OpenNMS Meridian is a highly scalable open source 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.

Meridian scales up for enterprise

Meridian 2024 delivers upgraded support for enterprise-scale network monitoring. This release features robust technical upgrades with user-friendly enhancements that empower you to manage a vast network infrastructure more efficiently and securely than ever.

Updates include future-proof support for Java updates, enabling faster execution, improved security, and better resource management. The revamped structured node list streamlines device troubleshooting and maintenance. The shift to RedHat’s Universal Base Image smooths containerized deployments, and upgrades for Cassandra data storage improve flexibility, performance, and stability. Finally, whether you’re predicting network traffic patterns or anticipating resource demands, the adoption of native Holt-Winters forecasting enhances your predictive monitoring capabilities.

With these updates, your enterprise network becomes drastically less complicated to monitor and manage. You can focus on tackling your next project or initiative instead of tweaking and tuning existing operations. From deployment to network-wide management—Meridian is your scalable enterprise network monitoring solution.

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.
