logback.xml with include
by Ted Meng 24 Mar '10

24 Mar '10

Hi: I put an include directive in my logback.xml <configuration> <include file="includedConfig.xml" /> </configuration> the "includedConfig.xml" is in the same directory (classpath) as the logback.xml file itself. But logback runtime keeps saying [java] 03:21:41,533 |-ERROR in ch.qos.logback.core.joran.action.IncludeAction - File [includedConfig.xml] does not exist. java.io.FileNotFoundException: logback.xml (The system cannot find the file specified) Using a absolute path is not a choice here so I wonder what would be the best way to do this or maybe I misunderstand something. Thanks -Ted

logback output date using GMT instead of local time
by Ted Meng 24 Mar '10

24 Mar '10

Hi, I do not remember seeing it in the past but today I used the following simple program to print out log message with slf4j/logback. and to my surprise, it is outputing with GMT time instead of my local time. In other words, slf4j/logback would always print out datetime using GMT for PatternLayout like the following <layout class="ch.qos.logback.classic.PatternLayout"> <Pattern>%d{MM/dd/yyyy-HH:mm:ss,SSS} %5level %class{1}:%line - %msg%n</Pattern> </layout> am I doing something wrong or is there a config option to specify output local time instead of the default GMT time.? Thanks very much. Below is the simple program to print out the time that indictates it is using GMT instead of localtime. import org.slf4j.Logger; import org.slf4j.LoggerFactory; public class L { public static final Logger log = LoggerFactory.getLogger(L.class); public static void main(String[] args) { log.info("test"); } }

logback always printing status information?!
by Christian Migowski 23 Mar '10

23 Mar '10

Hi, for some reasons logback always prints out it's status/debug information to STDOUT although I didn't ask for it, what could be the reason for this? I have this very simple logback.xml file which path I pass through command line parameter -Dlogback.configurationFile=/home/u123456/bmbstatistics/conf/logback.xml (it was created using the translator tool on the website from a log4j properties file (which btw doesn't "transfer" the properties like LOG_PATH, so a little manual modification was necessary) <?xml version="1.0" encoding="UTF-8"?> <configuration> <property name="GENERIC_PATTERN" value="[%d{dd.MM.yyyy HH:mm:ss.SSS}] [%t] [%-5p] [%c{2}] %m%n" /> <property name="LOG_PATH" value="./log" /> <appender name="FileAppender" class="ch.qos.logback.core.rolling.RollingFileAppender">  <File>${LOG_PATH}/statistics.log</File> <layout class="ch.qos.logback.classic.PatternLayout"> <Pattern>${GENERIC_PATTERN}</Pattern> </layout> <rollingPolicy class="ch.qos.logback.core.rolling.FixedWindowRollingPolicy"> <maxIndex>20</maxIndex> <FileNamePattern>${LOG_PATH}/statistics.log.%i</FileNamePattern> </rollingPolicy> <triggeringPolicy class="ch.qos.logback.core.rolling.SizeBasedTriggeringPolicy"> <MaxFileSize>20MB</MaxFileSize> </triggeringPolicy> </appender> <root level="DEBUG"> <appender-ref ref="FileAppender"/> </root> </configuration> When I start my application with this config the following appears on stdout: 12:55:20,531 |-INFO in ch.qos.logback.classic.LoggerContext[default] - Found resource [FILE:/home/u123456/bmbstatistics/conf/logback.xml] at [file:/home/u123456/bmbstatistics/conf/logback.xml] 12:55:20,687 |-INFO in ch.qos.logback.classic.joran.action.ConfigurationAction - debug attribute not set 12:55:20,688 |-INFO in ch.qos.logback.classic.turbo.ReconfigureOnChangeFilter@291946c2 - Will scan for changes in file [/home/u123456/bmbstatistics/conf/logback.xml] every 60 seconds. 12:55:20,688 |-INFO in ch.qos.logback.classic.joran.action.ConfigurationAction - Adding ReconfigureOnChangeFilter as a turbo filter 12:55:20,690 |-INFO in ch.qos.logback.core.joran.action.AppenderAction - About to instantiate appender of type [ch.qos.logback.core.rolling.RollingFileAppender] 12:55:20,698 |-INFO in ch.qos.logback.core.joran.action.AppenderAction - Naming appender as [FileAppender] 12:55:20,748 |-INFO in ch.qos.logback.core.joran.action.NestedComplexPropertyIA - Pushing component [layout] on top of the object stack. 12:55:20,814 |-INFO in ch.qos.logback.core.joran.action.NestedComplexPropertyIA - Pushing component [rollingPolicy] on top of the object stack. 12:55:20,827 |-INFO in ch.qos.logback.core.rolling.FixedWindowRollingPolicy@3a747fa2 - No compression will be used 12:55:20,828 |-WARN in ch.qos.logback.core.rolling.FixedWindowRollingPolicy@3a747fa2 - Large window sizes are not allowed. 12:55:20,828 |-WARN in ch.qos.logback.core.rolling.FixedWindowRollingPolicy@3a747fa2 - MaxIndex reduced to 13 12:55:20,832 |-INFO in ch.qos.logback.core.joran.action.NestedComplexPropertyIA - Pushing component [triggeringPolicy] on top of the object stack. 12:55:20,840 |-INFO in ch.qos.logback.core.rolling.RollingFileAppender[FileAppender] - Active log file name: ./log/bmbstatistics.log 12:55:20,840 |-INFO in ch.qos.logback.core.rolling.RollingFileAppender[FileAppender] - File property is set to [./log/bmbstatistics.log] 12:55:20,841 |-INFO in ch.qos.logback.core.joran.action.AppenderAction - Popping appender named [FileAppender] from the object stack 12:55:20,841 |-INFO in ch.qos.logback.classic.joran.action.RootLoggerAction - Setting level of ROOT logger to DEBUG 12:55:20,842 |-INFO in ch.qos.logback.core.joran.action.AppenderRefAction - Attaching appender named [FileAppender] to Logger[ROOT] How can I disable this logging to stdout? thanks in adavance, regards, christian!

Why is SMTPAppenderBase.setCharsetEncoding not public
by Andreas Dejung 21 Mar '10

21 Mar '10

Hi all Is there a specific reason why the SMTPAppenderBase.setCharsetEncoding method is not public. I'd like to call it but to do that need either to extend or have a class in the same package which I don't really want. Do I miss something ? Cheers Andy

Remove appender from SiftingAppender
by Matthias Kretschmar 17 Mar '10

17 Mar '10

Hi @ all, I have an application handeling commands. Every command is created, executed and deleted at the end. For this, I use a SiftingAppender, with the commandId from the MDC as discriminator. As I understand the concept of the SiftingAppender, it creates a new Appender (in my case FileAppenders that write to seperate folders) for every command, that is created. So far, so good. Now I want to delete my command, inclusive its working directory with its logs. There I get a exception, that the directory cannot be deleted, because files are still in use. I assume, that the logfile cannot be deleted, because the Stream of the FileAppender still is open. Is there a possibility to close the stream. I would prefer a solution, where the FileAppender is closed or detached only by use of slf4j-api. But I believe, that I also have to use logBack in my source code. Until now, I succeeded getting the SiftingAppender, but I couldn't get the FileAppender. Matthias

opposite of ThresholdFilter or LevelRangeFilter available?
by Christian Migowski 16 Mar '10

16 Mar '10

Hi, does logback offer some functionality that can be thought of the opposite of the ThresholdFilter, i.e. I want an appender to log only events with levels BELOW and equal to the level specified. With log4j, there is the org.apache.log4j.varia.LevelRangeFilter available that can do such things, does something similar exists in logback? thanks in advance, regards, christian!

PatternLayout example not working (%PARSER_ERROR_)
by Eric Ortéga 13 Mar '10

13 Mar '10

Hi, I tried to use PatternLayout in my application, by mimicking the code in the Chapter 5 of the manual (http://logback.qos.ch/manual/layouts.html#ClassicPatternLayout) and kept getting this kind of errors : %PARSER_ERROR_message%PARSER_ERROR_n I ended up trying to compile the exact same code as in the manual and in the PatternSample.java example, still getting the same output. Looking into the sources gave me the idea to set the context of the layout, which indeed solved the problem : PatternLayout layout = new PatternLayout(); layout.setContext(rootLogger.getLoggerContext()); // <= ADDED THIS LINE layout.setPattern("%-5level [%thread]: %message%n"); layout.start(); Before that, I searched a solution to this problem on the net and didn't find anything relating to it, so I figured I should leave a message here in case it can help others... I don't know if the problem originates from a bug in logback or a mistake in the manual, so I post in the user list. I think it should get fixed, at least in the manual, though. Cheers, Éric

Hello, I have a question about MaxHistory. Logback version is 0.9.18 I think that behavior of MaxHistory is wrong in some circumstances. The similar behavior exists in the other thread, but I seemed to have not been resolved. e.g.) ・technical question ・urgent explination issue Also, it is not registered in JIRA. I test following cases. Could you confirm it? And could you tell me that its performance is normal? First, I set following xml files. ・<FileNamePattern>logFile.%d{yyyy-MM-dd-HH-mm}.log</FileNamePattern> ・<MaxHistory>2</MaxHistory> Second, I start the application in the following order. However, there is no log file in the log Directory. 1. I start the application at [2010-03-09 10:00] In the log Directory, ・logFile.log ...OK 2. I restart the application at [2010-03-09 10:01] In the log Directory, ・logFile.log ・logFile.2010-03-09-10-00.log ...OK 3.
