Once you have identified the process which is consuming the bandwidth, note down the its PID (or, Process ID) and take necessary actions on it. Apart from that, we can also press s to sort the sent traffic and r to sort receive traffic. And, with every keypress ( m) event it would switch modes for us. Where, value of n can be any of the following –įor instance, to get the view mode in Total KB use – sudo nethogs -v 1Īlternately, if you don’t want to change view modes this way then, press m after you launch NetHogs. We can change that as shown below – sudo nethogs -v n By default it shows – view mode as 0 (0 KB/s). And, rest columns would be shown depending on the configuration you chose in the beginning.
Just below that, we see four columns at least – PID, USER, PROGRAM and DEV. The first thing you notice at top left is the version number installed. Hence, open a terminal and issue the following – sudo apt updateĪnd, to install NetHogs – sudo apt install nethogs Monitor Bandwidth usage by Process with NetHogsįollowing command would run the utility in terminal – sudo nethogs So, all we need to do is – update the repository and install the package through following commands. NetHogs package is a part of standard Ubuntu repository. In case you don’t have one then, we advise you to contact your System Administrator for assistance.
Note: Following operations require superuser privileges. We cover NetHogs package installation steps next. For now, we turn our focus to identify the process first. How to reduce the bandwidth available to a process is something which we reserve for later (i.e. That way, we can efficiently utilize the available bandwidth. So, we can just limit a process and postpone the task if we find it okay to do so. One of the advantages of tracking Bandwidth usage by process is that – We can identify the process and reason of such bandwidth usage. So, to monitor bandwidth usage by Process in Ubuntu – we can use Nethogs command-line utility. And, we don’t understand the process which is causing it. It has happened to most of us that, all of a sudden we see a spike in bandwidth usage.
