Hi All,

I get a interesting finding that on the traffic volume shown by the netflow analyzer when comparing with our MRTG graph.

We have a router interface connecting a 2M E1 link. From our MRTG workstation, the max. interface bandwidth is aroung 1.8Mbits.


When we compare the data with our Netflow analyzer (v8.5), the one minute graph show the average bandwidth is over 30Mbytes...

2M link’s theoretical max. throughput (one minute) is 2M x 60 = 120Mbits (i.e. ~ 15Mbytes), but the figure in netflow analyzer (version 8.5 on Redhat Linux 5.5) shows ~30Mbytes, is that abnormal?

Thanks

Bong So
