    Netflow Analyzer v. 10.8.0.5 - Juniper J-Flow Support?

    swf5002@psu.edu

      I thought I had read that J-flow is supported by this tool, but after configuring the ports that interested me for v9 J-Flow  and then connecting the tool, all I see is the traffic in / out, not Flow Type, and when I try starting the flow capture I get that Netflow is not detected on the selected interface.  I am trying to analyze traffic on a branch-site's SRX220.  Any ideas why it's not seeing this?  The firewall on both sides allows traffic on all ports to pass freely.

       

      Here are some relevant dumps from my config:

       

      Setting up Flow Monitoring -

      services {

          flow-monitoring {

              version9 {

                  template ipv4-test {

                      ipv4-template;

                  }

              }

         }

       

      forwarding-options {

          sampling {

              input {

                  rate 100;

                  run-length 3;

              }

              family inet {

                  output {

                      flow-server COLLECTOR_IPADDRESS {

                          port 2055;

                          version9 {

                              template {

                                  ipv4-test;

                              }

                          }

                      }

                      inline-jflow {

                          source-address DEVICE_WAN_IP;

                      }

                  }

              }

          }

       

      vlan {

          /* Infrastructure Devices */

          unit 2800 {

              family inet {

                  sampling {

                      input;

                  }

                  address DEVICE_INTERNAL_IP (GW for this subnet/vlan pair);

              }

          }
