Hi Aaron, Do you have sampling configured on your netflow exporters? Netflow apps will only have data for flows that they see, and sampling will reduce that value significantly. For example, my aggregate inbound traffic is just shy of 20 Gbps, but as I only sample 1-out-of-6000 random packets, my nfsen bps graph peaks at around 3 Mbps.
SNMP-based apps a la MRTG behave differently; since they're just graphing interface counters/OIDs (instead of extrapolating based on netflow samples), they have a better glimpse into raw bits flowing across your links. Does this help?
