WLC & Netflow: No interfaces under NTA?

Hello all. We're running 2023.1.0 and I've recently pointed all my Netflow from a 5520 to NTA. I can confirm the flows are getting to NTA however the WLC interfaces discovered under NPM are not showing up in NTA. I'm also not seeing any data at the WLC Node level - AVC is enabled on each WLAN and the monitor was applied. I'm hoping someone might hep me understand what I could be missing here. I would greatly appreciate it.

NTA:

NPM:

No data:

  • Thank you Don. My issue isn't with the bandwidth utilization really. It's the fact that under NTA, the WLC is being shown as receiving Netflow traffic but the graphs don't show any data. Additionally, the WLC's interfaces are discovered under NPM (so i believe SNMP is working) BUT they aren't showing up under NTA. See the first screenshot where the Interfaces column says 0.
