In my log4perl config file I have a very simple screen appender.

log4perl.appender.screenAppender = Log::Log4perl::Appender::Screen
log4perl.appender.screenAppender.utf8     = 1
log4perl.appender.screenAppender.layout =
Log::Log4perl::Layout::PatternLayout
log4perl.appender.screenAppender.layout.ConversionPattern \
   = [%d{E MMM dd HH:mm:ss yyyy}] [%p] .......



Sometimes my Catalyst app runs under mod_perl2 and so I'd like to try using
the Log::Dispatch::ApacheLog[1] appender *instead* of the Screen appender.


1) Is there a way in the config to optionally select appenders?   Or would
it just be better to have more than one log4perl config file and select the
file at start (e.g. by specifying which log4perl file to use at startup)?

2) Perhaps a question for another list, but the ApacheLog appender wants a
"$r", which the docs say is an Apache or Apache::Server object.
 Something like this?

log4perl.appender.screenAppender = Log::Dispatch::ApacheLog
log4perl.appender.screenAppender.apache = sub { Apache2::ServerUtil->server
}


I assume setting utf8 is specific to the appender, right?

3) Do I need to use Log::Log4perl::Appender::Synchronized with Apache?   In
my testing with the Screen appender messages < 4K are always written to the
logs atomically -- anything larger then I can get mixing of log entries
from different processes.

Thanks,


[1] The reason would be to have a unified format for both app log entires
and any messages Apache generates.
