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

Tomcat LogBackValve and ${catalina.base}
by Xavier Dury 26 Apr '13

26 Apr '13

Hi, I'm running multiple instances of tomcat which share a common ${catalina.home} folder while all specific settings are kept in ${catalina.base} folder. I wanted to use logback-access but noticed LogbackValve uses ${catalina.home} instead of ${catalina.base} when loading loback-access.xml. Shouldn't that be changed to ${catalina.base} knowing that ${catalina.base} defaults to ${catalina.home} when not specified? Regards, Xavier

Eclipse plugin not finding logback.xml
by Barry Hathaway 25 Apr '13

25 Apr '13

I have an Eclipse plugin (call it A) that uses and exports the logback classes. I have another plugin (call it B) that uses the above plugin and has a require-bundle in the manifest. When the plugin B starts up it can't find the logback.xml configuration file and as a result too much debugging information is generated. The logback.xml file resides in the bin directory of A and the run-time classpath has a "." so it should be on the classpath. I have looked at both bundles in the OSGi console and the exports/imports look correct. The logback.xml is found when I specify it as an VM argument. Any ideas why it is not found? Thanks in advance.

When I put localhost or any other address in my LAN as remoteHost it send event without problems. What I want to implement and I am curious about is how to log to public IP. Greetings, Alex

Serialization improvement
by Alf Kristian Støyle 24 Apr '13

24 Apr '13

Hi everyone. First off, my first mail on the mailinglist, thanks for logback, it is awesome :) We had a problem in our project that our serialized object graph was way too large. After digging, we found that a referenced ch.qos.logback.classic.Logger was the cause. A serialized object was about 27 kB, after making the referenced logger static, the serialized size was about 4,7kB ch.qos.logback.classic.Logger has several transient fields, but parent and childrenList are not. My guess is that when serializing a logger, you then implicitly serialize every referenced logger inn the logger tree. Am I correct? Since the readResolve method is only dependent on name, every field could be made transient, problem solved? Cheers, Alf

How to programmatically find an appender for a logger?
by Konstantinidis, Johannes 23 Apr '13

23 Apr '13

Hi all, I have a custom appender and sometimes I want to change its configuration at runtime. I would expect that the appenders are inherited in the same way as the log level. So when I get a Logger for "com.mycompany.foo" and ask for the log level, and I've specified the log level only for the root logger, then I get this log level. But when I ask the same logger for a specific appender (via myLogger.getAppender("myAppender")) and the appender is referenced by the root logger, then I get nothing. It seems that I have to know which logger references the appender. To me this doesn't seem right. Where is my mistake? If I could access the parent logger, then I might climb up the hierarchy and ask the parent loggers for the appender. But I also haven't found a method to get the parent logger.
