OpenNMS Meridian vs. OpenText Network Node Manager i (NNMi)

Large network environments with few types of devices. The system is great but getting all of the MIBs loaded and to try and create unique rules /alarm type. Alarm correlation is doable but it takes too much manual work and XML configuration. I do enjoy the dashboard and surveillance categories.

[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.

• When we used OpenNMS you could download the base package for free and configure it fairly easily for your own environment. You can't beat that kind of price break.
• OpenNMS had a very nice looking GUI that was easily navigated and fairly straightforward to understand and configure.
• There were a wide variety of add-ons available for download and implementation.

Incentivized

• Network infrastructure monitoring.
• Interface monitoring.

• It takes a fair amount of experimentation to fine tune information collection.
• Configuration can be quite cumbersome with a steep learning curve. It would be nice if more of this could be done via the web dashboard.
• The reliance on Java will put some users off. However, in fairness, it does mean it runs on a wide variety of hardware.

• 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.

Although Grafana is in no way an alternative to OpenNMS's full functionality, it can be integrated with other solutions (including OpenNMS itself) to offer the graphing and data visualisation aspects of OpenNMS. In this regard, Grafana is more flexible, and some would say prettier, than OpenNMS's graphing. For the best of both worlds, I'd recommend using them both!

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.
