Each message category can be configured with one of the following log-levels:
none No access messages are included in the log file.
info Informational messages are included in the log file.
all All messages are included in the log file. In most cases, this setting produces the same results as the info setting. In certain situations, this setting enables additional debugging messages to be logged.
inherited The log level is inherited from the value of the default-log-level property.
By default, the log level for each message category is inherited but for SERVER_OP_DETAIL, the log level is none. As the default-log-level property is info, all the message categories except SERVER_OP_DETAIL inherits the log level info.
The log-level of a message category works in conjunction with the severity level of a message to determine which messages are included in the log file. For more information, see Message Severity.
