I can't get any log output from delayed_job, and I'm not sure my jobs are starting.
Here's my Procfile:
web:     bundle exec rails server
worker:  bundle exec rake jobs:work
worker:  bundle exec clockwork app/clock.rb
And here's the job:
class ScanningJob
  def perform
    logger.info "logging from delayed_job"
  end
  def after(job)
    Rails.logger.info "logging from after delayed_job"
  end
end
I see that clockwork outputs to system out, and I can see worker executor starting, but I never see my log statements hit. I tried puts as well to no avail. 
My clock file is pretty simple:
every(3.seconds, 'refreshlistings') { Delayed::Job.enqueue ScanningJob.new }
I just want to see this working, and lack of logging means I can't. What's going on here?
