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

logging output duplicated
by Chris Cheshire 02 Dec '08

02 Dec '08

In my webapp I am trying to send emails only on errors, with everything else logged to a file. I am using logback under slf4j, with the log4j/slf4j bridge for the external libraries that normally use log4j. My configuration file is reloaded in the servlet context init (using the Joran configurator example from the documentation) so I can set some system properties used in the appenders (like the context name). The logging config has : <root level="ERROR"> <appender-ref ref="EMAIL" /> <appender-ref ref="FILE" /> </root> <logger name="foo" level="DEBUG"> <appender-ref ref="FILE" /> </logger> *Everything* not of log level ERROR coming from foo is getting logged twice. Why? I've pored over Chapter 2 of the documentation and it seems to describe the opposite of what is happening. The level for foo will ideally swap between DEBUG and INFO, but I can't have things logged twice all the time. How do I fix this? Thanks Chris

Context selectors useful?
by Ceki Gulcu 01 Dec '08

01 Dec '08

Hello all, I am in the process of fixing bugs related to context selectors in logback. However, while sometime ago I thought that context selectors were the wave of the future, I am increasingly skeptical about their usefulness (of context selectors). If you are using context selectors, could you please explain why? -- Ceki Gülcü Logback: The reliable, generic, fast and flexible logging framework for Java. http://logback.qos.ch

smtpappender including INFO messages
by Chris Cheshire 29 Nov '08

29 Nov '08

I have my logger configured (theoretically) to only send emails when error events are received, which seems to be working, except that the content of the email not only includes the ERROR event, but any INFO events leading up to that event. I don't want *anything* but the logged ERROR event in the email. How do I remove all of this? Chris

variable substitution in logback 0.9.9
by Egon Exparotiminator 28 Nov '08

28 Nov '08

Hi, Does variable substitution works in a whole logback.xml? I'm using version 0.9.9. It works here: <configuration> <include file="${filec}"/> </configuration> and it works here: <include file="${user.pal}" /> but not here: <root> <level value="${logger.level}" /> <appender-ref ref="redirectConsole" /> </root> Should it work also in <level section? I'm asking because I'd like to configure different levels on different machines Thanks

Logback or Log4J Servers and Log4Cxx client
by Greg Flex 21 Nov '08

21 Nov '08

Hi Ceki, I know this isn't the right place/forum but I've noticed that the Log4cxx is using your server called: ShortSocketServer author: Ceki Gulcu and I'm having problems configuring it to work with Log4Cxx client. I was trying to get the Lockback SimpleSocketServer to communicate with Log4cxx client but I was unsuccessful too and in BOTH cases I got the following error: ERROR [main] org.apache.log4j.net.SocketNode (SocketNode.java:59) Could not open ObjectInputStream to Socket[addr=/127.0.0.1,port=2336,localport=6000] java.io.StreamCorruptedException: invalid stream header: 3C6C6F67 at java.io.ObjectInputStream.readStreamHeader(ObjectInputStream.java:783) at java.io.ObjectInputStream.<init>(ObjectInputStream.java:280) at org.apache.log4j.net.SocketNode.<init>(SocketNode.java:55) at org.apache.log4j.net.ShortSocketServer.main(ShortSocketServer.java:74) I thought maybe you could help me out a little... you know more about this than me :-) Is it even possible to mix these two guys and have them talk to each other? Please let me know. Thanks a lot. Greg.

Auto-append a log value
by Ingo Siebert 21 Nov '08

21 Nov '08

Hi, I want to append automatically an additional log value for every log message which is created. Reason is that I want to add a OSGi symbolic bundle name to every message. I've seen a blog entry which solved it with a marker, but I think it's error prone because you have to add the marker yourself for every log call. Any idea how to do this? Is it possible to set a listener for logged messages which can modify the log message? Cheers, Ingo

Converter Bug?
by Natan Cox 19 Nov '08

19 Nov '08

Hi, I'm trying to use a converter in HtmlLayout but it was not logged correctly. I'm basically getting a "PARSER_ERRER". I checked the code and found HTMLLayoutBase.start() does this.head = p.compile(t, getDefaultConverterMap()); where protected Map<String, String> getDefaultConverterMap() { return PatternLayout.defaultConverterMap; } But PatternLayoutBase.start() does this.head = p.compile(t, getEffectiveConverterMap()); and getEffectiveConverterMap loads the extra converters. kr, N

Logback Eclipse plugin installation
by Ettore Paolillo 18 Nov '08

18 Nov '08

Hi all, sorry for this newbie question that might have been asked (and answered) a million times :-( I installed the Logback plugin in my Eclipse installation (Ganymede) following the instructions given at http://logback.qos.ch/consolePlugin.html . No matter what I do, after re-launching Ganymede there is no Logback view available in my workspace. Should I configure something else or, are there any known issues with regard to Ganymede? Thank you in advance for your patience, Ettore Paolillo
