Answer: Foxhound is two products in one: it is both a database monitor and a schema troubleshooter for SQL Anywhere.

A database monitor is a computer program that measures the activity of a database management system and displays those measurements in a meaningful way, so that you can easily see that everything's OK or quickly learn about problems and threats to performance and availability. A monitor can also send email alerts when something goes wrong.

A schema troubleshooter is a computer program that performs a static analysis of the tables, columns, indexes, foreign key relationships and other objects in the database, displays those objects in a way that's easy to understand and easy to navigate, together with various facts, figures and curiosities which may be problems that need attention.
