I have god watching delayed job and it generally works. However, when
a worker dies, it sometimes gets caught in "init" rather than
transitioning back to start. If I kill all works, stop god then
restart it, they all come back up. Any ideas?
One thing to note is that my app has a long ~15-20 sec startup.
Here's my config transitions:
w.interval = 30.seconds
w.start_grace = 20.seconds
w.restart_grace = 20.seconds
# retart if memory gets too high
w.transition(:up, :restart) do |on|
on.condition(:memory_usage) do |c|
c.above = 200.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
#c.notify = 'monitor'
end
end
# start if process is not running
w.transition(:up, :start) do |on|
on.condition(:process_running) do |c|
c.running = false
end
#on.condition(:process_exits) do |c|
# c.notify = 'monitor'
#end
end
w.lifecycle do |on|
on.condition(:flapping) do |c|
c.to_state = [:start, :restart]
c.times = 3
c.within = 10.minute
c.notify = 'monitor'
end
end
