[Solved] View process RAM usage in human readable form

Midasx · 2013-01-29 17:50:15

I would like to see a list of current proesses and the amount of RAM they are using sorted by the RAM usage. i.e.

100MB's openbox
50MB's firefox
etc...

I can use htop to view RAM % but not MB's (To my knowledge). Is there a program to do this?

Thanks

This python script is quite useful :
http://www.pixelbeat.org/scripts/ps_mem.py

execute it like this:

$ sudo python scriptname

Have you tried changing the memory column to something more useable in htop?

F2 -> Columns -> M_RESIDENT and M_SIZE?
I've got:

  PID USER      PRI  NI  VIRT   RES   SHR S CPU% MEM%   TIME+  Command
  518 root       20   0  176M 78340 46984 R 25.4  0.5  7:52.26 /usr/bin/X 
3030  user       20   0  590M  106M 42900 S 25.4  0.7  2:49.20 /usr/lib/chromiu

WHere RES shows M for Mb of ram?
IIRC htop converts bytes to Kb (not KB) automatically if the bytes exceeds 1024, and if that exceeds it converts to Mb and so on.

I seem to get a syntax error with that script

./ps_mem.py 
  File "./ps_mem.py", line 138
    except getopt.GetoptError, e:
                             ^
SyntaxError: invalid syntax

I had a tinker with htop settings but nothing gave me a clear display unfortunately. I did get to tweak some settings though

Here is the version of the script I am using :
http://pastebin.com/8pKtGtyk
Execute it like I posted.

while read command percent rss; do
  if [[ "${command}" != "COMMAND" ]]; then
    rss="$(bc <<< "scale=2;${rss}/1024")";
  fi; 
  printf "%-26s%-8s%s\n" "${command}" "${percent}" "${rss}";
done < <(ps -A --sort -rss -o comm,pmem,rss | sed -n 1,11p)

Example output:

COMMAND                   %MEM    RSS
firefox                   32.4    323.56
urxvtd                    2.4     24.24
mplayer                   1.8     18.50
plugin-containe           1.8     18.23
X                         1.3     13.12
vim                       0.4     4.67
bash                      0.2     2.85
bash                      0.2     2.84
bash                      0.2     2.84
bash                      0.2     2.83

You can tweak it to show all processes, not just the top ten, omit %MEM etc.
