What The OpenNMS Group does
The OpenNMS Group, Inc. is a North Carolina-based software company (wholly owned subsidiary of NantHealth, Inc., NASDAQ: NH) that publishes and commercially supports the OpenNMS network monitoring platform, originally created in 2000 as the world's first fully open source enterprise-grade network service monitoring system under the AGPLv3 license. The platform combines fault management, performance monitoring, and network traffic analysis in a distributed Java/Karaf architecture, with Minion (remote/poller) and Sentinel (horizontal data-processing) components enabling deployments that scale to tens of thousands of devices and over 300,000 flows per second, as validated by customers including New Edge Networks (160,000+ interfaces) and CityFibre (UK fiber operator). The company sells to telecommunications carriers, large enterprises, healthcare providers, and government/municipal organizations across North America, EMEA, LATAM, and Southeast Asia through a multi-channel model that combines direct sales, VARs (Avendis, Ni2, nSpectrum, Daitek), resellers (triOLOGY, SHI, PCS), and PoweredBy/OEM partners (Hewlett Packard, Cisco, Corvit).
The commercial product, OpenNMS Meridian, is delivered as a tiered annual subscription (Basic at $6,000 per year to Premier+ at custom pricing) with add-on managed deployment, resident engineering, and 24/7 emergency support services, while OpenNMS Horizon is offered as a free community edition downloadable from GitHub and serves as the top-of-funnel for community-led adoption. Recent platform investment has been directed at ALEC (an ML-based alarm correlation framework), the Prometheus RemoteWrite Plugin (supporting Cortex, Mimir, Thanos, and VictoriaMetrics backends), and integration with Grafana, ServiceNow, VMware, and ITSM platforms — signaling strategic intent to remain compatible with cloud-native observability stacks while preserving the on-premises strengths that anchor the install base. The company has limited direct sales headcount (1-10 employees) and relies on its channel and community ecosystem for go-to-market reach, generating revenue from subscription, professional services, and OEM/white-label licensing economics that are consolidated within NantHealth's public reporting.

The OpenNMS Group competitors and assessment
Company assessmentBroad incumbents
- New Relic:
- SolarWinds: SolarWinds is a broad incumbent in IT operations management with NPM, SAM, and a full suite of network and infrastructure monitoring products. It competes with OpenNMS in the enterprise segment with a much larger product portfolio and commercial reach, including hybrid observability offerings.
- Splunk (Cisco): Splunk (now owned by Cisco) is a broad incumbent in observability and SIEM, with infrastructure monitoring capabilities. Its acquisition by Cisco creates additional overlap with OpenNMS's Cisco relationship and positions it as a unified IT operations competitor.
- Dynatrace: Dynatrace is an enterprise observability and APM platform with infrastructure, network, and application performance monitoring. It competes with OpenNMS for large enterprise IT budgets and increasingly bundles network monitoring into AI-driven full-stack observability offerings.
- Datadog: Datadog is a leading cloud-based observability platform covering infrastructure monitoring, APM, logs, and network performance (including its Network Performance Monitoring product). It competes with OpenNMS for enterprise IT operations budgets, particularly as buyers consolidate on unified observability suites.
Emerging players
- LibreNMS: LibreNMS is a community-driven open-source network monitoring platform with auto-discovery, alerting, and broad device support. It is a free alternative to OpenNMS Horizon, competing for the same community-driven adoption funnel and emerging as a viable open-source replacement.
Direct peers
- Paessler PRTG: PRTG is a commercial network monitoring platform focused on sensors-based infrastructure, applications, and cloud monitoring. It is a direct competitor in the mid-market and enterprise network monitoring space, with similar use cases around fault, performance, and bandwidth monitoring.
- Nagios: Nagios is one of the most established open-source network monitoring platforms (Nagios Core) with commercial offerings (Nagios XI, Nagios Log Server). It overlaps directly with OpenNMS in SNMP-based monitoring, alerting, and infrastructure observability, and competes for the same IT operations buyer.
- Checkmk: Checkmk (formerly Check_MK) is an open-source IT monitoring platform from tribe29 with both a free Raw edition and an enterprise edition, similar to OpenNMS's Horizon/Meridian model. It competes directly in network and server monitoring for mid-market and enterprise customers.
- Zabbix: Zabbix is an open-source enterprise network and application monitoring platform with a similar enterprise + free community model. It competes head-to-head with OpenNMS in fault and performance monitoring, supports similar protocols (SNMP, IPMI, JMX), and targets the same mid-to-large enterprise buyers.
