The linux scripts here:
https://github.com/bot779?tab=reposit...
do various things.
ruckus-zdroamers: shows client activity either for the day, or "currently".
(assumes it's running on a linux syslog server that's receiving controller logs)
bandperclient: shows how much traffic each client is using.
You may need some linux experience to make use of these scripts.
Let me know if/what trouble you have using them.
