As a user of OpsnShift I want to be able to tell if my underlying network is providing a solid foundation for my SDN.

I also want to be sure that my SDN is performing correctly.

We need to make sure there is an easy way to see the node-to-node performance numbers across the cluster.  We also need to see if we can alert on bad underlay performance (without too many false positives) and we need to see if we can push any meaningful metrics up to insights (can we do a median and a standard distribution across nodes?)
