Stealthwatch SMC shows no data on traffic and flow

Hello, everyone,

are there anyone share the similar symptoms that the SMC can't correctly display traffic and flow data like the screenshots below:

  • SMC version: 7.0
  • FlowCollector version: 7.0

Below is the web console of the FlowCollector I used in the lab (30.100.101.21), it does show it have been collecting flows.

The lab has been running for few weeks and I still can't see the traffic and flow graphs. Please help.

Thanks.

Re: Stealthwatch SMC shows no data on traffic and flow

Yes, thanks for replying. I should have mentioned my lab setup.

The SMC is centrally managing a FlowCollector and a FlowSensor within a private network. All of them are hosting in a server using VMware. The 4500-X is sending NetFlow to the FlowCollector and I am also using SPAN in a 2960-X to send NetFlow to the FlowSensor. 

 

But I got them working now. I just tried aligning all VMware virtual adapters of VMs to use VMXNET3, and reboot. Boo, the graphs are suddenly showing something now.

Is the flow collector registered to your SMC?
