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
