Elasticsearch(es)查看集群所有索引情况

Elasticsearch(es)集群运维可视化监控工具及核心指标 Elasticsearch(es)集群运维可视化监控工具及核心指标


Elasticsearch(es)查看集群中所有索引情况可以使用 cat API 查看,其中索引相关的接口是 _cat/indices

几种方式

可以在终端执行 curl 命令或在 es 工具上执行 get 请求(如 kibana 的 dev tools)。

curl 命令

curl -XGET 'localhost:9200/_cat/indices?v&pretty'

Kibana Dev Tools 上执行

GET _cat/indices?v&s=index:asc

其中参数 v 全称是 verbose,表示返回详细的输出;s 参数表示进行排序(sort),形式 s=column1,column2:<desc/asc>

返回信息如下:

health status index                          uuid                   pri rep docs.count docs.deleted store.size pri.store.size

......

返回信息的第一行对应的每一列字段意义如下:

health
当前健康状态
status
开启/关闭(open/close)状态
index
索引名称
uuid
索引 uuid
pri
主分片数目
rep
副本分片数目
docs.count
可用的文档数目
docs.deleted
已删除的文档数目
store.size
主分片和副本分片的存储文档空间大小
pri.store.size
主分片的存储文档空间大小

关于列字段的更多内容,也可以通过增加 help 参数进行查看。

GET _cat/indices?help

输出如下:
