Hi, The stock grafana worldmap-panel allows data points to be displayed as circles of different sizes and colours on a world map. Unfortunately the original panel needs the data coordinates to be supplied as a geohash string which the OpenNMS data source cannot provide.
Without modifying the OpenNMS data source, I have forked the Grafana world map plugin and added the ability for it to work with latitude and longitude values from the OpenNMS Data source. Applications for this feature are for instance showing wifi access point power levels in a map of the wifi points or plotting pollution measurements collected from geographically dispersed IoT sensors. This version of the worldmap-panel requires each data value which is to be rendered as a circle to also have latitude and longitude values in the time series. This can be easily achieved by adding a simple XML data collection service into the OpenNMS configuration which reads the latitude and longitude for a node from the asset table. See https://github.com/gallenc/worldmap-panel See also documentation at https://github.com/gallenc/worldmap-panel/blob/master/OpenNMS_Datasource.md Please give it a try. Feedback welcome. Craig
