Logstash pipeline bloqued

Hi,
Actually, Im sending request to remote Logstash using Filebeat.
I have the basic configuration in both of theese tools.

I receive my requests but after a while i got this messages:

{:timestamp=>"2016-08-23T21:12:27.080000+0200", :message=>"CircuitBreaker::rescuing exceptions", :name=>"Beats input", :exception=>LogStash::Inputs::Beats::InsertingToQueueTakeTooLong, :level=>:warn}

I could not resolve it, I dont know what really block the pipeline!
Is it because input Logstash receive more much than the output ?
How can i get a graph to show the average of Logstash requests?

Thanks for help
