-    % start the aten application if not part of a release
-    {ok, _Apps} = aten:start(),
-    % register interest in status changes for a node
-    ok = aten:register(node1@host),
-    % receive status change events
-    receive
-        {node_event, node1@host, down} -> ok;
-        {node_event, node1@host, up} -> ok
-    end
