Upstart monitoring problems in ubuntu and creating a pid -


i looking how create pid file monitoring of upstart processes in ubuntu. looked @ accepted answer in ubuntu, upstart, , creating pid monitoring , ended following code:

env program_name=myscript env base_path=/bar/  respawn limit 5 30  script ${base_path}/bin/python ${base_path}/scripts/${program_name}.py -e ${base_path}/foo.ini end script  post-start script echo pid=`status myscript | egrep -oi '([0-9]+)$' | head -n1`  echo $pid > /var/run/${program_name}.pid end script  post-stop script rm -f /var/run/${program_name}.pid end script

there 3 problems encounter:

  1. somehow code creates 2 processes. parent process (checked through ps -ef | grep python) shell such as:

    /bin/sh -e -c ${base_path}/bin/python ${base_path}/scripts/${program_name}.py -e ${base_path}/foo.ini /bin/sh

    while child process has correct substitutes:

    /bar/bin/python /bar/scripts/myscript.py -e /bar/foo.ini

  2. the pid file contains pid of parent of actual process. not child 1 actual process.

  3. the respawn doesn't work. kill child process kill pid (which kills parent too, not vice versa).

Why does Ruby on Rails generate add a blank line to the end of a file? -
