Debian Bandwidth Monitoring

nikc

Hi All.

Anyone have any recomendations for a tool I can use to monitor bandwidth usage of a Debian VPS.

Ideally I'd like to get a graphical representation of speeds and volumes.

Cheers

Loving Vnstat .... but is there tools to monitor traffic on a virtual interface ? (eth0:0)

BlazeMuis

with bwm-ng you can see the current bandwidth being used
and you could use munin for the graphical stats

nikc you can just add the venet

Munin and vnstat is a good combo. Use it on my vps. Maybe http://hostedmunin.com if you don't want to setup a munin server.

I'm using vnstat + phpsvnstat.
Install vnstat and configure to monitor the interface ,

vnstat --iflist
vnstat -u -i eth0

Just edit the config.php to monitor the eth0 / venet0 / tun0.

Yup, love vnstat, but everything I read says it cant monitor a virtual interface ....

vnstat --iflist
Available interfaces: lo tunl0 sit0 dummy0 eth0 tun0 ip6tnl0

No eth0:0

nikc

Same for munin it seems, only sees the physical adapter not the virtual.

@nikc - As far as I know it will be picked by physical adapter counter, in your case eth0

Nikc: identify high bandwidth connections with iptstate: http://www.phildev.net/iptstate/screenshot.shtml

sudo apt-get install iptstate

You can kill connections too by highlighting them and pressing x.

man iptstate

iftop to get a detailed view of realtime usage, and vnstat for tracking over periods of time.
