Aside from mass of traffic and ASNs, a good measure of success (for me) is creation of PNIs. That requires traffic + ASN + good xcon costs (like 0). Just so the guys that need to make the graphs know what they are being asked for; are you asking for peer ASNs or origin ASNs reachable from the exchange? Or, maybe both now that I think of it.
