Grafana for processing monitoring

@tsprinter sorry, but I have higher priority work at the moment than the Worldmap panel. We are all working hard on the next major release of Grafana and Worldmap works well enough for the worldPing app (which is the main usecase for us).

If you want help with this issue then you will have to give me more information. I could not reproduce it. If you are using the latest version of Grafana there is a query inspector to see the results of the queries. Otherwise, you will have to investigate using the Chrome Dev Tools.
