- Remove the worker class name from class_names.rb
- Start your sever normally
- Make sure your provider is added to your appliance (for provider-specific workers like refreshers and event catchers)
- Run rails console (see rails script below)

| worker_class = ManageIQ::Providers::Openstack::CloudManager::EventCatcher | |
| runner_class = worker_class::Runner | |
| worker = worker_class.create_worker_record | |
| runner_cfg = {:guid => worker.guid, :ems_id => "25"} | |
| runner = runner_class.new(runner_cfg) | |
| runner.start |
You could then simulate the DRb messages to send to the worker, etc.
Removal of worker class name from class_names.rb is supposed to prevent the worker from being started, right?
I can't get this expected behavior. I removed the 2 lines of the same worker. I also added a log line to the worker I'm removing. What I had expected was that the log line I added will be gone from evm.log. However, it is still there in evm.log. My 3 lines code change is here
What I would like to do is to start the subject worker in rails console in order to debug it. Thanks for your help.
Anybody know of a way to debug workers that currently works?
@NickLaMuro @jrafanie @carbonin ?
Oh this script works now, yay! 🎉

It would be nice to be able to run this without a server by injecting the server's zone, server's drb, ignore the worker monitor status, etc. Also, I don't know that we really NEED the worker row (eliminate the create_worker_record). That would eliminate some of this work like modifying the class names and make it much easier to instantiate and test in specs.
That would enable us to instantiate
