file name question
by Neil Lott 03 Feb '09

03 Feb '09

Here's my appender snippet. <appender name="MSA_LOG" class="ch.qos.logback.core.rolling.RollingFileAppender"> <file>/usr/local/mystro/logs/msa-mdn.log</file> <append>true</append> <rollingPolicy class="ch.qos.logback.core.rolling.FixedWindowRollingPolicy"> <FileNamePattern>/usr/local/neil/logs/msa-mdn-%i- %d{yyyyMMdd-HHmmss}.log</FileNamePattern> <MinIndex>1</MinIndex> <MaxIndex>5</MaxIndex> </rollingPolicy> <triggeringPolicy class="ch.qos.logback.core.rolling.SizeBasedTriggeringPolicy"> <MaxFileSize>10MB</MaxFileSize> </triggeringPolicy> <layout class="ch.qos.logback.classic.PatternLayout"> <Pattern> { %d{yyyyMMdd HHmmss.SSS} %msg \} %n</Pattern> </layout> </appender> I'd like to be able to start with a file name pattern for my initial file. Is there a way to do this? So instead of msa-mdn.log I'd like to have msa-mdn-0-20090203-042416.log or whatever the current time is as my initial file name. Also, I'd like to %d{yyyyMMdd-HHmmss} to have my date formatted in GMT time not local. How would I go about doing this? Thanks, Neil

SocketAppender
by Greg Flex 03 Feb '09

03 Feb '09

Hi all, I have a question about the SocketAppender. I understand that when the link to the server is down, clients trying write to it will be blocked. I was wondering if there's a way to prevent that. In other words, what would be the best way to prevent client from being block. Is there a way to "see" that the link to the server is down and if it is down lets direct messages to say, local drive. (instead of remote) Any suggestion? Ideas? Thanks a lot. Greg

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

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.

Logging to database
by Aswani 13 Jan '09

13 Jan '09

Hi everyone, In our application we log all events of all users to one log file. As we have many users, suppprt has become difficult. So we are exploring better ways. we have two options: 1) Seperating logging to different files, like one file per user. - There is a SiftingAppender in logback that serves this purpose. 2) Logging to database. (Our team is interested in this option) - Not one event at a time. Buffering all events of one client request and write all those buffered messages as one single string to Database at the end of the request. So the buffer should be thread local, or one buffer per user. I am just wondering is this possible with SiftingAppender? I saw CyclicBufferAppender in logback apidocs. But there is no documentation for that. If this appender is not for that purpose, Is there any appender that suits my requirement? So, I am thinking, instead of a FileAppender in the SiftingAppender, can we have any other appender that buffers all logging events of one client request? Am I thinking in the right direction?... Please help me in this regard... Thanks in advance!!!
