Understanding FreeRADIUS statistics

[dominic.stalder at unibe.ch]

Dear community

I read about the server statistics (https://freeradius.org/documentation/freeradius-server/3.2.4/howto/monitoring/statistics.html) but still don’t get it a 100%. I use this information as a reference:

Received Access-Accept Id 39 from 127.0.0.1:46c9 to 127.0.0.1:49906 length 596
     FreeRADIUS-Total-Access-Requests = 592
     FreeRADIUS-Total-Access-Accepts = 13
     FreeRADIUS-Total-Access-Rejects = 0
     FreeRADIUS-Total-Access-Challenges = 135
     FreeRADIUS-Total-Auth-Responses = 148
     FreeRADIUS-Total-Auth-Duplicate-Requests = 0
     FreeRADIUS-Total-Auth-Malformed-Requests = 0
     FreeRADIUS-Total-Auth-Invalid-Requests = 0
     FreeRADIUS-Total-Auth-Dropped-Requests = 0
     FreeRADIUS-Total-Auth-Unknown-Types = 0
     FreeRADIUS-Total-Auth-Conflicts = 0
     ...
     FreeRADIUS-Total-Proxy-Access-Requests = 39
     FreeRADIUS-Total-Proxy-Access-Accepts = 0
     FreeRADIUS-Total-Proxy-Access-Rejects = 0
     FreeRADIUS-Total-Proxy-Access-Challenges = 39
     FreeRADIUS-Total-Proxy-Auth-Responses = 39
     FreeRADIUS-Total-Proxy-Auth-Duplicate-Requests = 0
     FreeRADIUS-Total-Proxy-Auth-Malformed-Requests = 0
     FreeRADIUS-Total-Proxy-Auth-Invalid-Requests = 0
     FreeRADIUS-Total-Proxy-Auth-Dropped-Requests = 0
     FreeRADIUS-Total-Proxy-Auth-Unknown-Types = 0
     FreeRADIUS-Total-Proxy-Accounting-Requests = 0
     FreeRADIUS-Total-Proxy-Accounting-Responses = 0
     FreeRADIUS-Total-Proxy-Acct-Duplicate-Requests = 0
     FreeRADIUS-Total-Proxy-Acct-Malformed-Requests = 0
     FreeRADIUS-Total-Proxy-Acct-Invalid-Requests = 0
     FreeRADIUS-Total-Proxy-Acct-Dropped-Requests = 0
     FreeRADIUS-Total-Proxy-Acct-Unknown-Types = 0
     FreeRADIUS-Stats-Start-Time = "Jun 21 2024 11:08:37 CEST"

Some questions you could maybe answer me:

1. The total numbers are an incremented total since “FreeRADIUS-Stats-Start-Time”, is that correct?


2. Based on which additional value could I calculate the percentage of successful RADIUS “tries” (“FreeRADIUS-Total-Access-Accepts” and ???)?
a) There is a massive difference between “FreeRADIUS-Total-Access-Accepts” and “FreeRADIUS-Total-Access-Requests” or “FreeRADIUS-Total-Auth-Responses” and why is that?
b) somehow the values for “FreeRADIUS-Total-Access-Accepts” and “FreeRADIUS-Total-Access-Rejects” should somehow correlate with any of the other total values; or I am completely wrong about this?


3. Concerning the Proxy-statistics:
a) Why are the values for  FreeRADIUS-Total-Proxy-Access-Accepts and FreeRADIUS-Total-Proxy-Access-Rejects always = 0?

Thanks a lot for any help concerning the statistics; I am pretty new to FreeRADIUS and any help is appreciated.

Dominic
