Database catalog discovery The database catalog lists all the catalog objects, or databases, discovered for an instance of a database. Different database manufacturers use the term catalog differently. For example, MySQL uses database to mean catalog. Database catalogs can be imported into your instance from a third-party discovery tool, entered into the platform manually, or found by Discovery.Important: Discovery does not support Oracle or MySQL database catalog discovery in the base system. You must create probes and sensors to find these. To view a database catalog, navigate to Configuration > Database Catalogs and select a database.
