OpenNMS Features

OpenNMS is an open source solution that helps you visualize and monitor everything on your local and remote networks. It offers comprehensive fault, performance, and traffic monitoring, and alarm generation in one place.

Highly customizable and scalable, OpenNMS easily integrates with your core business applications and workflows.

The OpenNMS platform monitors some of the largest networks in the Fortune 500, covering the healthcare, technology, energy, finance, government, education, retail, and industrial sectors, many with tens of thousands of networked devices. Able to handle up to 300,000 data points per second with flows, and configurable to handle more, OpenNMS meets the challenges of small and large-scale, enterprise network monitoring.

OpenNMS comes in two open source distributions: Horizon (community release) and Meridian (enterprise release). Additional components enhance the platform with distributed network monitoring (Minion), scalability (Sentinel), and scalable data persistence (Newts).

Beyond Horizon/Meridian, OpenNMS provides custom graph creation through Helm and a framework that uses artificial intelligence (AI) to group related network alarms for improved troubleshooting (ALEC).
