psm - simple, accurate memory reporting for Linux
psm makes it easy to see who is resident in memory, and who is
significantly swapped out.
psm is based off the ideas and implementation of
It requires root privileges to run. It is implemented in Rust, and
since the executable is a binary it can be made setuid root so that
unprivileged users can get a quick overview of the current memory
