actually there is some filtering ability available in the normal properties file, probably enough for you needs:
log4j.appender.MyAppender.Threshold=INFO Cheers Adrian -----Original Message----- From: Kevin Dougan [mailto:[EMAIL PROTECTED] Sent: 09 October 2003 05:16 To: Log4J Users List Subject: RE: log4j.properties - How to parse outpu to multiple files Eureka! I have a solution! I now have my logging messages split out into the 4 types that I support: DEBUG, INFO, WARN & ERROR. My app-debug.log file contains everything, down to my app-error.log file which only contains errors! Why is it that these moments tend to occur after midnight... :-) Note: I switched from log4j.properties to log4j.xml in order to take advantage of filters, which aren't supported in the properties file. Here's my log4j.xml file, enjoy: <?xml version="1.0" encoding="UTF-8" ?> <!DOCTYPE log4j:configuration SYSTEM "log4j.dtd"> <log4j:configuration xmlns:log4j='http://jakarta.apache.org/log4j/'> <appender name="STDOUT" class="org.apache.log4j.ConsoleAppender"> <layout class="org.apache.log4j.PatternLayout"> <param name="ConversionPattern" value="%c %d{ISO8601} -- %p -- %m%n"/> </layout> </appender> <appender name="DEBUG" class="org.apache.log4j.RollingFileAppender"> <param name="File" value="C:\\logs\\app-debug.log"/> <param name="Append" value="true"/> <param name="MaxFileSize" value="500KB"/> <param name="MaxBackupIndex" value="2"/> <layout class="org.apache.log4j.PatternLayout"> <param name="ConversionPattern" value="%c %d{ISO8601} -- %p -- %m%n"/> </layout> </appender> <appender name="INFO" class="org.apache.log4j.RollingFileAppender"> <param name="File" value="C:\\logs\\app-info.log"/> <param name="Append" value="true"/> <param name="MaxFileSize" value="500KB"/> <param name="MaxBackupIndex" value="2"/> <layout class="org.apache.log4j.PatternLayout"> <param name="ConversionPattern" value="%c %d{ISO8601} -- %p -- %m%n"/> </layout> <filter class="org.apache.log4j.varia.LevelRangeFilter"> <param name="LevelMin" value="INFO" /> </filter> </appender> <appender name="WARN" class="org.apache.log4j.RollingFileAppender"> <param name="File" value="C:\\logs\\app-warn.log"/> <param name="Append" value="true"/> <param name="MaxFileSize" value="500KB"/> <param name="MaxBackupIndex" value="2"/> <layout class="org.apache.log4j.PatternLayout"> <param name="ConversionPattern" value="%c %d{ISO8601} -- %p -- %m%n"/> </layout> <filter class="org.apache.log4j.varia.LevelRangeFilter"> <param name="LevelMin" value="WARN" /> </filter> </appender> <appender name="ERROR" class="org.apache.log4j.RollingFileAppender"> <param name="File" value="C:\\logs\\app-error.log"/> <param name="Append" value="true"/> <param name="MaxFileSize" value="500KB"/> <param name="MaxBackupIndex" value="2"/> <layout class="org.apache.log4j.PatternLayout"> <param name="ConversionPattern" value="%c %d{ISO8601} -- %p -- %m%n"/> </layout> <filter class="org.apache.log4j.varia.LevelRangeFilter"> <param name="LevelMin" value="ERROR" /> </filter> </appender> <root> <priority value="debug"/> <appender-ref ref="STDOUT"/> <appender-ref ref="DEBUG"/> <appender-ref ref="INFO"/> <appender-ref ref="WARN"/> <appender-ref ref="ERROR"/> </root> </log4j:configuration> -----Original Message----- From: Kevin Dougan Sent: October 8, 2003 3:09 PM To: [EMAIL PROTECTED] Subject: log4j.properties - How to parse outpu to multiple files Greetings log4j list! I'd like my logging output to be sent to multiple files at once. However, I only want ERRORs in the app-error.log file, DEBUG in the app-debug.log file, etc. As a potential compromise, I would be OK if I was able to at least reduce the types of log messages as the severity increased. Can anyone assist with my log4.properties file? I've included a copy below, but note that this config sends all the logging output to all files. In addition, is there a way to avoid all the duplication in this config file, so I just have to change the name of the output file in each case, and inherit all the RollingFileAppender settings as I define each file?
