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 Ruby generally suck. (The most current post in the God mailing list? God Memory Usage Grows Steadily.)

Update: delayed_job now comes with a sample monit config based on this question.

I don't know with Monit, but I've written a couple Munin plugins to monitor Queue Size and Average Job Run Time. The changes I made to delayed_job in that patch might also make it easier for you to write Monit plugins in case you stick with that.

I had to combine the solutions on this page with another script made by toby to make it work with monit and starting with the right user.

So my delayed_job.monitrc looks like this:

check process delayed_job
  with pidfile /var/app/shared/pids/delayed_job.pid
  start program = "/bin/su -c '/usr/bin/env RAILS_ENV=production /var/app/current/script/delayed_job start' - rails"
  stop program = "/bin/su -c '/usr/bin/env RAILS_ENV=production /var/app/current/script/delayed_job stop' - rails"
