Logstash导入数据后，Cerebro显示集群health的状态为yellow

 

解决办法

curl http://localhost:9200/_cat/indices\?v

 

curl http://localhost:9200/_cluster/health?pretty=true

 

curl -H "Content-Type: application/json" -XPUT 'http://localhost:9200/_settings' -d '
{
    "index" : {
        "number_of_replicas" : 0
    }
}'

 

curl http://localhost:9200/_cluster/health?pretty=true

 

再次查看Cerebro，health的状态为green
