Pick the command that works with your system’s package manager. It is used to observe real-time network bandwidth and displays. Once your terminal is open, you can go ahead and install Nethogs. Nethogs is an open-source network monitoring tool with features similar to Linux top command. Just press CTRL + ALT + T and your default terminal emulator should open right up. If that’s something you’re interested in doing, a search engine will help you get there. NetHogs is a small ‘net top’ tool that allows monitoring network usage of a process running in the Linux system.Most common network monitoring tools break the traffic down per protocol or subnet, in contrast, nethogs groups bandwidth usage by process. It’s possible to use Nethogs without sudo, but we won’t be covering that here. We’ll be using ‘sudo’ for all of these commands. OpManagers powerful Linux network monitor lets you track network traffic, availability and performance of Linux devices in real-time. (There’s a future article about top and htop, when I get to it.) But, Nethogs is like a system monitor, except it’s a network monitor with some visual similarity with top. I suppose that’s mostly useful to those who know what ‘ top‘ is. OpManager offers a plethora of features to help you get to the root of a network issue. Advanced network troubleshooting: Get to the root of the issue. Nethogs – Net top tool grouping bandwidth per process Linux network monitor, windows network monitor, OpManager does the job and provides all the information in a common dashboard to simplify your time. Feel free to leave a comment telling us how you intend to use Nethogs.Īs stated, we’ll be using Nethogs. There are all sorts of reasons to monitor your network usage at this level. You can also filter based on either source or destination. or: rootserver tcpdump -i eth0 net 10.1.0.0/24. You might also be looking for rogue applications/malware that’s using up some of your bandwidth. You can also capture traffic to and from a specific network using the command below: rootserver tcpdump -i eth0 net 10.1.0.0 mask 255.255.255.0. UPDATE We’ve released the counterpart to this post: Monitoring and Tuning the Linux Networking Stack: Sending Data. Not everyone has unlimited bandwidth after all. This blog post explains how computers running the Linux kernel receive packets, as well as how to monitor and tune each component of the networking stack as packets flow from the network toward userland programs. Why would you want to monitor this? Well, you may want to know which applications are eating up most of your bandwidth. It’s actually easier than one might think and we’ll even show you how to install Nethogs on a variety of distros. Today’s article is going to tell you how to use Nethogs to monitor network usage on a per-application basis.
