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.

TimeBasedRollingPolicy
by Lang, Johannes 18 Mar '09

18 Mar '09

Hello, i'm trying to get a RollingFileAppender with a TimeBasedRollingPolicy working, but i don't succeed. Here's my Appender-Configuration (which i copied from the logback-manual; only changed the layout): <appender name="FILE" class="ch.qos.logback.core.rolling.RollingFileAppender"> <File>logFile.log</File> <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy"> <FileNamePattern>logFile.%d{yyyy-MM-dd_HH-mm}.log</FileNamePattern> </rollingPolicy> <layout class="ch.qos.logback.classic.PatternLayout"> <Pattern>%d{HH:mm:ss.SSS} [%thread] %-5level %logger{36} - %msg%n</Pattern> </layout> </appender> And this is some of the debug-output from the Joran-Configurator: 09:06:48,703 |-INFO in ch.qos.logback.core.joran.action.AppenderAction - Naming appender as [FILE] 09:06:48,734 |-INFO in ch.qos.logback.core.joran.action.NestedComponentIA - Pushing component [rollingPolicy] on top of the object stack. 09:06:48,734 |-INFO in c.q.l.core.rolling.TimeBasedRollingPolicy - Adding parent to RollingPolicy: FILE 09:06:48,734 |-INFO in c.q.l.core.rolling.TimeBasedRollingPolicy - No compression will be used 09:06:48,734 |-INFO in c.q.l.core.rolling.TimeBasedRollingPolicy - Will use the pattern logFile.%d{yyyy-MM-dd_HH-mm}.log for the active file 09:06:48,750 |-INFO in c.q.l.core.rolling.TimeBasedRollingPolicy - The date pattern is 'yyyy-MM-dd_HH-mm' from file name pattern 'logFile.%d{yyyy-MM-dd_HH-mm}.log'. 09:06:48,750 |-INFO in c.q.l.core.rolling.TimeBasedRollingPolicy - Roll-over every minute. 09:06:48,750 |-INFO in ch.qos.logback.core.rolling.RollingFileAppender[FILE] - Active log file name: logFile.log 09:06:48,750 |-INFO in ch.qos.logback.core.joran.action.AppenderAction - Popping appender named [FILE] from the object stack 09:06:48,750 |-INFO in ch.qos.logback.classic.joran.action.LevelAction - root level set to TRACE 09:06:48,750 |-INFO in ch.qos.logback.core.joran.action.AppenderRefAction - Attaching appender named [stout] to Logger[root] 09:06:48,750 |-INFO in ch.qos.logback.core.joran.action.AppenderRefAction - Attaching appender named [FILE] to Logger[root] 09:06:48,750 |-INFO in ch.qos.logback.classic.joran.action.ConfigurationAction - End of configuration. Everything seems correct. "Roll-over every minute" is just what i want to do. But what really happens is, that all logging is written to the file "logFile.log". There is no rollover. Any suggestions what's wrong with my appender-config? Cheers Johannes

I've got a Maven project that (currently) produces 5 war files from 7 Maven modules. Can I configure Logback in one war file and have it work for all of the war files? Thanks in advance, Brian

Local/Remote config management at runtime
by Paul G 04 Feb '09

04 Feb '09

We have a requirement that we would like to centrally manage logging configuration files and push these out to applications as and when needed. So my questions are. Is it possible to reconfigure using Joran at runtime rather than one at initialisation time, are there any potential side effects? It would be fairly simple to write some code to listen for JMS or on a port to receive a message which would receive a Logback configuration, but would would be the message format? A logback configuration xml file how do then then pass that into Joran? The sending on messages is no problem as we would just create our own appender or use something like JMS appender to centralise log data collection. Any ideas would be great?

Jetty RequestLog in logback distribution
by Russell E Glaue 20 Jan '09

20 Jan '09

We were researching the implementation of logback as a Jetty RequestLog, and my colleague came upon an implementation written by "Ceki Gülcü, Sébastien Pennec". http://logback.qos.ch/apidocs/ch/qos/logback/access/jetty/package-summary.h… http://logback.qos.ch/apidocs/ch/qos/logback/access/jetty/RequestLogImpl.ht… This is distributed as part of the logback release. And I found a posting from 2006 by Sébastien of his communication to the Jetty mail list about this. [Jetty-support] RequestLog configuration of the maven plugin http://markmail.org/message/llgeu4gnaub4ppgm#query:Jetty%20logback%20Reques… Other than the API documentation, I did not find any other documentation or explaination on this subclass written for Jetty, ch.qos.logback.access.jetty.* Could someone elaborate on this? Is this complete code implementing Jetty's RequestLog interface? Thank you. -RG

Wrong Encoding in SMTPAppender
by alex 16 Jan '09

16 Jan '09

Hi, I configured my SMTPAppender like this <appender name="email" class="ch.qos.logback.classic.net.SMTPAppender"> <Subject>Error on - %p%nopex</Subject> <Encoding>UTF-8</Encoding> <SMTPHost>192.168.11.41</SMTPHost> <To>error(a)xxxxxxxx.xx</To> <From>error(a)xxxxxxx.xx/From> <layout class="ch.qos.logback.classic.PatternLayout"> <pattern>%date [%thread] %-5level %logger{50} - %msg%n%ex</pattern> </layout> </appender> The email is sent from code : log.error("Ordine " + myOrderHeader.getIdorder() + " è stato pagato ma il prodotto è già SCADUTO !! Res / Item " + myOrderHeader.getIdreseller() + " / " + itemMaster.getItemId()); And this is the mail source : ------=_Part_82_50553.1232007757067 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: quoted-printable 2009-01-15 09:22:37,067 [http--80-8] ERROR it.dnshst.useritem.UserItem - Or= dine 158 =E8 stato pagato ma il prodotto =E8 gi=E0 SCADUTO !!

File not rolling over with SizeBasedTriggeringPolicy
by Gianni Doe 16 Jan '09

16 Jan '09

Hi My log files are not rolling over with the following appender and they grow indefinitely in size: <appender class="ch.qos.logback.core.rolling.RollingFileAppender" name="R"> <File>${catalina.home}/logs/rp.log</File> <Append>true</Append> <filter class="ch.qos.logback.classic.filter.ThresholdFilter"> <level>debug</level> </filter> <rollingPolicy class="ch.qos.logback.core.rolling.FixedWindowRollingPolicy"> <FileNamePattern>rp.%i.log.gz</FileNamePattern> <MinIndex>1</MinIndex> <MaxIndex>3</MaxIndex> </rollingPolicy> <TriggeringPolicy class="ch.qos.logback.core.rolling.SizeBasedTriggeringPolicy"> <MaxFileSize>5MB</MaxFileSize> </TriggeringPolicy> <layout class="ch.qos.logback.classic.PatternLayout"> <Pattern>%-30(%d{HH:mm:ss.SSS} [%thread]) %-5level %logger{64} - %msg %n</Pattern> </layout> </appender> At some point this appender was working correctly so I'm a bit baffled - any suggestions for debugging why it's not working would be appreciated. Thanks Gianni PS. Not sure if this is relevant but I've been upgrading logback as new versions have been released but I couldn't say if it stopped working with a particular release or not.

strange MDC and SMTPAppender behavior
by Lucas, Casey 15 Jan '09

15 Jan '09

I'm seeing unexpected behavior when I combine MDC and SMTPAppender. The MDC values appear to be lost for previous log messages when MDC.clear is called before Logger.error triggers the actual email. This does not appear to be a problem with console appender. Below is a test program that will reproduce the problem. A logback.xml that uses an SMTPAppender and a pattern that includes %mdc is required. Is there something I'm missing? Versions: slf4j-api-1.5.6.jar logback-core-0.9.14.jar logback-classic-0.9.14.jar janino-2.5.14.jar mail-1.4.1.jar java version "1.6.0_04" test program: import org.slf4j.Logger; import org.slf4j.MDC; import org.slf4j.LoggerFactory; public class TestMain { public static void main(String[] args) { Logger logger = LoggerFactory.getLogger("TestMain"); // test1... logger.debug("test1: should not have MDC"); MDC.put("key1", "val1"); MDC.put("key2", "val2"); logger.warn("test1: should have MDC(key1=val1,key2=val2) but does not"); MDC.clear(); logger.debug("test1: should not have MDC"); logger.error("test1: error message triggers email"); // test2... logger.debug("test2: should not have MDC"); MDC.put("key1", "val1"); logger.warn("test2: should have MDC(key1=val1)"); MDC.put("key2", "val2"); logger.warn("test2: should have MDC(key1=val1,key2=val2)"); MDC.put("key3", "val3"); logger.warn("test2: should have MDC(key1=val1,key2=val2,key3=val3) but does not"); MDC.clear(); logger.debug("test2: should not have MDC"); logger.error("test2: error message triggers email"); // test3... logger.debug("test3: should not have MDC"); MDC.put("key1", "val1"); logger.warn("test3: should have MDC(key1=val1)"); MDC.put("key2", "val2"); logger.warn("test3: should have MDC(key1=val1,key2=val2)"); MDC.put("key3", "val3"); logger.warn("test3: should have MDC(key1=val1,key2=val2,key3=val3)"); MDC.put("key4", "val4"); logger.warn("test3: should have MDC(key1=val1,key2=val2,key3=val3,key4=val4) but does not"); MDC.clear(); logger.debug("test3: should not have MDC"); logger.error("test3: error message triggers email"); // test4... logger.debug("test4: should not have MDC"); MDC.put("key1", "val1"); logger.warn("test4: should have MDC(key1=val1)"); MDC.put("key2", "val2"); logger.error("test4: error message triggers email and has MDC(key1=val1,key2=val2)"); MDC.clear(); logger.debug("test5: should not have MDC"); MDC.put("key1", "val1"); logger.warn("test5: should have MDC(key1=val1) but does not"); MDC.clear(); logger.debug("test5: should not have MDC"); MDC.put("key1", "val1"); logger.warn("test5: should have MDC(key1=val1)"); logger.error("test5: error message triggers email and should not have MDC"); } }

Logback and Log4j plugins
by Greg Flex 13 Jan '09

13 Jan '09

Hi Guys, I'm still trying to make a logback server talk to the log4cxx client. I got it to work (with a lot of research done on-line and help of others) with Log4j. I used a plugin in my .xml file that sets the server up. Here is an example of it: <plugin name="XMLSocketReceiver" class="org.apache.log4j.net. XMLSocketReceiver"> <param name="Port" value="7776"/> </plugin> I set my server's port to 7777, a value passed in as a parameter to the main() This port accepts all the connections coming from other log4j clients. The plugin specifies port 7776 and it allows the communication coming from the log4cxx clients to the server. It all works just fine and I see both messages written to the file. (using a rolling file appender) I was wondering if there is a way to set the logback server in a similar way. (maybe use a plugin above? ) Any thoughts about this? Any suggestions? Thanks Greg.
