Subject RE: Re: Alternative naming convention for renaming files using RollingFileAppender
Date Tue, 12 May 2009 19:03:05 GMT

Hi Sarat,

The TimeAndSizeRollingAppender, available for free from www.simonsite.org.uk, is a custom
appender I put together to roll files by both time and by size. It adds the roll time into
the backup filename and adds an index if more than one backup file is produced during the
logging period. That's not quite your requirement but perhaps it might help?

This appender does some other stuff too, if configured appropriately; optionally zipping backups,
removing older backup files, and forcing file rolls at the end of a logging period rather
than waiting for the next log event before doing so.

HTH,

Simon
