查看當前集群全部健康指標的信息，執行如下命令：

curl -X GET "https://localhost:9200/_health_report?pretty" --cacert $ES_HOME/config/certs/http_ca.crt -u "elastic:ohCxPH=QBE+s5=*lo7F9"

執行結果輸出如下：

查看當前集群健康指標比如shards_availability的信息，執行如下命令：

curl -X GET "https://localhost:9200/_health_report/shards_availability?pretty" --cacert $ES_HOME/config/certs/http_ca.crt -u "elastic:ohCxPH=QBE+s5=*lo7F9"

執行結果輸出如下：

{"cluster_name" : "elasticsearch","indicators" : {"shards_availability" : {"status" : "green","symptom" : "This cluster has all shards available.","details" : {"initializing_primaries" : 0,"restarting_primaries" : 0,"started_primaries" : 1,"unassigned_replicas" : 0,"initializing_replicas" : 0,"creating_primaries" : 0,"restarting_replicas" : 0,"unassigned_primaries" : 0,"started_replicas" : 0,"creating_replicas" : 0}}}
}

目前支持的指標：

• master_is_stable
• shards_availability
• disk
• ilm，即Indexing Lifecycle Management
