OpenNMS was founded to unite the monitoring community with a highly effective, open source, vendor-neutral platform. The continued vibrancy of the platform relies on users like you: conversation, input, collaboration, and partnership of network monitoring professionals are what bring open-source solutions to life.

“OpenNMS has a large and active community of users and developers who are always willing to help, so I am never alone or helpless.”
