Is there any way in ruby to determine if a background worker is running?
For instance, i have a server that works a queue in delayed job and i would like to ensure 4 workers are on it and spin up a new worker process if one has either stalled or quit.
From the command line, crontab -lgives a list of all currently running jobs.
From the Rails console, Delayed::Job.all will give you a list of all currently running jobs.
Delayed Job also has a list of lifecycle methods which you can access:
