     * debug levels:
     * error - Runtime errors or unexpected conditions. Expect these to be immediately visible on a status console. See also Internationalization.
     * warn  - Use of deprecated APIs, poor use of API, 'almost' errors, other runtime situations that are undesirable or unexpected, but not necessarily "wrong". Expect these to be immediately visible on a status console. See also Internationalization.
     * info  - Interesting runtime events (startup/shutdown). Expect these to be immediately visible on a console, so be conservative and keep to a minimum. See also Internationalization.
     * debug - detailed information on the flow through the system. Expect these to be written to logs only.
