additional informations for appenders?
by Lars Fischer 27 Sep '11

27 Sep '11

Hello, I would like to use slf4j together with logback as logging framework. But I have some special requirements, which I'm not happy with them, but I can not drop them. 1) I need to transfer additional informations with each request to the appender. E.g. a thing like a "logDocumentId". Furthermore, I need to have multiple of such Ids active in one session/thread. I have to give the id int each request and an own appender implementation has to do something with it. What would be the best way to carry such Id besides the standard log message and parameters throug the slf4j api to the logback appenders? Can I store such objects in the MDC? How does this affect the performance, when used on every log request? Or would it be better to add the informations as additional elements at the end of the "argArray" parameter of the Logger methods, hoping that all appenders will ignore them, when there is no "{}" for the position? 2) I know that logback can be reconfigured on runtime, but all I know is that during this re-configuration, all log-requests will be droped. Is there a way to only add / remove / change a single TurboFilter or Appender without losing processing of requests by the "normal" loggers / appenders? Best regards, Lars

TLS problem in SMTPAppender
by Mark Woon 23 Sep '11

23 Sep '11

Ceki, In SMTPAppender, the TLS property is tied to the auth property and it shouldn't be. Mail servers can require TLS without requiring authentication. I've put in a pull request on github that removes the auth requirement if you enable TLS. For future reference, is the pull request sufficient, or do I need to open an issue, send email to the mailing list, etc? Thanks, -Mark

rolling in logback-android
by Peter Chmiel 23 Sep '11

23 Sep '11

Hi, Does logback-android support rolling? When I try using the configuration file below in an android app I get an error - No applicable action for [rollingPolicy]. But the same config works in a java project that uses logback. Thanks, Pete <configuration> <appender name="FILE" class="ch.qos.logback.core.rolling.RollingFileAppender"> <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy"> <FileNamePattern>logFile.%d{yyyy/MM/dd}.log</FileNamePattern> </rollingPolicy> <layout class="ch.qos.logback.classic.PatternLayout"> <Pattern>%-4relative [%thread] %-5level %logger{35} - %msg%n</Pattern> </layout> </appender> <root level="debug"> <appender-ref ref="FILE" /> </root> </configuration>

Tomcat 7 and LogbackValve - final method overridden
by Paul Gifford 22 Sep '11

22 Sep '11

Hi, We're migrating from Tomcat 6 to Tomcat 7. I was able to set up Tomcat 6 as instructed on this page: http://logback.qos.ch/access.html but when I try to do the same thing with Tomcat 7 I get the following exception: java.lang.VerifyError: JVMVRFY007 final method overridden; class=ch/qos/logback/access/tomcat/LogbackValve, method=stop()V, pc=0 This is because LogbackValve.stop() overrides public final synchronized void stop() in org.apache.catalina.util.LifecycleBase. LogbackValve.stop() just sets started=false. What are the consequences of removing the stop method from LogbackValve? The variable "started" isn't used elsewhere in the class, but it's package protected...I didn't look that closely to see if it's used in by other classes. If "started" isn't needed then I suggest removing it so the stop() method can be removed so LogbackValve will work with Tomcat 7. Paul

Logback Eclipse Plug-in - helping hands needed?
by Marcel Bruch 22 Sep '11

22 Sep '11

Hi logback-users, I'd like to know what plans exist for the Eclipse console plug-in within the next 6 months. Is anyone working on this view or has plans to do so in the next months? If not, I'd like to offer a helping hand on this. We offer an Eclipse hands-on as part of which students develop Eclipse plug-ins for various domains. An Eclipse plug-in for displaying log events inside Eclipse would be a well-scoped topic. So list-members, please let me know what your thoughts are (and maybe what features you'd like to see). Thanks, Marcel -- Eclipse Code Recommenders: w www.eclipse.org/recommenders tw www.twitter.com/marcelbruch g+ www.gplus.to/marcelbruch

DuplicatedMessageFilter with exclusions
by Rafael Marmelo 21 Sep '11

21 Sep '11

Hello, I'm using the DuplicatedMessageFilter to supress duplicated log messages and it works great. http://logback.qos.ch/apidocs/ch/qos/logback/classic/turbo/DuplicateMessage… Can I add exclusions to the filter? For instance, filter all messages except the ones from org.acme package. Do I have to create my own DuplicatedMessageFilter extension? Thanks. -- Rafael

Ceki, Yes. I am referring to https://github.com/tony19/logback-android I get the error No applicable action for [rollingPolicy]. I am not sure if I need to change something in the config file or if logback-android does not support rolling.
