ElasticSearch之Nodes info API

查看当前集群中各节点的信息，执行如下命令：

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

本接口允许指定节点和指标。

当前支持的指标，如下：

• aggregations
• http
• indices
• ingest
• jvm
• os
• plugins
• process
• settings
• thread_pool
• transport

指定指标时的命令样例：

• 查看jvm的参数。

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

• 查看process和thread_pool的参数。

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

默认情况下，如果不指定具体的节点或者指标，本接口会返回全部信息，数据量比较大，执行结果输出如下：
