Freebsd comes with bsnmp or if you prefer ports try net-snmp from ports,
these will let you query the snmp OID's mentioned.
I use a little perl script to query them and graph them myself for my
home router.
If you dont like snmp for some reason, putting something together using
netstat shouldnt be too hard. For example
(12:45:12 ~) 0 # netstat -b -f inet -I fxp1
NameMtu Network Address Ipkts Ierrs Ibytes
Opkts Oerrs Obytes Coll
fxp1 1500 10.0.0.0/25 intgate 806889 - 118190683
1247743 - 1621177480 -
(excuse word wrap but it shouldnt be too hard to work out)
running this every minute from cron would make it easy to grab the in
(Ibytes) or out (Obytes) traffc and perform actions accordingly.
very quick and dirty example:
-cut
#!/bin/sh
IFNAME=fxp0
OLDIN=$(netstat -b -I $IFNAME | awk '/Link/{print $7}')
OLDOUT=$(netstat -b -I $IFNAME | awk '/Link/{print $10}')
sleep 10
NEWIN=$(netstat -b -I $IFNAME | awk '/Link/{print $7}')
NEWOUT=$(netstat -b -I $IFNAME | awk '/Link/{print $10}')
INBPS=$(echo ( $NEWIN - $OLDIN ) / 10 | bc )
OUTBPS=$(echo ( $NEWOUT - $OLDOUT ) / 10 | bc )
echo $IFNAME is doing $INBPS bytes a second inbound
echo $IFNAME is doing $OUTBPS bytes a second outbound
--cut
sample output:
(13:50:09 ~) 0 # sh foo.sh
fxp0 is doing 1247 bytes a second inbound
fxp0 is doing 51175 bytes a second outbound

Hello everybody...
Need to view and get real-time reporting of outgoing=hannel to
Internet?
I think, that this is may be realized by means of ip=w (e.g. - get
counters
of count rules for Internet and divide them to time,=hich passed
between
analyzing)
But, maybe, there is an utility, to which I can comm=nicate (or
which could
analyze) my outgoing channel to Internet - and repor= me (mean some
redirection script) when an outgoing channel gets ov=rflowed, and I
need to
redirect all other outgoing traffic to another chann=l.
I would like to clear: I have to channels for Intern=t, meaned for
gaming
club - but I don't have enough finance to afford buy=ng some Cisco
device
and this 2 channel are 512 kilobits and 768 kilobits=f outgoing
traffic
Please, help

Re: Re[2]: Analyze load of the channel to Internet
If you simply want ingress/egress load, nTop provides much more detail than I think you need, but in your case you would run it directly on your BSD routers. It will load libpcap and capture/analyze/graph the traffic flowing through your routers.
