*
* DEBUG - Messages useful for debugging purposes.
* INFO - Informational messages. This is mostly information like
* 'disconnect was called' or 'SASL auth succeeded'.
* WARN - Warnings about potential problems. This is mostly used
* to report transient connection errors like request timeouts.
* ERROR - Some error occurred.
* FATAL - A non-recoverable fatal error occurred.
