Hello, I'm new to logback but read your documentation, I an not receiving any output to my logfile. Here is my configuration file, following this is the output from logback to the console. The only thing I notice is a warning about a TriggerPolicy. If this is the case do you have example syntax? --- <?xml version="1.0" encoding="UTF-8"?> <configuration> <appender name="bitranlog" class="ch.qos.logback.core.rolling.RollingFileAppender"> <param name="append" value="true"/> <param name="MaxBackupIndex" value="1"/> <param name="file" value="/tmp/bitran.log"/> <param name="MaxFileSize" value="5MB"/> <layout class="ch.qos.logback.classic.PatternLayout"> <param name="pattern" value="%d [%-15.15t] %-5p %-30.30c{1} - %m%n"/> </layout> </appender> <logger name="org.accma.concentrator.services.bitran.BiTranService" additivity="false"> <level value="debug"/> <appender-ref ref="bitranlog"/> </logger> <root> <level value="debug" /> <appender-ref ref="bitranlog" /> </root> </configuration> --- Here is console output when using LoggerStatusPrinter: --- startElement [configuration] startElement [appender] startElement [param] startElement [param] LOGBACK: No context given for ch.qos.logback.core.util.PropertySetter@8c5ea2 startElement [param] startElement [param] LOGBACK: No context given for ch.qos.logback.core.util.PropertySetter@198defc startElement [layout] startElement [param] startElement [logger] startElement [level] startElement [appender-ref] startElement [root] startElement [level] startElement [appender-ref] INFO in ch.qos.logback.classic.joran.action.ConfigurationAction - Ignoring debug attribute.
