I don't have Internet connection on my terminal (OS-Ubuntu). Therefore I copied 'grafana-worldmap-panel' plugins from other terminal which has OS fedora in folder /var/lib/grafana/plugins/. And restarted grafana server
When I am adding world-map in panel it is showing only Legends, Zoom In Zoom Out buttons and copy right texts in panel. Not showing map. Even when I mouse over pannel mouse pointer turns into "Hand" but not displaying "World-Map"
Any Idea what causing this issue ?
If you do not have an Internet connection then Worldmap will not work.
Worldmap needs an internet connection to reach a tile map server so that it can show the map and to be able to zoom in. The plugin uses a free service from CartoDB which is based on the maps from OpenStreetMap.
If you really, really need the Worldmap plugin, are a programmer and have some free time then you could try implementing an offline mode for Worldmap.
A more in-depth discussion about adding an offline capability to Worldmap can be found in this GitHub issue.
