Hi guys,

I need a little help in counting the traffic via my
router/firewall/keepalived machine (yes it's one box with 3 nics)

I have pmacct setup with this config and it is working a treat for my
"normal" servers, I'm just not sure now how do I count the traffic for the
load balanced servers. I do know I have to run multiple pmacctd daemons with
multiple configs to track multiple interfaces, but I'm not sure which
interface I need to track.

debug: true
logfile: /var/log/pmacct.log
daemonize: true
promisc: false
interface: eth1

plugins: mysql[in0], mysql[out0]

aggregate[in0]: dst_port,dst_host,proto
aggregate_filter[in0]: dst net 202.45.102.0/24
sql_table[in0]: eth1_in

aggregate[out0]: src_port,src_host,proto
aggregate_filter[out0]: src net 202.45.102.0/24
sql_table[out0]: eth1_out

sql_recovery_logfile[in0]: /root/recovery-in0.sql
sql_recovery_logfile[out0]: /root/recovery-out0.sql

sql_host: XXXXXX
sql_db: pmacct
sql_table_version: 1
sql_user: XXXXXX
sql_passwd: XXXXXX
sql_refresh_time: 60
sql_optimize_clauses: true
sql_history: 1m
sql_history_roundoff: mh
sql_dont_try_update: true

The issue is I now have setup keepalived to load balance a couple of servers
via a 3rd network card.
Being a firewall as well as my router AND load balancer the keepalived side
of things puts the virtual ip's onto eth0, and then nats these via eth2 for
the machines I'm load balancing.

firewall# ip addr
3: eth0: <BROADCAST,MULTICAST,UP> mtu 1500 qdisc pfifo_fast qlen 1000
    link/ether 00:40:d0:43:b7:cc brd ff:ff:ff:ff:ff:ff
    inet 202.45.103.86/30 brd 202.45.103.87 scope global eth0
    inet 202.45.102.91/32 scope global eth0
    inet 202.45.102.92/32 scope global eth0
    inet 202.45.102.71/32 scope global eth0
    inet 202.45.102.72/32 scope global eth0
4: eth1: <BROADCAST,MULTICAST,UP> mtu 1500 qdisc pfifo_fast qlen 1000
    link/ether 00:0e:0c:d0:71:bc brd ff:ff:ff:ff:ff:ff
    inet 202.45.102.1/25 brd 202.45.102.127 scope global eth1
    inet 202.45.102.90/32 scope global eth1
    inet 202.45.102.70/32 scope global eth1
5: eth2: <BROADCAST,MULTICAST,UP> mtu 1500 qdisc pfifo_fast qlen 1000
    link/ether 00:40:d0:43:b7:cd brd ff:ff:ff:ff:ff:ff
    inet 192.168.1.1/24 brd 192.168.1.255 scope global eth2

I have no issues tracking the traffic for all the "normal" servers via eth1
but how do I account for the keepalived virtual ip's on eth0 (and for some
reason the virtual ip's on eth1 202.45.102.90 and 202.45.102.70 aren't
showing any traffic with the above config)
I guess I'm not sure how to setup the aggregate filters for accounting the
traffic on eth0 and eth2.

Cheers
Ad
