Iftop shows a real time updated list of network usage bandwidth every 2, 10 and 40 seconds on average. It will show a quick overview of network activities on an interface. ![]() In this article we have came up with another excellent program called Interface TOP (IFTOP) is a real time console-based network bandwidth monitoring tool. Handy for answering the question "why is our ADSL link so slow?".In our earlier article, we have reviewed the usage of TOP Command and it’s parameters. It listens to network traffic on a named interface and displays a table of current bandwidth usage by pairs of hosts. Iftop does for network usage what top(1) does for CPU usage. Solution 3Īlso iftop: display bandwidth usage on an interface NetHogs can be built on Mac OS X and FreeBSD, but it will only show connections, not processes. ![]() Since NetHogs heavily relies on /proc, most features are only available on Linux. This makes it easy to identify programs that have gone wild and are suddenly taking up your bandwidth. If there's suddenly a lot of network traffic, you can fire up NetHogs and immediately see which PID is causing this. NetHogs does not rely on a special kernel module to be loaded. Instead of breaking the traffic down per protocol or per subnet, like most tools do, it groups bandwidth by process. NetHogs is probably what you're looking for:Ī small 'net top' tool. Edit: it only shows the streams, not the owner processes. ![]()
