When enabled, Simple DNS Plus will write all DNS queries and responses to a log file.

 

Select how often a new log file should be created.

 

To conserve disk space select how often the log files should be recycled (overwritten with new data).

Log files can grow very big very fast. Recycling them is a good way to conserve hard disk space.

 

If enabled, Simple DNS Plus will create additional "raw" log files of all incoming DNS requests.
This can be used to create domain / usage statistics and other purposes.

The Tools directory contains a command line tool to extract and filter raw log data and also a .NET programming library for accessing the raw log data.

See Raw log file format

 

Specify the directory where log files are written.

Just like with other log files, system performance can be enhanced by writing log files to different physical disk drive (other than where the operating system is installed).
NOTE: Do not use a network drive location for this - because the Simple DNS Plus service runs under the SYSTEM account and therefore does not have access to network shares.
