Node graph for multi-host ROS network

edit

Assuming a situation where nodes are distributed on multiple hosts, is there a way to oversee at a single view which nodes are running on which hosts?

I imagine something like rqt_graph, with which has an option to show either ROS_IP or ROS_HOSTNAME values on each node. I found this page in rocon tutorial but doesn't seem to provide what I'm looking for.

It can be a useful debug tool multiple hosts ROS network.

Here whether it's a single or multi ROS master network does not matter to me.
