DiscoveredDevice Table

A DiscoveredDevice is a loose record of the discovery of a device on a network, using any of a number of discovery methods. As such, the same device may be found in more than one way (see DuplicateID which may be able to track this fact if known), or by more than one distinguishing feature. Accordingly this table has a somewhat unsatisfactory primary key!

Note: To cater for multi-tenant mode, this table may contain data for multiple tenants. Access requires that the database TenantID has been set in the SQL Server connection context information. That setting filters an underlying table to produce this view of data for the single, selected tenant.
