Large, distributed networks can be difficult to reach and monitor from a central location, with challenges like firewalls, network address translation (NAT) traversal, overlapping IP address ranges, and locked-down environments. The OpenNMS Minion component extends the reach of Horizon/Meridian, so you can monitor systems and networks that would otherwise be inaccessible, for optimal visibility into every [...]
When you want to store large amounts of non-aggregated data (such as performance metrics), the round robin database (RRDtool) in OpenNMS may not be enough. OpenNMS provides a time-series data store (Newts) that works with Apache Cassandra or ScyllaDB to group metrics for more efficient storage and retrieval. It removes aggregation as a bottleneck to storage, [...]
Based on Horizon 26.1.3, here’s a preview of some of the features we’re excited to bring to Meridian 2020: Enriched Flows, Better Messaging with Kafka Configure flows to include node metadata before forwarding to Kafka so that you can aggregate flow data or integrate it with your own custom database to persist all flows. New Kafka [...]
OpenNMS' automatic provisioning allows for rapid discovery and persistence of tremendous numbers of nodes, interfaces, and services. But what happens when device design prevents a customer from using automatic provisioning, and manual discovery would be tedious and time-consuming? You leverage OpenNMS' customizability and metadata DSL feature to discover those devices. The Customer: Windstream Windstream provides high-speed [...]
OpenNMS’ week-long annual IT conference, hackathon, and get-together for the global OpenNMS development community wrapped up Friday, July 31. Event Held in Minecraft The Covid-19 pandemic forced the normally in-person Dev Jam online, but with a twist. The event was held in Minecraft, customized with OpenNMS in mind. “OpenNMS has a community full of amazing people [...]

Presented by the TM Forum, a global industry association, catalysts are rapid-fire proof-of-concept projects that bring together large and small companies to create innovative solutions to common challenges, leveraging [...]
A good build environment needs the right balance among complexity, speed, cost, and adaptability. With our recent move to CircleCI, OpenNMS has achieved that balance and even created two customized tools that others might find useful.
Find out more about how using metadata in OpenNMS can streamline configuration.
No one wants to have a security vulnerability, particularly with network management software, where the consequences could be serious. Find out how OpenNMS deals with reported security issues when they arise.
If you are using the Prometheus toolkit to monitor your network systems, you can now integrate that performance data into OpenNMS with the new PrometheusCollector. Learn how.
