The date, log-level, messages will be output with pipe delimiter in server.log.
This log-level will be the setting for defining the basis of the information displayed in the log-file and depending on the settings of log-level, the amount of information output to the log file will be different.
(Default is "FINFO".)
As an example, if log-level is made to "INFO", then the log-level which is the output target, will be "FATAL" "ERROR" "NOTICE" "WARN" "INFO" and "FINFO" etc., cannot be displayed.
For details on log-level types and output content, specifying place, refer to the online help using Reference Information URL.
