LDMGA is not a network monitoring device, and can not monitor link usage. I would suggest looking at mrtg, or other tools. You may want to enter this as an ER for future releases of the product. The only item I've seen to see what machines are using the gateway is brokercert table sessioncount table. I think the appliance is great but falls short in showing the true ROI of the device (example, RC connections via the appliance should be able to be reported on and weighted higher than normal RC connections or in your example Software Distribution via the gateway should be able to be reported on and weighted higher than normal SD).
