Logging - Level

Standard

syslog (RFC5424) specifies that the order of severity is assumed to be numerically ascending from most important to least important.

Example: logging levels are prioritized from 0 to 6 (highest to lowest):

const levels = { 
  error: 0,
  warn: 1,
  info: 2,
  http: 3,
  verbose: 4,
  debug: 5,
  silly: 6
};
