One way is to parse through radius logs (each controller has its unique client name) and generate stats for auth/sec, auth/min, auth/day. You can also generate graphs from scripts. I wrote a few to generate and mail graphic reports daily.

My first instinct is to port mirror the controller to a large enough box to handle the traffic and have a filter looking for port 1645/1812 (whatever your RADIUS AUTH port is) so you only capture that traffic (I would use tcpdump). Then you might be able to do some stats on it if you capture for an hour or so. -- Jeremy L.

I was curious if anyone has embarked on a similar journey and tried to measure auth rates coming from their controllers? I have a couple of ideas that I’m up for sharing, but I wanted to see if anyone else has done this.
