Choosing a network monitoring platform means weighing open-source flexibility against enterprise scale, and vendor lock-in against cost predictability. This buyer's guide breaks down nine of the leading platforms, framed around the five factors that matter most: openness, enterprise scalability, flow visibility, protocol support, and value. Get side-by-side comparisons, key strengths and trade-offs for each tool, and a quick-reference chart to help you match a platform to your environment.

Explore the challenges in effectively monitoring distributed network environments—and solutions to address those challenges. See what a distributed monitoring solution can do for your business.

Join Marshall Massengill, principal solutions delivery architect at OpenNMS, as he explains the concepts of network flows, SNMP and how OpenNMS Meridian integrates both to deliver a robust network monitoring solution. The webinar showcases OpenNMS Meridian as not just a monitoring tool, but a strategic asset for businesses, ensuring their networks are not only healthy and secure but also well-prepared for future growth and challenges.

The security implications of a network monitoring solution extends beyond the installation of the platform itself. This reference architecture presents the structural components of the OpenNMS monitoring software and the security implications, guidelines, and best practices for using them.

Meridian includes the most stable and secure features from Horizon, our community release distribution. Meridian is much easier to maintain and use without the headache of rapid upgrades and releases, and it is supportable long term.

A Minion is a lightweight stateless service that enables OpenNMS to communicate with devices and services in hard-to-reach locations.

OpenNMS Minion Virtual Appliance makes it easier to deploy, configure, and manage Minions through a cloud-enabled service, accessible from anywhere.

The Sentinel component provides dynamic scalability for data processing, including flows, SNMP traps, syslog messages, and streaming telemetry.

OpenNMS Plugin for Grafana (formerly known as Helm) is an application for creating flexible dashboards to display and customize fault management and performance management data from Horizon and Meridian.

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