ps_mem

A utility to accurately report the core memory usage for a program

Yes the name is a bit weird. coremem would be more appropriate, but for backwards compatible reasons the ps_mem name remains.

Usage:

ps_mem [-h|--help] [-s|--split-args] [-p PID] [-w N]

Example output:

 Private  +   Shared  =  RAM used       Program

 34.6 MiB +   1.0 MiB =  35.7 MiB       gnome-terminal

139.8 MiB +   2.3 MiB = 142.1 MiB       firefox

291.8 MiB +   2.5 MiB = 294.3 MiB       gnome-shell

272.2 MiB +  43.9 MiB = 316.1 MiB       chrome (12)

913.9 MiB +   3.2 MiB = 917.1 MiB       thunderbird

---------------------------------

                          1.9 GiB

=================================

The [-p PID] option allows filtering the results. For example to restrict output to the current $USER you could:

sudo ps_mem -p $(pgrep -u $USER | paste -d, -s)

自己测试一下生产系统的服务器：

# ./ps_mem.py

 Private  +   Shared  =  RAM used       Program

  4.0 KiB +   9.5 KiB =  13.5 KiB       acpid

  4.0 KiB +  10.5 KiB =  14.5 KiB       portreserve

  4.0 KiB +  25.0 KiB =  29.0 KiB       abrt-dump-oops

  4.0 KiB +  28.0 KiB =  32.0 KiB       xinetd

 12.0 KiB +  29.5 KiB =  41.5 KiB       mingetty (3)

 32.0 KiB +  26.5 KiB =  58.5 KiB       atd

204.0 KiB +  55.0 KiB = 259.0 KiB       automount

248.0 KiB +  31.0 KiB = 279.0 KiB       init

288.0 KiB +  75.0 KiB = 363.0 KiB       udevd (3)

420.0 KiB +  41.0 KiB = 461.0 KiB       rsyslogd

496.0 KiB + 176.0 KiB = 672.0 KiB       ksmtuned

自己对这些不是很了解，不知道是否正确！
