Most of the time while travelling I have to carry data card. In some cases data access plan is limited on these data card.

To avoid crossing the data limit, I have to login to service provider / carrier website to check the current data usage.

But now I don’t have to worry about data plans and excess usage due to NETWORK TRAFFIC MONITOR (NTM)

Basically NTM is an application to monitor data usage on particular interface. It can display a complete report for received and transmitted packets. Once the basic configuration is done, it will automatically disconnect you from the network after a certain period of time or after the traffic exceeds the value you set (MB).

By default, NTM will use the “ppp0” network interface which is your data card interface but if you want it to track your wireless traffic, use “wlan0” instead.

Following are the characteristics:

  • Choice of the interface to monitoring.
  • Period to monitoring: Day, Week, Month, Year or Custom Days. With autoupdate.
  • Threshold: Auto disconnection if a limit is reached (by NetworkManager).
  • Traffic Monitoring: Inbound, outbound and total traffic; Show the traffic speed.
  • Time Monitoring: Total time of connections in the period.
  • Time Slot Monitoring: Number of sessions used.
  • Reports: Show of average values and daily traffic of a configurable period.
  • Online checking with NetworkManager or by “Ping Mode”.
  • The traffic is attributed to the day when the session began.
  • Not need root privilege.
  • Not invasive, use a system try icon.
  • Tested with: Ubuntu 9.10 (Karmic Koala), Kubuntu 9.10, Xubuntu 9.10, Ubuntu 9.10 Netbook Remix, Ubuntu 9.04 (Jaunty Jackalope), Fedora 11, Fedora 12,

You can download the debian package from

Download the package to tmp directory and install it via dpkg command

cd /tmp
sudo dpkg -i ntm-1.3.deb

That’s it. Now you can run NTM from Application > Internet > NTM
