LOG_LEVEL

LOG_LEVEL_NAME Description fatal The service/app is going to stop or become unusable now. An operator should definitely look into this soon. error Fatal for a particular request, but the service/app warn A note on something that should probably be looked at by info Detail on regular operation. debug Anything else, i.e. too verbose to be included in info trace Logging from external libraries used by your app or very detailed application logging.

Setting a logger instance (or one of its streams) to a particular level implies that all log records at that level and above are logged. E.g. a logger set to level "info" will log records at level info and above (warn, error, fatal).
