[LARTC] Bandwidth monitoring tool

[LARTC] Bandwidth monitoring tool

[Omry Yadan]

Hi.

I am trying to shape my upstream bandwidth, mostly per port. and I am 
having some problems getting things to work the way I want them to.

before I throw my configuration at you guys ;), I`d like to debug it by 
myself - but I was not able to find a tool that allow me to

monitor current bandwidth usage per port (and preferably even per port+ip).

I want to know what is the current bandwidth passing through port 80 
(all connections), and in port 80, I`d like to

know what is the badnwidth usage per IP (regardless of the number of 
sockets that are opened from that IP).

anyone?


    thanks.

       Omry.

You can do this with iptraf. You can call it with

iptraf -s{yourinterface} -t1 -B

and it will output per port statistics in it's logfile for 1 minute (-t1) that
looks like this:


TCP/22: 564 packets, 101772 bytes total, 13.57 kbits/s; 341 packets, 24968
bytes incoming, 3.32 kbits/s; 223 packets, 76804 bytes outgoing, 10.23 kbits/s

TCP/80: 727 packets, 469337 bytes total, 62.57 kbits/s; 329 packets, 29763
bytes incoming, 3.97 kbits/s; 398 packets, 439574 bytes outgoing, 58.60
kbits/s

UDP/53: 176 packets, 22362 bytes total, 2.97 kbits/s; 88 packets, 11181 bytes
incoming, 1.48 kbits/s; 88 packets, 11181 bytes outgoing, 1.48 kbits/s

TCP/25: 20 packets, 5768 bytes total, 2.71 kbits/s; 11 packets, 4675 bytes
incoming, 2.18 kbits/s; 9 packets, 1093 bytes outgoing, 0.47 kbits/s

You can parse this and create some graphs for example with rrdtool.

Cheers,
Andreas

Here a short example (taken from a article in the linux magazin)

TRAFLOG=/var/log/iptraf/tcp_udp_services-eth1.log
WDIR=/usr/local/iptraf-stats
TODAY=$(/bin/date +%s)
UDATE=$(/bin/date +%Y%m%d)

echo -n "Extracting Data from Logfile $TRAFLOG... "
SMTP=$(grep "TCP/25"  $TRAFLOG|tail -n1| cut -f2 -d"," | cut -f2 -d" ")
HTTP=$(grep "TCP/80" $TRAFLOG|tail -n1| cut -f2 -d"," | cut -f2 -d" ")
POP3=$(grep "TCP/110" $TRAFLOG|tail -n1| cut -f2 -d"," | cut -f2 -d" ")
IMAP=$(grep "TCP/143" $TRAFLOG|tail -n1| cut -f2 -d"," | cut -f2 -d" ")

echo "Values smtp: $SMTP"
echo "Values pop3: $POP3"
echo "Values imap: $IMAP"
echo "Values http: $HTTP"

# archieve results

echo -n "Archieving results...$WDIR/data/*... "
echo $SMTP >> $WDIR/data/smtp-history.$UDATE
echo $POP3 >> $WDIR/data/pop3-history.$UDATE
echo $IMAP >> $WDIR/data/imap-history.$UDATE
echo $HTTP >> $WDIR/data/http-history.$UDATE

echo -n "Updating RRD-Graphics and generate GIF... "
rrdtool update $WDIR/rrd/mailserver.rrd $TODAY:$SMTP:$POP3:$IMAP

Hi.

You can also parse "tc class show dev eth0" and display
the result using mrtg.
