title: Is there a standard order for logging levels, from quiet to verbose?
body: <p>Many logging systems allow you to filter the logs by 'log level', where the levels are integers with names like 'DEBUG', 'INFO', and 'ERROR'.  My question is, is DEBUG always <strong>less than</strong> ERROR?  Or does this depend on the system?  I know there's no guarantee that a system follows the standard, but I'm just curious whether there is a mode of thinking that most logging systems adhere to?</p>
