If the modules use stealth logging,

package MyPackage;
use Log::Log4perl qw(:easy);
sub method {
    DEBUG "Doing something!";
}
[download]

How does the main driver turn debugging on an off?

use Log::Log4perl qw(:levels);
Log::Log4perl->init("/home/mycode/log4perl-conf.txt");
my $logger = Log::Log4perl->get_logger;
$logger->level($DEBUG);
[download]

is not "seen" by the module.

Or am I just not getting it by trying to set levels in my code, rather than in the conf file? I don't envision using the 'change logging level while code is running' feature, and it seems more direct to me to set the log level in the code, rather than in the conf file. I'm really just using the conf file for appender & filter specification, it seems.

Thanks for any clarification. Mike, your advice has been great, thanks.
