How do I find the process generating a lot of network traffic?

Use iftop to locate the TCP port on your machine that is receiving the most traffic. Then use sudo netstat -tup to locate the process owning that port.

A very simple approach then is to periodically look in /proc/<PID>/net/dev and store it with a timestamp. Here you can get total packets/bytes sent from a PID.

I'm looking for a way to log the network traffic of a single Linux process (on Ubuntu, but will look at other flavours too).

NetHogs is a text-based network traffic monitoring tool that displays bandwidth usage by each process or application running on a Linux system.

I want to monitor and log all traffic that a specific process produces. I know about tcpdump , but it seems it doesn't support filtering by process.

My machine is generating a lot of network traffic, all from the same source port, with many different destinations (found this out by running iftop -P , and ...

In Linux, you can view network traffic metrics by using various utilities, such as System Activity Reporter (SAR), iftop, and nethogs.

In this tutorial, we'll explore various ways to capture the network traffic of a process in Linux.

I was hoping to add a tab to resource monitor that would show the application that's using the network and how much bandwidth.

The vnstat command is a popular tool for monitoring network traffic on Linux servers. vnstat provides network statistics about specific network interfaces in ...
