Linux provides the famous top command utility that provides us with all the information about the processes, their time, their respective IDs, how much CPU chunk they are consuming and much more. The only issue with that is the processes are not sorted in any order and the order changes frequently.
There are certain cases where we would like the output to be in a sorted manner somehow, like sorted in the sense that the process which is using the most network will be at the top.
One such command line program that we can use that will provide us the desired output is NetHogs.
NetHogs is a command line program that is used to monitor real time network traffic bandwidth used by each process or application.
yum install nethogs
sudo apt-get install nethogs
Now that we have nethogs installed we can make use of it by the commands shown below −
To execute it, it is necessary to provide the root permissions, so we run it with the sudo command as shown below −
