3.3.3 Checking discovery progress
After initiating the spiral discovery process, verify that the process is running correctly.
- Note
Because spiral discovery is dynamic, NNMi discovers network nodes on a continuous basis. Whenever a new node is added to a discovery rule, NNMi discovers the node, collects topology information about the node, and begins to monitor the node.
There are several ways to gauge discovery progress. Perform any of the following actions to check the discovery progress:
During discovery, check the status of seeds by using Configuration > Discovery > Seeds. Review the status information in the Discovery Seed Results column. When discovery is nearing completion, the majority of the nodes have the Node created status.
During discovery, check the discovery progress by using Help > System Information, and then click the Database tab. Check the Database Object Counts several times during a one-hour period. The numbers in the Nodes, SNMP Agents, Interfaces, IP Addresses, and L2 Connections fields will stabilize. If these numbers are no longer increasing in value over the sampling period, then discovery is complete.
During discovery, from the NNMi console, in the Inventory workspace, select Nodes. Check the value in the Total field several times during a one-hour period. If this number is no longer increasing in value over the sampling period, then discovery is complete.
During discovery, from the NNMi console, check the discovery progress by clicking Tools > NNMi Self-Monitoring Graphs > Discovery Progress.
During discovery, from the NNMi console, check the discovery progress by clicking Tools > Status Distribution Graphs > Node Status.
During discovery, from the NNMi console, in the Topology Maps workspace, click Network Summary. Watch the map grow in complexity during a one-hour period. If the map growth slows and then stops over the sampling period, discovery is complete.

If you suspect a problem with discovery, see (3) Problem: NNMi is not discovering nodes.
