Shibboleth IDP logs stopped generating after tomcat upgrade to 9.0.31

Hi All, We have been using shibboleth IDP and we noticed that the logs stopped generating after we upgraded tomcat from 9.0.15 to 9.0.31. No changes have been made to logback.xml. I have also checked that logback-core, logback-classic and slf4j-api jar files are present. Can anyone please guide us on how to troubleshoot this issue. Thanks, Regards, Kshitij Chug

logback does not print exception's cause
by 陌路人 18 Jun '20

18 Jun '20

Hi, Firstly thank you for your time. Sometimes, logback does not print exception's cause, I can't use the log to fix bug, as followings: 2020-06-09 16:54:32,393 ERROR [task-executor-27] [SimpleDispatcher.java:203] Exception occurred during dispatch web socket frame for uri[/ws/partydungeon/move] by uid[‪6493203‬]. java.lang.reflect.InvocationTargetException: null at sun.reflect.GeneratedMethodAccessor100.invoke(Unknown Source) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:498) at com.mitu.game.dispatcher.SimpleDispatcher$EventRunnable.doWebSocketMessage(SimpleDispatcher.java:187) at com.mitu.game.dispatcher.SimpleDispatcher$EventRunnable.run(SimpleDispatcher.java:106) at com.mitu.game.wrapper.ThreadPoolTaskExecutorEx$SafeRunnable.run(ThreadPoolTaskExecutorEx.java:74) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1149) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:624) at java.lang.Thread.run(Thread.java:748) Caused by: java.lang.NullPointerException: null 2020-06-09 16:54:32,405 INFO [nioEventLoopGroup-3-4] [SimpleLoggingHandler.java:35] IN {uid=‪5589867‬, forward=183.200.25.192, 183.200.25.192:24172, type=websocket, uri=/ws/user/bind, ts=‪1591692869‬} /10.0.0.70:34948 10 And the code is like:     private void doWebSocketMessage(Event event) {             String uri = "some uri";             String uid = "some id";             try {                 Object ret = action.method.invoke(action.instance, event.getData(), new Object[]{event});             } catch (Exception ex) {                 logger.error(String.format("Exception occurred during dispatch web socket frame for uri[%s] by uid[%s].", uri, uid), ex);             }         } I tried to look for answers by google and bing, but failed, and I tried to reproduce this problem, failed too, the cause can be printed, and it likes: java.lang.reflect.InvocationTargetException: null at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:498) at com.mitu.game.Application.main(Application.java:54) Caused by: java.lang.NullPointerException: null at com.mitu.game.Application$T.f(Application.java:42) ... 5 common frames omitted  the difference is NativeMethodAccessorImpl vs GeneratedMethodAccessor100, is it matter? I steped into the logback code, maybe the target of the exception is null, but I do not know the reason:( Thank you again, for your patient, and sorry for my poor english:( BR,Mike Yu

logback prints stack trace twice when writing to syslog

Hello, I am writing my dropwizard logs to syslog using logback pattern. I see an issue for stack traces prinitng it twice(once linearized and once as multi-line). Is there any parameter which could avoid this issue?

Create rolling file after application startup without losing events?
by Mark Raynsford 18 Apr '20

18 Apr '20

Hello! I have a small application that uses a rolling file appender in addition to logging to the console. I use the following small library to respect the various desktop standards on different platforms: https://www.io7m.com/software/jade/ Essentially, the problem I'm facing is that, for the file output, I don't know exactly where I'm going to log to until very shortly after application startup. Is it possible to defer the instantiation of the rolling file appender until I've worked out where the log files are going to go? I've tried to configure one programmatically, but it seems that the rolling file appender package is not exported. -- Mark Raynsford | https://www.io7m.com

Java 11 Compatibility
by Jonathan Scherman 07 Apr '20

07 Apr '20

Hi all, Just wanted to know if Logback was Java 11 compatible. The only trail that I've found about this was in the dependencies section <http://logback.qos.ch/dependencies.html> where is specified a requirement of Java 8. I don't understand if this is a strict dependency or just a dependency of Java >= 8. Best, Jonathan

What's best practices to maintain logger names in backend configuration files like logback.xml?
by Thorsten Schöning 03 Apr '20

03 Apr '20

Hi all, I'm using Logback mostly, but things are the same for other logging backends in the end. My current approach is to maintain `logback.xml` per deployment of some software project, which might be some daemon, web app or whatever. If it has an individual deployment and is known to use logging at all, it gets an individual config file. But should that file contain all logger names known and used by some application? I did so in the past to clearly document which loggers are available at all. Many of those are related to concrete classes and don't need to be configured individually in theory, but the most likely available root logger is enough already. OTOH, there are use cases for very specific loggers which additionally exist per class. Sometimes e.g. I have very special status loggers with very custom logging format which need to write some data to some special fail or send some mail or else. Because those are so special and need to be configured specially, they need to be part of the config file always. The downside of adding all loggers to those files clearly is maintenance overhead: The same logger might be available in multiple files, so renames need to be applied everywhere. Newly added loggers need to be added to all files, but one can't easily know if some class of some package is used in some app only only because some package/project is used in that app. The benefit of this approach clearly is that at best every admin always simply knows which loggers are available by looking into the config and can configure log levels for individual loggers of interest only. Otherwise one would need to start logging and blacklist things clearly not of interest. Does anyone else do this or is it not worth the effort? Thanks!

by Alexander Curvers 18 Mar '20

18 Mar '20

Dear mailinglist subscribers i would like to ask some help with a logback log mail change i want to make. I am using ch.qos.logback.classic.net.SMTPAppender with <cyclicBufferTracker class="*ch.qos.logback.core.spi.CyclicBufferTracke*r"> <bufferSize>4</bufferSize> </cyclicBufferTracker> <layout class="c*h.qos.logback.classic.html.HTMLLayout"*/> The error mails i receive inform me about ERRORS by mail the thing is i would like text not to get truncated i see some messages appear as: Read "application/json;charset=UTF-8" to [ProfileTextDto(text=bla bla bla bla( (truncated)...] it is unclear to me what exactly gets truncated, and i wonder if its easy to switch the truncating of by a setting or extending the class. I searched but did not find a solution thank you in advance. Kind regards, Alexander
