  link:http://grafana.org/[Grafana] provides an API key which gives access for 3rd party application like _OpenNMS_.
  The _Grafana Dashboard Box_ on the start page shows dashboards related to _OpenNMS_.
  To filter relevant dashboards, you can use a _Tag_ for dashboards and make them accessible.
  If no _tag_ is provided all dashboards from _Grafana_ will be shown.
  
  The feature is by default deactivated and is configured through the `opennms.properties`.
