That’s what I’ve just done this morning. I had to set up a “NodeWatcher” GenServer that is started when the application starts. When a new game is started I check to see if there are any new nodes connected and if so add them to the NodeWatcher. The NodeWatcher runs Node.monitor/2 every time a node is added to its state. When the NodeWatcher receives a {:nodedown, node} message I have a handle_info call that removes the node from the watcher’s state and outputs confirmation that it has been removed to the terminal. Ultimately I think I’d like to have the ability to keep games associated with nodes, and if a given node goes down it starts a timer for the game to shutdown if the node does not reconnect in x amount of time.
