I'm using the Maps+ for Splunk app and have the visualisations working fine.
I am trying now to use a custom overlay kml/kmz file created from within Google Earth app.
From the maps+ instructions on how to do this:
Add custom overlays to the map. The first release implements a KML or KMZ overlay feature. If you have existing KML/KMZ files that define features (polyline, polygons, whatever) you can now leverage them to overlay these features on the map.
Copy any KML or KMZ files into the following directory
Click Format and selct the Overlays tab. Enter a comma separated list of filenames that you uploaded to the above directory. File order dictates feature layering - e.g., file1.kml renders beneath file2.kml
The files will be asynchronously loaded when the map is rendered.
Did this and can't see the overlay in the map at all after browser refresh
Anyone who has done this successfully or has some clue where to start troubleshooting your help would be greatly appreciated
For completeness I also tried this location for the files
