Traffic Rates Inaccurate

Traffic Rates Inaccurate

I just set up Netflow Analyzer to capture data from our Juniper SRX firewall. I used the recommended settings for Jflow (with some modifications due to code differences) from the documentation but it appears to be off by a factor of 10. For example, Netflow is reporting traffic rates between 50-100Mbps: https://i.imgur.com/qTQU5CS.png. However, this interface is only connected to a 10Mbps internet circuit. Here are the traffic graphs from the device itself: https://i.imgur.com/UQASw7j.png.

Here's the relevant config from the Juniper:

  1. sampling {
  2.     input {
  3.         rate 100;
  4.         run-length 9;
  5.         max-packets-per-second 7000;
  6.     }
  7.     family inet {
  8.         output {
  9.             flow-server 172.16.0.68 {
  10.                 port 9996;
  11.                 no-local-dump;
  12.                 source-address 172.16.1.16;
  13.                 version 5;
  14.             }
  15.         }
  16.     }
  17. }


And here's the interface in Netflow Analyzer: http://i.imgur.com/hAkIW4c.png


What am I missing here? Thanks!
