Get OpenNMS

This is the Download Page!

Occasionally we get calls from people who hit the “Download Now” button, which brings them to this page and they end up scratching their heads since “nothing happened”.

Well, OpenNMS is supported on so many platforms that we don’t have a system (yet) to automatically download and start using the application. Thus you have to read this page and go to the tutorial referenced below to download OpenNMS for your platform.

Downloading OpenNMS

Due to the size, power and complexity of OpenNMS, there isn’t a “one click” download available. Please follow the instructions below to get the right software for your system.

Current Release Version

The current release is 16.0.3 (release notes).

If you wish to install a development snapshot of future releases, see the “Choosing a Release” section of the tutorial for details.

Download and Install

To get started installing OpenNMS, check out the OpenNMS Tutorial. It will tell you everything you need to know about downloading the correct packages for your platform, installing OpenNMS, as well as walking you through basic configuration.

Get the Mobile Client

OpenNMS Compass is a modern mobile iOS and Android client for OpenNMS® Horizon™ and OpenNMS® Meridian™ servers.

It provides a simple dashboard for viewing outage and alarm data, node details, and more.
