The OpenNMS Group

Here is The OpenNMS Group in plain terms. OpenNMS® Horizon is the world's first enterprise grade network management platform published under the open source model. The job it does: connecting machines, sensors and robots to software that controls or monitors them.

The natural audience is manufacturers and operators. Related areas on their profile: Consulting, Internet of Things and Robotics. As a very small product team themselves (1 to 10 people), they tend to serve customers of a similar scale best. You will probably talk to the people who build it, which is great until you need 24/7 support.

The OpenNMS Group is based in Pittsboro, North Carolina. More on opennms.com.

Things worth asking about: hardware compatibility, uptime, and support. Ask for a trial on your own data, not a canned demo.
