Class of Service/Quality of Service Graphs

So I found that Juniper has a COS MIB and I’m curious about putting that into a graph.

I think it might be best to add COS graphs to the interface graphs (for devices that have a MIB), or but maybe other’s feel it’s best to have a COS section under the “graphs” portion. (?)

Is this doable, or would I be better off trying to add the devices/interfaces I care about as some sort of custom graph?
