All Implemented Interfaces:

org.apache.log4j.Appender, org.apache.log4j.spi.OptionHandler

public class DailyFileAppender
extends org.apache.log4j.FileAppender

Special log appender for log4j. Adds the current date (ie. year-mon) to the end of the file name, so that rolling on to the next log is simply a case of starting a new one - no renaming of old logs. This is advisable if you are using Windows, and have multiple applications (ie. dspace, dspace-oai, dspace-sword) that all want to write to the same log file, as each would otherwise try to rename the old files during rollover. An example log4j.properties (one log per month, retains three months of logs) log4j.rootCategory=INFO, A1 log4j.appender.A1=org.dspace.app.util.DailyFileAppender log4j.appender.A1.File=@@log.dir@@/dspace.log log4j.appender.A1.DatePattern=yyyy-MM log4j.appender.A1.MaxLogs=3 log4j.appender.A1.layout=org.apache.log4j.PatternLayout log4j.appender.A1.layout.ConversionPattern=%d %-5p %c @ %m%n
