Network Bandwidth/Traffic Monitor

swiri

Anyone have a favourite network traffic monitor for linux?

I am looking for something that can monitor in real time and something that can monitor over time and generate usage graphs etc...

At the minute I am using iftop which seems pretty good for real time info. Im new to this so not sure how accurate it is?

Thanks

Khannie

If I want a snapshot I'll either use conky or the gnome system monitor.

Thanks Khannie. I never really looked at the System monitor in GNOME for that info before, thanks.

Unfortunately I am using Voyage Linux with no X windows so I need command line tools preferably.

iftop seems to be the best for real time network resource usage.

Now I just need something that will monitor over time and create a usage graph!

I bet you could script that handy enough. ifconfig has input / output info (almost certainly just plucked from something in /proc) (edit: or you could scrape it from iftop, though I haven't used that). You could store the information periodically and then graph it with gnuplot.

I did search for the same feature a few months ago while trying to stay under my bandwidth allowance per month and it seems that no mainstream solution exists.
I wrote a script based on netstat to record my upload/download usage on a txt file and another script to graphically display it.

I eventually switched to unlimited bandwidth :rolleyes:

It's the obvious solution.

I tried to save 5€ a month by limiting my bandwidth consumption. Which turned out to be just impossible :rolleyes:

It's an extra 12 for me to bump to unlimited. I can't justify it. That's 6 cans of my favourite beverage. At my very low tolerance for alcohol that's 2 good nights.

Try vnstat.
