An appender is a node in the Management Console tree that uses log4j classes to define the output format of log information.
You can create appenders to log information in a format that is useful to your organization. You can use the built-in Rolling File, Syslog, SMTP, and SNMP appenders, or create a custom appender to store log information in any format. A logger can have multiple appenders.
Appenders are child nodes of logger nodes in the Management Console tree. Only administrators can create and edit appender nodes. An administrator cannot delegate appender permissions to a non-privileged user.
The Dynamic Data Masking system loggers use Rolling File appenders to create the rule.log, auditTrail.log, and server.log files. You cannot delete the system logger appenders. You can edit the system logger appender Max File Size and Max Backups properties, but you cannot edit the Type, Name, and File properties. You can add an appender to the system loggers to create an additional system log output.
