Only messages that have a level less than the current log object’s level will be logged. For example, if the log
object’s level is
\Slim\Log::WARN (5), the log object will ignore
but will accept
You can set the log object’s level during application instantiation, too:
<?php $app = new \Slim\Slim(array( 'log.level' => \Slim\Log::WARN ));
