When we started providing support for OpenNMS, we didn’t want to use the tired “per node” or “per license” method of pricing. “Per node” doesn’t scale for anyone but the vendor, and since all of our code is available under the GPL, the license model didn’t work either.

So we price our support per support contact. In the basic support subscription (the one you list for $4995) you get two contacts: a primary and a backup. They can manage as many OpenNMS instances as they want, and we encourage our clients to run a production as well as a development version.

Thus it makes it kind of hard to price per node. We have some clients with 100 devices, but we have one with nearly 50,000. Also, since we are client-less, the “work unit” is more along the lines of the number of interfaces and services being managed versus “nodes”. The 50K device client has about 66K interfaces whereas another client with only 12K devices has nearly the same amount of interfaces since their devices are mainly routers.

As a pure services company we try to price according to the number of people accessing our services versus how “much” OpenNMS a client uses.

Thanks again for including us and I hope this clarifies things a bit.

Tony: thanks for the note ;) I combined the concepts of “minimum” and “up to” to help normalize the table a little bit.

For the GroundWork pricing, the $8,000 annual number is for up to 50 devices monitored. It’s $16,000 annual for moniotring an unlimited number of devices (limited only by the performance capabilities of the monitoring server).
