Grafana Dashboard Box
Horizon uses Grafana to generate visualizations, including those displayed in the Grafana Dashboard Box.
Filter dashboards
To filter for relevant dashboards, you can use a dashboard’s tag (defined by the org.opennms.grafanaBox.tag property) and make it accessible.
If no tag is provided, all Grafana dashboards are shown.
You can configure this feature by creating or editing ${OPENNMS_HOME}/etc/opennms.properties.d/grafana.properties and setting the configuration properties.
