Data usage /network traffic monitoring

nik · September 18, 2018, 3:50am

Looking for a way to see how much internet data each application is using. Currently my Librem 15 running pureos is hemorrhaging data.

System manager and sort by network, if you want more detail use nethogs, just type

nethogs

Into there terminal

thanks for your reply. I could find System monitor (but not manager) and under the resources tab > network history, I am able to see total MB in and out.
Typing nethogs into terminal produced this error -
Could not find the database of available applications, run update-command-not-found as root to fix this

Running update-command-not-found produced the same error.

Advice on how to fix this would be appreciated.
Regards

Nethogs
=======

[![Build Status](https://travis-ci.org/raboof/nethogs.svg?branch=master)](https://travis-ci.org/raboof/nethogs)

Introduction
------------

NetHogs is a small 'net top' tool. Instead of breaking the traffic down per protocol or per subnet, like most tools do, **it groups bandwidth by process**. 

NetHogs does not rely on a special kernel module to be loaded. If there's suddenly a lot of network traffic, you can fire up NetHogs and immediately see which PID is causing this. This makes it easy to identify programs that have gone wild and are suddenly taking up your bandwidth.

Since NetHogs heavily relies on `/proc`, most features are only available on Linux.
NetHogs can be built on Mac OS X and FreeBSD, but it will only show connections, not processes.

Status
------

Nethogs is a mature piece of software included in most Linux distributions.

There’s the git for it though it should be a preinstalled debian package
