The packet flow through a Federated Choria Network can be traced using mco federation trace dev1.example.net. It will publish a specially crafted message to the entire Federation that instructs it to trace the full path the packet takes through your network. It will then show the result in a hopefully meaningful way.
The network diagram above shows a Federated Collective and how a packet might flow across the network. When doing a trace you will see output like this:
