Smemstat – reports the physical memory usage

smemstat is a command-line tool for examining Linux process memory usage with shared memory divided proportionally, making it more informative than simple resident memory reports.

It shows swap, USS, PSS, and RSS figures for running processes, and can present memory activity either as a single snapshot or as sampled output that highlights changes over time.

This is free and open source software.

Key Features

  • Reports swap, USS, PSS, and RSS memory usage for processes.
  • Offers top-style views for memory changes and the biggest memory consumers.
  • Can monitor selected processes by PID or process name.
  • Supports JSON output for saving results for later analysis.
  • Provides short, long, basename-stripped, and comm-based command display modes.
  • Can report all user space processes when run with root privileges.
