senlin-engine stuck cleaning up

I'm installing the Stein version of Senlin following the guide at https://docs.openstack.org/senlin/ste.... When I get to the step to run "senlin-engine --config-file /etc/senlin/senlin.conf" it goes along very nicely until it gets to "Finished cleaning up dead services." and then it just stops. After waiting several (5-10) minutes, I finally press Ctrl-C to get my CLI prompt back.

The next command, "senlin-api --config-file /etc/senlin/senlin.conf" fails trying to connect to "0.0.0.0:8778. I believe there is missing somewhere an instruction to change that to "<host>" (substituting the actual name of my Controller), but where is that change to be made?

The senlin-engine is not stuck. The senlin-engine is a service that just sits there and waits for requests from the senlin-api. So if no API requests are made, nothing will be printed out.

Thanks! Where is Senlin usage documented? I feel like I should have been able to discover that answer on my own.

The guide says

You may need two consoles for the services i.e., one for each service.

This is a hint that you can't use those terminals for anything else. Yes, it could be stated more explicitly.

Thanks to dtruong, I decided that perhaps not being able to figure out how to use Senlin directly was not so bad, since my objective was and is to evaluate Heat. So I proceeded with the Heat installation, which actually seems to work. So it appears that Senlin is working correctly, I just didn't interpret correctly the behavior of the senlin-engine command.
