Solarwind NTA 4.1 does not support SSID usage.
I have requested this feature about a year ago, when I opened a ticket with a NTA support team, we use Cisco WLAN controllers and we cannot generate report on SSID utilization.
Last but not least, NTA traffic utilization reporting is away offset with NPM traffic utilization reporting.
This is for same interface, NPM is accurate for bandwidth utilization but NTA is completely out of order for bandwidth utilization. It is no use at all.
