How to monitor delayed_job with monit

Question

Are there any examples on the web of how to monitor delayed_job with Monit?

Everything I can find uses God, but I refuse to use God since long running processes in

I found it was easier to create an init script for delayed job. It is available here: http://gist.github.com/408929 or below:

#! /bin/sh
set_path="cd /home/rails/evatool_staging/current"

case "$1" in
  start)
        echo -n "Starting delayed_job: "
                su - rails -c "$set_path; RAILS_ENV=staging script/delayed_job start" >> /var/log/delayed_job.log 2>&1
        echo "done."
        ;;
  stop)
        echo -n "Stopping sphinx: "
                su - rails -c "$set_path; RAILS_ENV=staging script/delayed_job stop" >> /var/log/delayed_job.log 2>&1
        echo "done."
        ;;
      *)
            N=/etc/init.d/delayed_job_staging
            echo "Usage: $N {start|stop}" >&2
            exit 1
            ;;
    esac

    exit 0

Then make sure that monit is set to start / restart the app so in your monitrc file:

check process delayed_job with pidfile "/path_to_my_rails_app/shared/pids/delayed_job.pid"
start program = "/etc/init.d/delayed_job start"
stop program = "/etc/init.d/delayed_job stop"

and that works great!
