> - You can ask for ALL auth statistics (across all "listen" sockets)
> - Or, specify a socket IP/port, and it will return the stats for that
> - You can do this for auth/acct sockets independently
> - you can query statistics for one client, and optionally specify
> the server IP/port (if the "listen" section has it's own clients)
> - you can ask for total auth/acct packets that are proxied to home servers
> - you can ask for total auth/acct packets that are sent to individual
> home servers.
> - you can tell when a home server was marked dead / alive, and how many
> requests have been sent, but not responded to.
> - you can ask for stats on the internal queues in the server (e.g. if
> it's busy, there will be many packets waiting, and all of the child
> threads will be doing work)
> The end result is that it's simpler to implement than SNMP, has fewer
> issues, and returns more data than the SNMP statistics would return.
