Rolling File appenders create plain text output files. You can use any plain text extension, such as .log or .txt.

The File property contains the file path and name of the log file. If you do not specify a complete file path, the path originates in the Dynamic Data Masking installation directory. For example, the rule.log file has the following File property:

log\rule.log

The Max File Size and Max Backups properties prevent the log files from becoming too large. When the log reaches the Max File Size, the logger creates a new log file. When the number of files exceeds the Max Backups number, the logger overwrites the first log file that it created. You can specify Max File Size and Max Backups in megabytes or gigabytes by entering the number followed by MB or GB. Do not insert a space between the value and the unit of measure.
