Incorrect number of processes
Hi, I get this:
1.9 GiB + 16.0 MiB = 1.9 GiB ruby (40)
for my ruby processes but when I run ps aux | grep ruby | wc -l, I get 24, not 40... also it looks like this (a lot of defunct processes)
$ ps aux | grep ruby

what gives?
ps aux gives a truncated command name. Perhaps this gives a better count?
ps -e -o args | grep ruby
It gives the same number (24)

Do you get the same number when running as root?
sudo ps -e -o args | grep ruby
Also does splitting command line arguments give a better indication of where the ruby processes are comming from?
sudo ps_mem -s | grep ruby
All I can suggest is to add some instrumentation to getCmdName(). Something like:
if cmd == 'ruby':
print pid, cmd, " ".join(cmdline)
That will show the pids at least and you can see details in /proc/$pid
Thank you, it's getting clearer now...
Still not sure what is happening but I guess there really are that many processes (I have some fail it looks like but I'll deal with it separatelly)

Still not sure still why ps reports less (35 now) ?
Can you see something from that inspection?
thank you

Hmm do you think the difference is here:
david 28184 0.0 0.4 161780 16844 ? Sl 2014 8:49 puma
2.9.2 (unix:///var/www/voter/shared/tmp/sockets/puma.sock,tcp://0.0.0.0:3009 )
vs
ruby puma 2.9.2
(unix:///var/www/voter/shared/tmp/sockets/puma.sock,tcp://0.0.0.0:3009)
plus this:

so you get more info (the whole command line?) versus just part in ps......
That's it!

I thought the -s option to ps_mem might have split those out sufficiently. It would be bad if ps_mem was lumping all ruby apps together for example
Looks like your -s option could be improved because it doesn't operate on the same command line strings as your grouping function... that's why it didn't return ruby spring and ruby puma stuff when I tried it... your debug code did.
@davidhq @cybernet please check if https://github.com/pixelb/ps_mem/pull/75 fixed it :)
