Logstash導入數據後，Cerebro顯示集羣health的狀態爲yellow

 

解決辦法

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

 

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

 

1 curl -H "Content-Type: application/json" -XPUT 'http://localhost:9200/_settings' -d '
2 {
3     "index" : {
4         "number_of_replicas" : 0
5     }
6 }'

 

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

 

再次查看Cerebro，health的狀態爲green
