Discovery databases

There are various specialized databases that are used by ncp_disco, the component that discovers network device existence and connectivity, and by ncp_model, the component that manages, stores, and distributes the discovered network topology.

The ncp_disco component and ncp_model component store configuration, management, and operational information in databases. You can interrogate these databases by logging into the DISCO or MODEL service using the OQL Service Provider.

The ncp_disco databases can either be active or passive. When data is inserted into an active database, an action is automatically triggered; for example, another table is populated with data, or a script or stitcher is launched.
