Recently I have a poc of OPM&NFA for new client.  Customer has about 1500 devices, including routers/switches,  and then they want to monitor about 20 interfaces to know network application and detail traffic.

    As above mention, we recommend that customer can use OPM central-probe mode and NFA standalone integrates with probe mode. We think the solution can satisfy customer's requirement.

    We downloaded the newest OPM and NFA to install and deploy. After that, we found that OPM probe can integrate with NFA successfully in GUI of probe, and the NFA can run normally. 

    However, we can't see the any detail data of application of interface snapshot, it is blank widget. I have restarted the NFA server and OPM probe server, it still gave us blank widget. How to troubleshoot this issue, please give advice, thx in advance!
