Details

To find more information about the process:

  • Find the ID of the process using the ps command e.g. the ID of the following process is 1974:

    openerp   1974  0.4 34.7 502328 358976 ?       Sl   Mar21 280:15 /usr/bin/python ./openerp-server.py --config=/etc/openerp-server.conf --price_accuracy=4

  • Change into the proc folder for the process e.g:

    cd /proc/1974/

  • The folder has lots of files representing really useful information e.g:

    -r--r--r--  1 openerp nogroup 0 2010-04-30 15:40 cmdline
-rw-r--r--  1 openerp nogroup 0 2010-04-30 15:39 coredump_filter
-r--r--r--  1 openerp nogroup 0 2010-04-30 15:39 cpuset
lrwxrwxrwx  1 openerp nogroup 0 2010-04-30 15:39 cwd -> /usr/lib/openerp-server
-r--------  1 openerp nogroup 0 2010-04-30 15:39 environ
lrwxrwxrwx  1 openerp nogroup 0 2010-04-30 15:39 exe -> /usr/bin/python2.5

    • cwd is the current working folder for the process.

    • exe is the running executable.

    • if we cat the cmdline or environ files we can see the command line and environment.

    • ls -l fd will show file descriptors (I think).

  • To view all files and ports open by the process, pass the process ID to the lsof command:

    lsof -p 1974
