What I am particular interested in is, where and how the JSON object are created and how they look like. (The first step would be in which package/file is the JSON file created? Couln't find yet) What I am also interested in is how the management server chooses the host. As I assume from the log files it sends keep-alives to the management server? It would be really great if you could give me a hand with these questions Best regards Watnuss --========GMXBoundary168961344858314193414--
