nethogs
A Linux 'net top' tool that groups network bandwidth usage by process instead of protocol or subnet.
What is nethogs?
NetHogs is a command-line network monitoring tool for Linux that displays real-time network bandwidth usage grouped by process. It solves the problem of identifying which specific application or process is consuming network resources, especially useful when diagnosing unexpected traffic spikes or bandwidth hogs.
System administrators, DevOps engineers, and Linux users who need to monitor and troubleshoot network usage at the process level on Linux systems.
Developers choose NetHogs for its unique process-centric view of network traffic, its lightweight design requiring no kernel modules, and its immediate visibility into bandwidth-hungry applications without complex setup.
