I was wondering if there are any good applications to monitor how much data I use on my laptop in a month. My net connection has a restriction of how much data I can use after which the speed goes down considerably. I saw ntop, but I just wanted to ask if there are any other good options or suggestions regarding this. Regards.

Have you checked vnstat – Achu Feb 12 '12 at 17:30
You can use Data Monitor App for Linux – BigSack Aug 9 '12 at 9:36

I was in a similar situation, but with slow speeds after a certain amount of data usage is reached (now I have a 16 GB 12 Mbit plan ☺) and I used vnstat (package vnstat). It's a command-line app that displays the bandwidth usage for today and previous days. as soon as it is installed, it will start monitoring the usage.

Usage: run vnstat to view the statistics, vnstat -d for viewing daily usage. Add -i wlan0 to the previous command if you are using a wireless network. See the manual page for it by running man vnstat for more information.

I used the same in the past, you can get a gui for it now apparently - never used that though - – 23 93 26 35 19 57 3 89 Oct 5 '13 at 14:03
Thank you .How can I configure that ? – Raja Oct 5 '13 at 14:23
@rajagenupula well, there is nothing to configure! as soon as it is installed, it will start monitoring the usage. Run vnstat to view the statistics, vnstat -d -i <interface> for viewing daily usage. See the manual page by running man vnstat for more information. – Ramchandra Apte Oct 5 '13 at 15:07

You can check NTM - Network Traffic Monitor

This is very easy to setup – Raja Oct 5 '13 at 14:29

There is Datafox, an addon for Firefox.

This should monitor at least your bandwidth usage on the web, I don't know if it can monitor usage with other applications however.

Datafox has rather limited scope. From the add-on page: "Check your BSNL DataOne and MTNL Triband bandwidth utilization in Firefox at the click of a button." It doesn't seem to work for other ISPs. As you point out, monitoring bandwidth usage by other apps is also required. – user25656 Feb 13 '12 at 14:56

I have used NTM that was pretty easy to setup and nice. – Raja Oct 5 '13 at 14:20
ok enjoy and get away from extra bill – krishna kaanthh Oct 5 '13 at 14:23

I needed protocol granularity to see what was using data on my network, so I opted for ntop. It has a web interface, and worked out the box for me.
