Hi All,
We are using SNMP (MRTG & 3rd Party Software - CA eHealth) & NetFlow (3rd Party Software - CA NetQoS) to monitor our router interface utilization and traffic. However the Trend report of SNMP and NetFlow are showing difference in utilization.
Anyone have any idea why this is happening? or Is it the expected scenerio?
Thanks in advance.

Adnan

Hi Jake,
Thank you very much for your informative reply. Please find my answers according to your suggested points.
1) Ok in our case.
2) Ok in our case.
3) Ok, I guess. The router we are monitoring is sitting on between Internet and Firewall. The NetQoS server is in inside zone and the router on outside zone. The interface we are monitoring of that router is connected to our another network. So the link is NetQoS Server>FW>Router.
4) OK, I guess. We are tring only with ingress. Egress is removed.
5) Ok, I guess. There is no encrypted tunnel associated with that router interface.
6) This thing we might need to check. Is there any way we can check this? In case, the cache is full, How can we increase the cache? We are using Cisco 7606 so I believe there should'nt be any issue to allowcate more memory to cache.
In addition to this I am sharing you the picture of Interface Unization difference of MRTG and CA NetQoS NetFlow so that you can have a clear view. Please see below,
