I'm unable to create a bugzilla account at http://bugzilla.slf4j.org/createaccount.cgi Could someone enter this bug report for me? If I change my version of logback to 0.9.11 I don't get this. I get it when I use logback version 0.9.13. I'm using version 1.5.5 of slf4j.

Logback Eclipse Plugin Status?
by Jeff Jensen 08 Feb '10

08 Feb '10

The download page [0] has had "It will be upgraded in the coming weeks." on it for quite a few months. Is there a status update to share? Is it being discontinued? Regarding the statement "It expects logback version 0.9.9.", will it fail with 0.9.18? I could not find a list of Eclipse versions it should work with. Anyone using it with Galileo? I was about to just "try it", but have had problems in the past trying to recover from incompatibilities, so hesitate. Also, as a feature, we were hoping for a simple picklist of log levels (or regexp to apply to the view) to real-time filter the view vs drop incoming messages. Any plans for a plugin update site vs manual install? [0] http://logback.qos.ch/download.html

logback equivalent to log4j SocketHubAppender
by D.M. 27 Jan '10

27 Jan '10

Hello to all, is there an equivalent in logback for the log4j Socket*Hub*Appender? We use this, to check the current logging via connecting Chainsaw to the remote logging machine from time to time. It is said, that this has very few overhead on the logging machine in the case, when no one is listening. Thanks in advance, Dieter Müller

by Shivashankar Heggade Ramachandra Bhatt 08 Jan '10

08 Jan '10

Hi, One of our MAVEN project is using Logback and it is having requirement to store the log content into MySQL db (version 5.0). Below are my Logback configuration and the output for the same. CONFIGURATION <configuration debug="false"> <appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender"> <layout class="ch.qos.logback.classic.PatternLayout"> <pattern>[%level] %X{module} %msg%n</pattern> </layout> </appender> <appender name="DB" class="ch.qos.logback.classic.db.DBAppender"> <connectionSource class="ch.qos.logback.core.db.DriverManagerConnectionSource"> <driverClass>com.mysql.jdbc.Driver</driverClass> <url>jdbc:mysql://localhost:3306/logback_db</url> <user>root</user> <password>mypassword</password> <insertHeaders>true</insertHeaders> </connectionSource> </appender> <root> <level value="${ROOT_LOGGER_LEVEL}"/> <appender-ref ref="DB" /> </root> <root> <level value="${ROOT_LOGGER_LEVEL}"/> <appender-ref ref="STDOUT"/> </root> </configuration> OUTPUT IN THE CONSOLE For correct db parameters [INFO] [app-core:internal] Driver name=MySQL-AB JDBC Driver Driver version=mysql-connector-java-5.0.8 ( Revision: ${svn.Revision} ) supportsGetGeneratedKeys=true true For wrong db parameters [INFO] [app-core:internal] false The above configuration is not creating any db tables and not able to store the content. Please let me know the necessary changes to these configurations.

Logback suddenly stopped logging
by Jorge Morales Pou 07 Jan '10

07 Jan '10

Hi cecki, >From the status messages we suspected the same as you, that it was caused by an IOException. Probably there are problems with disk (we are checking this) but the thing is that we were using log4j for 2 years now and working with no problems, and the day we switched to logback, we had this problem almost every hour (no fixed pattern here). We had do restart our application in order to get loggin back. Our disk was not full, so this is not the cause. We reverted back to log4j over slf4j, to get back logging without problems. Of course there are some differences between configuration from logback and log4j, so probably this configuration differences make it work without problem in log4j. I assume that the problem is an IOException on renaming the file that leaves the appender closed, so no more writing on this appender is possible. In our tests this didn't happen. we didn't test with as high througput as production environment, and also disks were different so the IOError might not have happened.

LoggingContext JNDI not working in Session EJB using Thread
by miguel goyena 07 Jan '10

07 Jan '10

Hi everybody: I'm starting using logback, and I have a strange behauvour of logback. I'm using LoggingContextSelect JNDI. My application es an ear deployed in JBOSS, with three WAR and a EJB session jar. One of the servlet in a WAR uses the Sesssion EJB. In the EJB Session Method I create a Thread, and start it MandarMensajes threadException = new MandarMensajes(tipo,cuantos,cadaCuanto); threadException.start(); In this thread the run method uses logback for logging. Logger logger = LoggerFactory.getLogger(this); logger.logDebug("Hola"); But the logger I get have a default context!!!!!!, not the context defined in the JNDI. Only happends this when a use the thread in the Session EJB. If I use the MandarMensajes thread in the servlet everything is correct. If I get a logger anywhere else in the EJB Session everything is correct. If I use the run() method in the EJB Session everything is correct. Even if I get the MDC objet when thread is executing, all the values I put in servlet are there; but the context is default, so it never uses my logback.xml!!!!. I don't know if it is a logback bug, or if I'm doing something wrong I don't know if I've explained myself correctly, sorry my english is poor Thanks a lot

Hi, In logback 0.9.17/0.9.18, StatusListenerAction does not set context to ContextAware StatusListener. Is it by design? Thanks, Tom
