[ovirt-users] VM Network activity on ovirt UI

I'm generating network activity on a VM using iperf.The VM acts as an iperf client.On the client,iperf reports that data has been successfully sent to iperf server.The iperf server also shows that it's successfully receiving data from the iperf client.But,network is at 0% on the ovirt UI.The client and server are on different private networks. On the same VM,when I generate network activity by fetching a file from a public network using wget,the network column correctly shows activity on the ovirt UI for the VM. Could someone help me understand why I am unable to see network activity on the ovirt UI when iperf is used? Appreciate your help.TIA.
