I have 3 points to make in this posting.
As probably most customers can attest marking or re-marking your traffic on egress from your WAN Routers is the de facto standard....if you are an enterprise customer.
Point 1
Your tool has QOS setup as everything being a default Ingress setting. What this effectively means is the the CBQOS drill downs results in no data to be seen and the requirement to change the selection to BOTH or Egress each and every time for every chart element or drill down. It has no memory of your last selection nor are there any selectable elements.
Point 2
On this same topic, the default Component viewable on the main NTA page has these settings:
You will notice that for Traffic In and Traffic Out there is no data. Yet when you drill through on an individual component..you will indeed see the traffic.

I suspect this is some sort of by design decision.
Point 3
Lastly the only way I was able to include anything at all about CBQOS on any page at all was by using an IFRAME..there is no selectable stuff nor Reports written etc. For me the very fact the CBQOS lives in Netflow is weird. It's a standard MIB that is SNMP pollable and should be available as part of the Universal device poller. Or IPSLA/VOIP module or something other than NTA.
