Can metricbeat save events to a local file for a while in case logstash or elasticsearch has problem

Elastic Stack Beats
1

Dear ESers,
I have a question, with ELK solution, We don't deploy a queuing system like rabbitMQ/redis/kafaka to hold the events yet.
if the shipper side(metricbeat) recognized logstash/elasticsearch has problem, can't sent to, can metricbeat save the events to a local file .
after logstash or ES cluster recovery from problems, and resent the events to them..

Thanks in advance.
