Requirements

This section describes the requirements to install the OpenNMS Plugin for Grafana.

Runtime requirements

For runtime operations, you need to install and set up either OpenNMS Horizon 33+ or Meridian 2024+. You also need a Grafana instance (version 12.x or newer).

We have tested the plugin with Grafana version 12.0. The plugin declares a minimum of Grafana 12.x, and Grafana does not load it on earlier versions. We recommend that you use matching versions of the plugin and Grafana (for example, OpenNMS Plugin for Grafana 12.x and Grafana 12.x).

The OpenNMS Grafana Dashboard Report feature requires the Grafana Image Renderer plugin to be installed.

Build requirements

To build the plugin, you must have Node.js installed (version 22.x or newer).

This is required only if you are installing the plugin from source.
