log4j with timestamp per log entry

Question

this is my log output

INFO main digestemails - process inbox
INFO main digestemails - checking for emails in c:developmentDCMailemailKN-Source
INFO main digestemails - digesting [email protected]
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.

You can find more conversion characters usage in log4j javadoc.For example, at http://logging.apache.org/log4j/1.2/apidocs/org/apache/log4j/PatternLayout.html.

A extract from my properties file

log4j.rootLogger=INFO, stdout, logfile

log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%d %p (%t) [%c] - %m%n

log4j.appender.logfile=org.apache.log4j.RollingFileAppender
log4j.appender.logfile.File=C:/log/client.log
log4j.appender.logfile.MaxFileSize=5MB
log4j.appender.logfile.MaxBackupIndex=0
log4j.appender.logfile.layout=org.apache.log4j.PatternLayout
log4j.appender.logfile.layout.ConversionPattern=%d %p [%c] - %m%n
