log4j with timestamp per log entry
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 [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
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.
