We have a provider claiming that they are getting ingress policer hits at 2Gb on their ingress from us. Both their and our BW monitoring does not show us going outbound above 800 Mbps. So they are adamant that in between our 30 second poll interval we are getting 1.2 Gbps spikes triggering their policers. They really aren't adept at understanding how ridiculous this is from our viewpoint as our services are broken up into 32 Mbps max individual flows. Typical is 8Mbps. Basically we would need dozens of people standing by and triggering dozens of errant flows with several Mbps each in order to over utilize this circuit at 1.2 Gbps more... making sure they detuned these errant flows within that 30 seconds as well. It's highly unlikely. So my goal is to capture per second BW utilization to debunk their explanation. What is the best method? I'm aware of packet capture options (cisco asr 1000). Not sure how viable that is. Any other solutions?
Edit: Router is at a data center.
