At a glance, the code in your conf file looks good. I think you're being bitten by another issue -- basically, whenever Log4perl sends a message off to your newpingdata Logger, it additionally will give that message to every other logger in the heirarchy, including your rootLogger.

The exact problem and solution were discussed in-depth, including examples, in this node on Log4perl. To summarize, you can tell a logger not to send messages up the heirarchy using additivity. You can also tell a given appender not to accept log messages below a certain log level by using threshold. And of course, there are filters and other goodies, but I don't think you need to go that far for your current problem.

So, check out the above node, and also look up those terms in Log4perl's documentation. Good luck!

    And that is why recently I started to not even have a root logger - to avoid the double logging that you mention.
    I did this as an experiment with some code I am writing now - and it seems to work fabulously well
    # set your logger here # Note - no root logger - this is not always what you want # but at this early stage of developement, is good enough #log4perl.logger=INFO, A1 log4perl.logger.WSR_Generator._create_wsr_document=INFO, A1 #log4perl.logger.WSR_Utils.form_order=DEBUG, A1 #log4perl.logger.WSR_New_Worker_Return.create_wsr_records=DEBUG, A1 #configure SCREEN logger log4perl.appender.A1=Log::Dispatch::Screen log4perl.appender.A1.min_level=debug log4perl.appender.A1.stderr=1 log4perl.appender.A1.layout=Log::Log4perl::Layout::PatternLayout log4perl.appender.A1.layout.ConversionPattern=%d %-5.5p - %M - %m%n
