Hi all
Is there a way to make god doesn't setup a process if it throws an
exception?
We use god to start some resque workers and sometimes, one of the workers
throws an exception, and they doesn't start, but god says that the process
is 'up', when actually, there are no workers running.
here is my .god file
num_workers.times do |num|
God.watch do |w|
w.dir = "#{rails_root}"
w.name = "resque-#{num}"
w.group = 'resque'
w.interval = 5.seconds
w.env = {"QUEUE"=>"*", "RAILS_ENV"=>rails_env}
w.start = "/usr/bin/rake -f #{rails_root}/Rakefile environment
resque:work"
#w.uid = 'server'
#w.gid = 'server'
# restart if memory gets too high
w.transition(:up, :restart) do |on|
on.condition(:memory_usage) do |c|
c.above = 350.megabytes
c.times = 2
end
end
# determine the state on startup
w.transition(:init, { true => :up, false => :start }) do |on|
on.condition(:process_running) do |c|
c.running = true
end
end
# determine when process has finished starting
w.transition([:start, :restart], :up) do |on|
on.condition(:process_running) do |c|
c.running = true
c.interval = 5.seconds
end
# failsafe
on.condition(:tries) do |c|
c.times = 5
c.transition = :start
c.interval = 5.seconds
end
end
# start if process is not running
w.transition(:up, :start) do |on|
on.condition(:process_running) do |c|
c.running = false
end
end
end
