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.

Re: [logback-user] TimeBasedRollingPolicy

Hi, sorry for popping up an old thread but i don't catch something: shouldn't the Logger when new event arrives check the last modification time of the log file and if it "is time" roll it over? i have the same configuration in servlet and script - rollover at midnight. in servlet everything works just fine. but in script, that is run from cron every 2 hours, events are always written in the same log. How can i make something, that doesn't run continually trigger rollover? -- View this message in context: http://www.nabble.com/TimeBasedRollingPolicy-tp19756004p22517998.html Sent from the Logback User mailing list archive at Nabble.com.

Invitation for beta users
by Loren Siebert 01 Apr '09

01 Apr '09

Hello- I'm putting together a service called StackHub that collects your app's logging events and makes the data available for reporting/ analysis/notification via a hosted web interface. I am looking for a few Logback users who would like to try out the service and hopefully give me some feedback on what's good and what isn't. Ideal beta users would have a Logback-enabled production application running on at least two hosts. Here is the signup link if you are interested: http://www.stackhub.com Thank you! -Loren

Verbose startup output
by Noam Tenne 31 Mar '09

31 Mar '09

Hey there I have recently noticed, that when starting up logback in our application, there is a very verbose output regarding the configuration of our appenders. For example: 09:55:12,868 |-INFO in ch.qos.logback.classic.joran.action.ConfigurationAction - debug attribute not set 09:55:12,868 |-INFO in ch.qos.logback.core.joran.action.AppenderAction - About to instantiate appender of type [ch.qos.logback.core.ConsoleAppender] 09:55:12,870 |-INFO in ch.qos.logback.core.joran.action.AppenderAction - Naming appender as [CONSOLE] 09:55:12,889 |-INFO in ch.qos.logback.core.joran.action.NestedComplexPropertyIA - Pushing component [layout] on top of the object stack. 09:55:12,920 |-INFO in ch.qos.logback.core.joran.action.AppenderAction - Popping appender named [CONSOLE] from the object stack 09:55:12,921 |-INFO in ch.qos.logback.core.joran.action.AppenderAction - About to instantiate appender of type [ch.qos.logback.core.rolling.RollingFileAppender] 09:55:12,922 |-INFO in ch.qos.logback.core.joran.action.AppenderAction - Naming appender as [FILE] 09:55:12,927 |-INFO in ch.qos.logback.core.joran.action.NestedComplexPropertyIA - Pushing component [rollingPolicy] on top of the object stack. 09:55:12,929 |-INFO in ch.qos.logback.core.rolling.FixedWindowRollingPolicy@2d04faf8 - Adding parent to RollingPolicy: FILE 09:55:12,931 |-INFO in ch.qos.logback.core.rolling.FixedWindowRollingPolicy@2d04faf8 - Will use zip compression ... This is all probably normal since it's on INFO level, and I've seen it in traces of other posts, but I was wandering if there is any way I can silence these messages, or add them to DEBUG level?

SocketAppender
by Greg Flex 26 Mar '09

26 Mar '09

Ceki Culcu Sorry for the empty message I just sent. I pressed the wrong button by mistake.... I have the following SocketAppender that uses the XMLLayout. <appender name="SOCKET" class="ch.qos.logback.classic.net.SocketAppender"> <RemoteHost>localhost</RemoteHost> <Port>7777</Port> <ReconnectionDelay>10000</ReconnectionDelay> <IncludeCallerData>true</IncludeCallerData> <layout class="ch.qos.logback.classic.log4j.XMLLayout"> <LocationInfo>true</LocationInfo> <properties>true</properties> </layout> </appender> I was wondering if it is possible to make a logback client that uses the above SocketAppender talk to a Log4j server. I tried this but the server throws an unknown exception when connection is made... Can SocketAppender and log4j.XMLLayout be combined like in the example above?

Programmmatically creating logger/appender/pattern
by Lance White 26 Mar '09

26 Mar '09

Has anyone got any examples on how to programmatically create a logger / appender / pattern et. al in-line in code? I can't for the life of me get this running. Currently I've got the appender (file appender in this case) creating the output files, but all I get in them is stuff like: %PARSER_ERROR_d:MODULE:%PARSER_ERROR_msg% Which looks like the pattern stuff isn't started up properly. Cheers Lance

Log context based log splitting in SocketServer
by Rick Janda 23 Mar '09

23 Mar '09

Hello everybody, I have the following setup: I have several web applications running in the same Tomcat instance. The JNDIContextSelector is used to give every deployed webapp its own logging context. With this setup it's quite easy to create separate log files for every deployed webapp locally. Now comes the point, where I could need your help. Some logging events shall be transmitted to a SocketServer and be split there again on several log files depending on their log context. I tried to setup a filter for this purpose in the SocketServer configuration but it couldn't find any means to access the logging context name from the LoggingEvent. Is their any other way to split the logging events in the SocketServer based on their source webapp? Thanks in advance for your help, Rick

JoranConfigurator
by Greg Flex 19 Mar '09

19 Mar '09

Hi All, I was wondering if there is an easy way to test the validity of an XML configuration file. Just as an example I have this now in the config file <blah blah blah> JoranConfigurator doConfigure accepts it and no exception is thrown. Nothing gets printed or written to a file etc. however I'd like to detect that the config file is messed up. Any suggestions? Thanks

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
