The current default log level is INFO, but I propose that we change it to WARN.
- WARN Usual level, anything that is printed is interesting every time you see it
- INFO Extra verbosity if you are feeling nosy or something's odd (i.e. the first layer of added verbosity)
- DEBUG The sort of thing that you only need if you're willing to wade through a lot of semi-random information
- TRACE Even more material, but now specific to different sub-systems.
If you consult https://docs.python.org/2/howto/logging.html, "When to use logging” section you'll note that "The default level is WARNING" and INFO means, "Confirmation that things are working as expected".
