Network Node Manager i (NNMi) is a program that helps a network administrator view and manage the conditions in a computer network. NNMi is part of the OpenView suite of enterprise system management applications from HPE (Hewlett-Packard Enterprise), the company's business products and services division.
Using Network Node Manager i, an administrator can view the network in an easy-to-see graphical format. NNMi "discovers" the devices that are in the network and shows their relative location and their status. When a device fails, NNMi can analyze events associated with the failure and help to recommend action. NNMi also provides some predictive information that helps identify potential failures before they occur.
