in rqt_logger_level, I see an rviz node, but there are no loggers within. Ideally I'm looking for a command-line switch that makes rviz spit out debug messages to the console.
I also tried adding the line log4j.logger.ros.rviz=DEBUG to the file pointed to by ROSCONSOLE_CONFIG_FILE, which has worked for nodes I launch, but not for rviz.
Not a full solution, but it should be possible to change the logger level at runtime with rqt_logger_level, but you won't be able to see debug messages at startup.
You may also want to try starting rviz with __name:=rviz to try to force it to use a non-anonymous name, which might make it pick up the proper logger configuration.
If you're developing plugins and you only want to see debug messages from your plugin, you can also use the ROS_DEBUG_NAMED() with your plugin name.

I think the issue is that rviz starts as an "anonymous" node, meaning it doesn't name collide with other "rviz" nodes. This is accomplished by changing the node name to
rviz_<random hexidecimal numbers>. Open an issue against rviz, it might be possible to add an option to rviz to make it happen.
