Meridian
OpenNMS Meridian is a highly scalable network management platform with network traffic analysis, network discovery, alerting, and monitoring.
It's a comprehensive solution to monitor enterprise network performance and ensure the availability and performance of your critical network services.

Modern Design Meets Powerful Integration
Meridian 2025 delivers a fresh, modern experience designed to make network management faster and more intuitive. The redesigned horizontal interface streamlines navigation, reduces clicks, and organizes workflows into clear modules, giving users a cleaner, more efficient way to manage complex environments. This update reflects our commitment to usability and innovation, ensuring teams can accomplish more with less effort.
Beyond the UI, Meridian 2025 introduces powerful enhancements that boost flexibility and integration. Support for Elasticsearch 8.x and composable templates enables advanced customization, while the new ServiceNow plugin simplifies ITSM connectivity for smoother operations. Additional improvements include virtual appliance options for easier deployment, expanded security features, and key performance upgrades—all driven by customer feedback. Together, these updates position Meridian as a smarter, more adaptable solution for evolving network needs.


OpenNMS does a better job of helping us manage our network, and requires less of our time to do it.

Features & benefits
Cloud-hosted time series
Optimized for OpenNMS metric collection and streaming telemetry, Time Series DB is a cloud service that provides everything you need to store and persist your performance metrics without maintaining software, managing hardware, or underutilizing resources.
Containerized Meridian
Reduce complexity for your container-centric environments. Deploy Meridian on Red Hat OpenShift—or your container platform of choice—to get the power and flexibility you need, without the overhead of traditional hardware and VM provisioning.
Zero-trust with Minions
OpenNMS Minion is an optional component that enables OpenNMS to monitor devices and services in locations that it otherwise cannot reach. OpenNMS Minions can collect monitoring data at remote protected networks—even when those networks are not Zero-Trust compliant—and then repackage and transmit that data to the OpenNMS Core using Zero-Trust principles by enabling TLS for communications to the OpenNMS Core and Kafka or ActiveMQ.
Custom NetFlow thresholding
Quickly analyze your flow data against threshold computations to detect and alert you to anomalies and changes in your network environment. Ensure network health and identify bandwidth-related issues, even as flow volumes increase.
Device configuration backup
Store and manage configurations for network devices, no matter how remotely distributed, natively within Meridian. Schedule automated config backups—or initiate as needed with a single click—view backup history, and compare configurations over time to address issues.
Plugin development API
Our official plugin API provides a stable base to extend the configuration of Meridian, consume its outputs, and expose expanded functionality. Get the flexibility you need in monitoring—build, validate, and assure compatibility with future Meridian releases.
