Question

this is my log output

INFO main digestemails - process inbox INFO main digestemails - checking for emails in c:\development\DCMail\email\KN-Source INFO main digestemails - digesting [e-mail] INFO main digestemails - extracting attachments INFO main digestemails - no attachments or no attachments supported INFO main digestemails - updating database INFO main digestemails - email -> COMPLETED folder INFO main digestemails -   

I would like a time stamp per log message ie

INFO 2008-12-25 13:14:00 digestemails - email -> COMPLETED folder 

here is my log4j config file

log4j.rootLogger=debug, stdout, R  log4j.appender.stdout=org.apache.log4j.ConsoleAppender log4j.appender.stdout.layout=org.apache.log4j.PatternLayout  # Pattern to output the caller's file name and line number. log4j.appender.stdout.layout.ConversionPattern=%5p [%t] (%F:%L) - %m%n  log4j.appender.R=org.apache.log4j.RollingFileAppender log4j.appender.R.File=c:\\development\\DCMail\\logs\\digestlogfolder\\digest-logfile.log  log4j.appender.R.MaxFileSize=100KB # Keep one backup file log4j.appender.R.MaxBackupIndex=1  log4j.appender.R.layout=org.apache.log4j.PatternLayout log4j.appender.R.layout.ConversionPattern=%p %t %c - %m%n  

How do I do it?

Answer 1

Use %d in your PatternLayout.

Also %d can take a format pattern as in %d{dd MMM yyyy HH:mm:ss,SSS} you can pick and choose the elements that you want. When the format pattern is omitted the date will be in ISO8601 format.
