Re: [log4perl-devel] Log::Dispatch::FileRotate filename suffix

[John O. <joh...@o-...>]

It has this nifty feature built in, no need to write more code - see 
below....

 From my log4perl.conf file:

log4perl.logger.DataSite = DEBUG, DebugLog
log4perl.appender.DebugLog = Log::Dispatch::FileRotate
log4perl.appender.DebugLog.min_level=debug
log4perl.appender.DebugLog.max=10
log4perl.appender.DebugLog.DatePattern=yyyy-MM-dd
log4perl.appender.DebugLog.TZ=UTC
log4perl.appender.DebugLog.filename=/tmp/debug_log
log4perl.appender.DebugLog.mode=append
log4perl.appender.DebugLog.layout=PatternLayout
log4perl.appender.DebugLog.layout.ConversionPattern =[%d] [%P] %M(%p) - %m%n



The bit you want is DatePattern - it sets the pattern for the rotated 
files - in your case:

DatePattern=yyyyMMdd

When the evaluated version of that changes, it will do the rename and 
start a new file.
