One possible way to gather statistics per-jail-ip is to use 'ipfw count'
rules for each jail ip on the base system. Then you can write some
scripts and pass accumulated data to MRTG. MRTG can grab data not only from
SNMP, but from external programms via stdin. Such external program
have to send to it's stdout four strings. This is described in MRTG
documentation.
The simplest scripts in this case should pass to MRTG current
values of ipfw count values for inbound and outbound traffic.
You need as many such scripts as you have jails on the host. MRTG
(and Apache) should be installed on the same machine with jails.
But it is possible to write tcp- or udp-aware daemon and client
and run MRTG on another host.
And if you want you can use RRDTool - it can show more precious
pictures than MRTG. MRTG shows more averaged values.
