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"> <!--See also http://logback.qos.ch/manual/appenders.html#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!
