You can add logger nodes in the Management Console tree under the Loggers node.

Use loggers to specify the events that you want to log and use appenders to define how to log the event. You can use pre-defined system loggers to log Dynamic Data Masking Server, service, and rule events. You can create custom loggers to log security rule events that you specify with the Log Message rule action.

Logger nodes can have multiple appender child nodes. When you use the logger in a security rule, the logger logs the event in each format specified by the child appender nodes.

Dynamic Data Masking contains pre-defined system loggers and appenders that log Dynamic Data Masking service events and rule events. You cannot edit or delete the system loggers.

The Loggers node is a child of the Dynamic Data Masking Server node in the Management Console tree. Because it is a child of the Dynamic Data Masking Server node, only Dynamic Data Masking administrators can edit and create child nodes of the Loggers node. Non-privileged users cannot edit or move logger and appender nodes and an administrator cannot delegate permissions to a non-privileged user.
