ElasticSearch之Index stats API

获取指定索引的统计数据。

获取指定索引的全部统计数据，命令样例如下：

curl -X GET "https://localhost:9200/testindex_001/_stats?pretty" --cacert $ES_HOME/config/certs/http_ca.crt -u "elastic:ohCxPH=QBE+s5=*lo7F9"

执行结果的样例，如下：

获取指定索引的指定指标的统计数据，命令样例如下：

curl -X GET "https://localhost:9200/testindex_001/_stats/completion?pretty" --cacert $ES_HOME/config/certs/http_ca.crt -u "elastic:ohCxPH=QBE+s5=*lo7F9"

执行结果的样例，如下：

{
  "_shards" : {
    "total" : 2,
    "successful" : 1,
    "failed" : 0
  },
  "_all" : {
    "primaries" : {
      "completion" : {
        "size_in_bytes" : 0
      }
    },
    "total" : {
      "completion" : {
        "size_in_bytes" : 0
      }
    }
  },
  "indices" : {
    "testindex_001" : {
      "uuid" : "7iGJRFfxRd2jD3qP-KDRmQ",
      "health" : "yellow",
      "status" : "open",
      "primaries" : {
        "completion" : {
          "size_in_bytes" : 0
        }
      },
      "total" : {
        "completion" : {
          "size_in_bytes" : 0
        }
      }
    }
  }
}

允许指定的指标，如下：

• _all，默认值，即全部指标，无需显式指定。
• completion
• docs
• fielddata
• flush
• get
• indexing
• merge
• query_cache
• refresh
• request_cache
• search
• segments
• store
• translog

方法参数
