Adjust log level of python logger in a library (pyactiveresource)

My logging was being polluted by pyactiveresource that was writing a lot of useless logs at the 'INFO' level. I wanted my own logging set at INFO, so how can you change pyactiveresource? As described in the python doco, you can access the logger with getLogger and adjust the level like this:

  noisy_logger = logging.getLogger('pyactiveresource')
  noisy_logger.setLevel(logging.WARN)

Then just set your own logger as normal, something like:

  syslog = logging.handlers.SysLogHandler('/var/run/syslog')
  syslog.setFormatter(logging.Formatter('%(name)s: %(message)s'))
  syslog.setLevel(logging.INFO)
  logging.getLogger().addHandler(syslog)
