NetHogs

If you wish to monitor the top bandwidth consuming processes on a Linux system, you can use the nethogs program, which displays bandwidth usage by process. It will display the process id (PID) of the processes consuming the most bandwidth. E.g.:

NetHogs version 0.8.5

    PID USER     PROGRAM                    DEV        SENT      RECEIVED       
  19355 jim      sshd: jim@pts/0            enp1s4      0.188       0.082 KB/sec
  15022 apache   /usr/sbin/httpd            enp1s4      0.000       0.000 KB/sec
      ? root     unknown TCP                            0.000       0.000 KB/sec

  TOTAL                                                 0.188       0.082 KB/sec

The above output shows me that the two processes consuming the most bandwidth at the time the program was run had PIDs of 19355 and 15022. I can get additional information on those processes using the ps command.

$ ps 19355
  PID TTY      STAT   TIME COMMAND
19355 ?        S      0:19 sshd: jim@pts/0
$ ps 15022
  PID TTY      STAT   TIME COMMAND
15022 ?        S      0:00 /usr/sbin/httpd -DFOREGROUND
$
