Thank you both for your answers, I'll update to Logstash 5.4.0, the persistent input queue are now GA! And normally it will be able to handle burst. Plus I'll be able to see the input queue status via the Logstash API.
I'll keep you informed.

I'm not sure how much this will matter, as logstash doesn't have any internal queueing, so the normal strategy of sending a burst of traffic to one, disconnecting and reconnecting to let the load balancer work and send another burst of traffic may not really work as the logstash instances have no way of taking a bust and working through the backlog. look at your logstash instances and you will probably find that one is maxed out.
