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 Tomcat7 Logging with Logback?
by James Carr 17 Sep '13

17 Sep '13

Hi All, Is there a good tutorial or documentation on replacing Tomcat's default logging with logback? So far my searches turn up http://logback.qos.ch/access.html which only seems to work with access logs, not the actual server logging itself. Thanks, James

[Sifting Appender ] Programmatically
by M. MychaL 04 Apr '13

04 Apr '13

Hello, i have created a new configuration with some logger but without appender. I would like to create appender programmatically, to add them to their logger. And finally use MDC context to set which appender will log the messages... For moment, i have create FileAppender, Pattern & Encoder, Filter, Discriminator. I would like to link the FileAppender to SifitingAppender. How to do that ? there is no setparent or set*appender methods.... Any idea ? Thanks.

JMX registration on WebLogic 12.1.1
by gbonk 28 Feb '13

28 Feb '13

I've followed the documentation and my mBeans register them selves just fine in my instance of WebLogic ( now oracle 12.1.1c ). My problem is that when I invoke "setLoggerLevel" the update is not reflected in my Web Service endpoint when I'm writing a logging message. I've debugged this a little and it looks to me that there are two different LoggerContexts. The JMX mBean is using a different one then my application is. When debugging the mBean I can see that the logger level has been set for logger(id=128) but my endpoint the logger instance is different (id=239) therefore it appears they are two different contexts. Any ideas on how to fix this ? -- View this message in context: http://logback.10977.n7.nabble.com/JMX-registration-on-WebLogic-12-1-1-tp11… Sent from the Users mailing list archive at Nabble.com.

HTMLLayout programmatically - How?
by Michael Wiedau 28 Feb '13

28 Feb '13

Dear all, I have a question to HTMLLayout. I have written the following code: LayoutWrappingEncoder htmlEncoder = new LayoutWrappingEncoder(); HTMLLayout htmlLayout = new HTMLLayout(); htmlLayout.setPattern("%relative%thread%mdc%level%logger%msg"); htmlLayout.start(); htmlEncoder.setContext(loggerContext); htmlEncoder.setLayout(htmlLayout); htmlEncoder.start(); PatternLayoutEncoder encoder = new PatternLayoutEncoder(); encoder.setContext(loggerContext); encoder.setPattern("%r %thread %level - %msg%n"); encoder.start(); fileAppender.setContext(this.loggerContext); fileAppender.setFile(FilenameUtils.concat(storeLocation, "logFile.log.html")); fileAppender.setName("File Validation Log"); fileAppender.setEncoder(htmlEncoder); fileAppender.start(); this.logger.addAppender(fileAppender); StatusPrinter.print(loggerContext); But it does not log anything. It creates a html file but only includes the header line. Using the "encoder" it works fine. I don't want to use Logfiles and do this programmatically. Can anyone give me a hint what is wrong here? Best regards, Michael

Hi, I got the following error in my logs: 13:26:49.257 [Thread-5] DEBUG c.b.b.c.MyClass - ERROR in ch.qos.logback.core.FileAppender[USER_LOG] - IO failure in appender java.nio.channels.FileLockInterruptionException My config is as follows: <appender name="USER_LOG" class="ch.qos.logback.core.FileAppender"> <file>${MY_LOG_DIR}/MyFile.log</file> <prudent>true</prudent> <encoder> <pattern>%d{HH:mm:ss.SSS} [%thread] %X{COMP} %-5level %logger{36} - %msg%n</pattern> </encoder> </appender> What could be the cause?

Does SizeAndTime based RollingFileAppender support prudent mode
by Desmond Kirrane 20 Feb '13

20 Feb '13

Hi, I'm unsure from the documentation but does SizeAndTimeBasedFNATP support prudent mode. I have the following config: <appender name="FILE" class="ch.qos.logback.core.rolling.RollingFileAppender"> <prudent>true</prudent> <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy"> <fileNamePattern>target/Test-%d{yyyy-MM-dd}.%i.log</fileNamePattern> <timeBasedFileNamingAndTriggeringPolicy class="ch.qos.logback.core.rolling.SizeAndTimeBasedFNATP"> <maxFileSize>1KB</maxFileSize> </timeBasedFileNamingAndTriggeringPolicy> <maxHistory>30</maxHistory> </rollingPolicy> <encoder> <pattern>%d{HH:mm:ss.SSS} [%thread] %-5level %logger{36} - %msg%n</pattern> </encoder> </appender> I've tried this and logback doesn't complain and file does rollover but just wondering is the prudent flag used?
