What should I do with Logstash when ES is died?

Elastic Stack Logstash

Hi guys,

I'm using Logstash to give logs of Kafka and send to ES but I have a problem that when ES is died, Logstash can't send data to ES, those data will be lost in this time. So what should I do to make sure data isn't lost when ES is died?

Thanks.

If Logstash can't sent to ES it'll stop consuming messages from Kafka. Why do you think you'd lose anything?
