hi there!

let me describe my scenario first.

i'm streaming `application logs` to `logstash` host using TCP input plugin, then inject to `AWS ES domain`.  
what will happened when elasticsearch cluster status is red?  
will it impact on application performance?

plz, guide to me 🙂

Hey,

please see

[https://www.elastic.co/guide/en/elasticsearch/reference/6.1/cluster-health.html](https://www.elastic.co/guide/en/elasticsearch/reference/6.1/cluster-health.html)  
[https://www.elastic.co/guide/en/elasticsearch/reference/6.1/\_cluster\_health.html](https://www.elastic.co/guide/en/elasticsearch/reference/6.1/_cluster_health.html)

This is less of an impact of performance but more about missing data when executing a search, which is as important.
