) Dynamically change the scan period

hi all, i have migrated to logback to be able to change the log levels dynamically. i'm testing it now with calssfish 3.01 and somehow it is not working when i change the levels in logback.xml there nothing happens. by deploying from netbeans i get the following: |-INFO in ch.qos.logback.classic.turbo.ReconfigureOnChangeFilter@11bfee0 - Will scan for changes in [[C:\Dokumente und Einstellungen\user_Home\Eigene Dateien\NetBeansProjects\WS-LDAP\build\web\WEB-INF\classes\logback.xml]] every 15 seconds. but when i change the levels in this file nothing happens Any help will be appreciated Hugirat -- إِنَّ الَّذِينَ يُحِبُّونَ أَنْ تَشِيعَ الْفَاحِشَةُ فِي الَّذِينَ آمَنُوا لَهُمْ عَذَابٌ أَلِيمٌ فِي الدُّنْيَا وَالآخِرَةِ وَاللَّهُ يَعْلَمُ وَأَنْتُمْ لا تَعْلَمُونَ My public key please use it when you contact me: هذا مفتاحي العام الرجاء أستخدامه عند الإتصال بي: 09BA B710 4B98 ECDA 8C0A 6CB1 2E1E CF88 6A12 F2C3

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 & line conversion words not working
by Chris Cheshire 23 Feb '12

23 Feb '12

I have just upgraded to logback 1.0 (from 0.9.x), and now the conversion words for %class and %line just produce a question mark. My pattern layout is <layout class="ch.qos.logback.classic.PatternLayout"> <Pattern>%date [%thread] %-5level %logger %n%n Class : %class%n Line : %line%n%n%message%n</Pattern> </layout> Prior to the update this was working and now it's not. Everything else in the layout displays as specified, except %class and %line. I do have the java compiler generating debug information too. Any suggestions? Chris

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

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.

Time and Size Based Rolling Not Working
by Noman Amir Jamil 31 Dec '11

Hi, I have recently switched to logback for tomcat6 logging. I was able to successfully set it up and log files are being created and logged into. Following is my logback.xml: ================= <?xml version="1.0" encoding="UTF-8"?> <configuration> <appender name="CONSOLE" class="org.apache.juli.logging.ch.qos.logback.core.ConsoleAppender"> <encoder> <pattern>%d{HH:mm:ss.SSS} %-5level {%thread} [%logger{20}] : %msg%n</pattern> </encoder> </appender> <appender name="FILE-CATALINA" class="org.apache.juli.logging.ch.qos.logback.core.rolling.RollingFileAppender"> <file>${catalina.base}/logs/catalina.log</file> <append>true</append> <encoder> <charset>utf-8</charset> <pattern>%d{HH:mm:ss.SSS} %-5level {%thread} [%logger{40}] : %msg%n</pattern> </encoder> <rollingPolicy class="org.apache.juli.logging.ch.qos.logback.core.rolling.TimeBasedRollingPolicy"> <fileNamePattern>${catalina.base}/logs/catalina-%d{yyyyMMdd}-%i.log.zip</fileNamePattern> <maxHistory>60</maxHistory> <timeBasedFileNamingAndTriggeringPolicy class="org.apache.juli.logging.ch.qos.logback.core.rolling.SizeAndTimeBasedFNATP"> <maxFileSize>10KB</maxFileSize> </timeBasedFileNamingAndTriggeringPolicy> </rollingPolicy> </appender> <appender name="FILE-LOCALHOST" class="org.apache.juli.logging.ch.qos.logback.core.rolling.RollingFileAppender"> <file>${catalina.base}/logs/localhost.log</file> <append>true</append> <encoder> <charset>utf-8</charset> <pattern>%d{HH:mm:ss.SSS} %logger{0} {%thread} %level : %msg%n</pattern> </encoder> <rollingPolicy class="org.apache.juli.logging.ch.qos.logback.core.rolling.TimeBasedRollingPolicy"> <fileNamePattern>${catalina.base}/logs/localhost-%d{yyyyMMdd}-%i.log.zip</fileNamePattern> <maxHistory>60</maxHistory> <timeBasedFileNamingAndTriggeringPolicy class="org.apache.juli.logging.ch.qos.logback.core.rolling.SizeAndTimeBasedFNATP"> <maxFileSize>10KB</maxFileSize> </timeBasedFileNamingAndTriggeringPolicy> </rollingPolicy> </appender> <logger name="org.apache.catalina" level="INFO" additivity="false"> <appender-ref ref="FILE-CATALINA" /> </logger> <logger name="org.apache.catalina.core.ContainerBase.[Catalina].[localhost]" level="INFO" additivity="false"> <appender-ref ref="FILE-LOCALHOST" /> </logger> <root level="INFO"> <appender-ref ref="CONSOLE" /> </root> </configuration> ================= The logback jars being used are of version logback-0.9.30 as higher version doesn't work with tomcat6. The issue is that log files for localhost appender are being rolled over, but the catalina logs are not rolled over even after reaching the specified limit, unless I restart tomcat. The tomcat6 is running on Windows Server 2008. Can anybody help me with this? Thanks Noman A.

syslogAppender, suffixPattern, "valid conversion word"
by Ted Timmons 29 Dec '11

29 Dec '11

Hi. I have a file-based logback in place. I'm adding syslogging to it. Here's a sample configuration: <appender name="SYSLOG-MAIN" class="ch.qos.logback.classic.net.SyslogAppender"> <syslogHost>remotehost</syslogHost> <facility>local6</facility>    </appender> It works with the suffixPattern lines commented out. If I use the first line ("hello world"), I get the following: 01:46:35,272 |-INFO in ch.qos.logback.core.joran.action.AppenderAction - About to instantiate appender of type [ch.qos.logback.classic.net.SyslogAppender] 01:46:35,276 |-INFO in ch.qos.logback.core.joran.action.AppenderAction - Naming appender as [SYSLOG-MAIN] 01:46:35,293 |-ERROR in ch.qos.logback.core.pattern.parser.Compiler@2db7ae22 - There is no conversion class registered for conversion word [nopexsyslog] 01:46:35,293 |-ERROR in ch.qos.logback.core.pattern.parser.Compiler@2db7ae22 - [nopexsyslog] is not a valid conversion word Okay, I think I understand "nopex". But why isn't plain text acceptable? I get similar errors for the next two lines, which is what I'd actually like the logging to appear as. 01:20:12,978 |-ERROR in ch.qos.logback.core.pattern.parser.Compiler@31f9338f - There is no conversion class registered for conversion word [nopexatime] 01:20:12,978 |-ERROR in ch.qos.logback.core.pattern.parser.Compiler@31f9338f - [nopexatime] is not a valid conversion word I'm running logback-0.9.28.

Setting custom Profiler log level.
by César Álvarez Núñez 27 Dec '11

27 Dec '11

Hi all, Our application makes an intensive use of Profiler ( http://www.slf4j.org/extensions.html#profiler) It has been very useful during the development stage an we would like to keep it at production stage but there is a problem since its "log level" is hard-coded to "debug". Currently the profiler use the same application class logger so if log level is set to "info" in our production environment we lose the "profiler" log :-( Alternatives: - Use different loggers for application and profiler >-->> It requires to refactoring all the code and remember that any new Profiler that will be used need to set a custom logger instead of the default class logger. - Open a request to modify Profiler in order to set a custom log level. - Keep minimum log level to "debug" and make use of a Filter to accept any log event with marker=PROFILER, otherwise only accept if log level >= INFO >-->> It only will work with LogBack but Profiler belongs to SLF4J so it should work with any bridge. Any other way? BR, /César.

Best strategy for centralized logs in a multitenant environment
by Xavi Beumala 26 Dec '11

26 Dec '11

Hi all, I'm working on a multitenant application where I'd like to have different log files for each customer. I've been looking at the SiftingAppender and it seems to perfectly fit my needs. The application will run on a sessionless cluster, there isn't any kind of shard, each customer request can run on any node. Ideally I'd like to have a centralized log file for each customer and have the ability to hot change its configuraiton. What configuration would you better recommend? - DB based appender? - File based appender running prudent mode? - I've seen the scan="true" option to automatically reload the logging configuration. Ideally I'm looking for an option where automatically a configuration file could be hot plugged per tenant / customer. Is there any option so that scan=true checks a directory hierarchy? Many thanks for your help and recomendations. Much appreciated Xavi
