Reporting on subinterface utilization

I am trying to come up with a way to create a graph that shows the utilization of an overall LAG and its subinterfaces. Orion is able to poll all of the subinterfaces just fine, but there doesnt seem to be any grouping of those subinterfaces to a LAG. The only real way I can tell it is a subinterface is that its type is Layer 2 virtual LAN while the LAG is a Link aggregator.

The piece of equipment is a Fortinet firewall and I believe the model is a fgt3240c. Any ideas would be appreciated. It seems Ive hit, for lack of a better term, writers block.

at least on cisco stuff, you model the portchannel/lag and you model the interfaces. that way you can see how it's being used and total utilization to individual port utilization

Both are being monitored, but on a single device we have multiple LAGs and I do not know which interface goes to which LAG without asking our networking people.

Once that is tackled, how would you go about adding all of the subinterfaces and the associated LAG to a graph to show utilization of everything at the same time?
