Is it possible to monitor jruby program using God ruby gem ? Any working example will be helpful. Here is what I've tried so far but it doesn't work.
Here is the God file start_app.god
God.watch do |w|
w.name = "simple"
w.start = "jruby /path/to/my_jruby/my_jruby.rb"
w.keepalive
end
Here is the logs when I run god -c start_app.god -D

Notice the statement simple moved 'start' to 'up' keeps on repeating itself meaning god couldn't start the my_jruby.rb script.
Anyone who knows the cause of this issue? If can't accomplish this using God, what are the possible alternatives?
