Logging solution

[pan261]

On top of graylog, we probably want an internal logger that has a bit more customization than console.log()

[pan261]

We can have more detailed logs in a log file, while outputting simple logs in the console

[pan261]

Using winston js as our logger, with outputs to both console and a log file.

Notes:

• To use the logger, use logger.info('message', {object})
  • logger.info can be replaced with logger.warn, logger.error, or logger.debug
  • Formatting of messages should be "file: log message"
    • winston does not get caller function name or file name for performance reasons, so we just manually prepend the filename for all logs.
  • The object can be any object, a response, error, etc.

connect to graylog

Winston logging is done, we will probably not want to send all of the logs to graylog, so we need to figure out which logs we want to send
