Re: Enh rqst: a variation on DailyRollingFileAppender
Can you give details so I can determine if my appender has similiar problems?

There was some discussion and some code on MultiFileAppender back in October that was trying to address problems like having distinct log files per thread, but could also address some of the same issues as the RollingFileAppenders but without ever renaming files. However, I got distracted and haven't been able to get back to it. Search the archives if you are interested in the back story. -- James Staufferhttp://www.geocities.com/stauffer_james/ Are you good?

Re: Enh rqst: a variation on DailyRollingFileAppender
DateFormatFileAppender doesn't require you to use sub-directories. You are correct that it doesn't support groupings of hours (watches). Both DateFormateFileAppender and DailyRollingFileAppender use SimpleDateFormat so they only work for the patterns in that class. I suspect that your request is unique enough that it won't be added to log4j. You could easily create your own appender that does that. Look at DateFormatFileAppender for a sample of how to write your own appender.

If I set the pattern to 'logs'MMdd'.log' there will be just one logfile for the day. The comments in your source give a sample pattern that will create sub-directories for yyy, MM-MMM and dd-EEE. This is definately not what I want. IMO a smaller number of files and directories is perferable. But having only one file per day is not enough.
