OpenText Network Node Manager i is a network management platform acquired by Micro Focus from Hewlett-Packard Enterprise, and now supported by OpenText.
[Micro Focus Network Node Manager i (formerly HP Network Node Manager)] is like you implement it, setup monitoring and alerting and forget it forever until any major activity is there and that is possible because of the product's stability. Another reason for product stability is less features as compared to other vendor tools and its own inbuilt database.
Most customers would like to see NNM get away from using some Java applets.
In environments where we see more than 10 different network device vendors in production, we see issues with L2 mapping. Different vendors use different L2 protocols. This can cause an issue with L2 discovery and mapping.
NNMi's user interface is described as well-designed and intuitive, making it easy for users to navigate and perform tasks quickly, thereby enhancing the overall user experience. The system offers a powerful network discovery mechanism that maps out your network's physical and virtual topology, enabling you to visualize connections between devices and identify potential issues. Fault monitoring is at its best. NNMi provides a unified environment for viewing faults, availability, and performance data, consolidating essential information into a single platform.
Support is long and arduous and often are unable to help resolve the issue. We often have to do escalations or duty manager to get things moved. Even with a technical account manager, we do not see much improvement from a support point of view. This is an area where Micro Focus has a lot of improvement to do.
NNMi is best suited for enterprise-grade, large to very large infrastructure. You have fewer servers to install the product and manage all your devices through a single server, which also enhances ease of use.
