Nload is a console application which can be used to monitor network traffic and bandwidth usage in real time and it also visualizes the traffic by providing two easy to understand graphs. If you like to learn more about nethogs and explore it in a very deep way than don't hesitate to read our full tutorial on this network bandwidth monitoring tool. To me nethogs is very easy to use, maybe because I like it so much that I use it all the time to monitor network bandwidth on my Ubuntu 12.04 LTS machine.įor example to sniff in promiscious the option -p is used like shown in the following command.

It is feature rich, supports both IPv4 and IPv6 and in my opinion is the best utility when you want to identify programs that are consuming all your bandwidth on your linux machine.Ī linux user can use nethogs to show TCP download and upload-speed per process, monitor a specific device by using the command nethogs eth0 where eth0 is the name of the device you want to get information from and also get information on the speed at which the data is currently being transferred. Nethogs is a free tool that is very handy when it comes to find out which PID is causing the trouble with your network traffic as it groups bandwidth by process instead of breaking the traffic down per protocol or per subnet, like most tools do. For example nethogs can be used to show bandwidth per process in case you want to know the application which is consuming your entire network resources, iftop can be used to show bandwidth per socket connection and tools like nload help to get information about the overall bandwidth. There are a lot of tools available like nethogs, ntopng, nload, iftop, iptraf, bmon, slurm, tcptrack, cbm, netwatch, collectl, trafshow, cacti, etherape, ipband, jnettop, netspeed and speedometer.Įach one of the above tools has its own specifics but at the end all they do is monitor network traffic and there is not really only one way to do the job. In this tutorial lets discuss best networking monitoring tools available for linux system.
