ElasticSearch之Index stats API

本文主要是介绍ElasticSearch之Index stats API，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

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：

{"_shards" : {"total" : 2,"successful" : 1,"failed" : 0},"_all" : {"primaries" : {"docs" : {"count" : 0,"deleted" : 0},"shard_stats" : {"total_count" : 1},"store" : {"size_in_bytes" :

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}}}}
