I am trying to be proactive regarding scaling of RADIUS servers as we move to a new load-balanced environment. The idea is to know when we are getting close to a threshold and need to add another VM, allocate more CPU, RAM, etc.
I've used a traffic generator to simulate authentications against our FreeRADIUS VM's and so I know the max. number of auths/sec. that a server can handle and I've seen that the server will start to reject clients when it can't handle the load. So I am thinking a dashboard that graphs the auths per second, and pie chart that shows successful vs. failed requests with some alerting would allow us to preempt load/growth issues. It seems this info wouldn't be too difficult to grab from syslog and graph on a web page somehow. I am just wondering if any of you have already done this or something like this that you could share before I re-invent the wheel. Let me know.
