The OpenNMS Group is here to make your OpenNMS experience painless and successful. Please feel free to contact us for deployment services and support.
OpenNMS is written mainly in Java, and thus it is supported on most operating systems. Each one has its own form of package management, so please choose the option that fits your hardware the best and install away.

For deb based distributions (Debian/Ubuntu) follow the instructions for adding the OpenNMS apt repository to the server.

What Our Clients Say
We are an ISP. Our network is what we actually sell, and that’s why we must have top performance from our network management system. We didn’t get top performance with our old system, but we do with OpenNMS. - Michael Micheletti, Manager of Engineering, TowerstreamRead More
In six hours, we had OpenNMS running with all the functionality that it had taken us three years to develop with Openview NNM. This was a rude but happy awakening. - Dale Meyerhoffer, Senior Network Analyst, Hershey Medical CenterRead More
I was the only IT person at the office, but with OpenNMS, it was easy to keep track of everything on the network, including our snow and ice-covered traffic light system. If there had been a problem, OpenNMS would have let me know. - John Jennery, City of Grapevine, TexasRead More
