Unfortunately there is no reporting capabilities directly in the controllers or switches. Do you have another network management platform? (Solarwinds, PRTG, etc)
You can get some information via SNMP (# users connected, user-table entries, etc), but you'd have to build the graphs in the NMS.
You could also write a script that greps commands like "show user-table", "show ap essid", etc and dumps it out to a text file. Not the prettiest, but at least you will have some data.
AirWave has spoiled us :smileyhappy:
