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
ps_mem.py.
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
situation.
Classic Rust:
git clone https://github.com/bpowers/psm2
cd psm
cargo build --release
sudo make install
bpowers@python-worker-01:~$ psm -filter=celery

The MB RAM column is the sum of the Pss value of each mapping in
/proc/$PID/smaps for each process.
