Discovery process

The Network Manager discovery process produces a network topology that includes connectivity and containment data.

Discovery subprocesses
The discovery process consists of several subprocesses that work together to discover devices and device interconnectivity.
Discovery timing
Each full discovery consists of one or more discovery cycles. The division of a full discovery into multiple discovery cycles enables the discovery to complete in a timely way.
Discovery stages and phases
The discovery process can be divided into two stages: data collection and data processing. The stages are subdivided into phases.
Discovery cycles
A discovery cycle has occurred when the discovery data flow for a particular cycle has gone from start to finish. A full discovery might require more than one cycle.
Advanced discovery configuration options

Discovery process with EMS integration
Network Manager collects topology data from an EMS using collectors.
Rediscovery
When a discovery has completed, ncp_disco enters rediscovery mode, in which the discovery of new devices results in updates to the topology model.
