17-十七、Elasticsearch 教程: 集群管理 API

本章节要介绍的这些 API 用于获取有关集群及其节点的信息,并且可以对集群进行更改

调用这些 API 时,我们需要指定节点的名称、地址或使用 _local 路径参数

例如下面的请求


GET http://localhost:9200/_nodes/_local

会返回本地集群的信息

或者使用下面的查询返回 127.0.0. 节点的信息


GET http://localhost:9200/_nodes/127.0.0.1

返回的内容和上面的一样

集群健康情况

可以在集群信息上追加 health 路径参数来查询集群的健康情况

例如下面的查询


GET http://localhost:9200/_cluster/health

返回内容如下


{ "cluster_name": "elasticsearch", "status": "yellow", "timed_out": false, "number_of_nodes": 1, "number_of_data_nodes": 1, "active_primary_shards": 20, "active_shards": 20, "relocating_shards": 0, "initializing_shards": 0, "unassigned_shards": 20, "delayed_unassigned_shards": 0, "number_of_pending_tasks": 0, "number_of_in_flight_fetch": 0, "task_max_waiting_in_queue_millis": 0, "active_shards_percent_as_number": 50 }

集群状态

这个 API 通过在 URL 上追加 state 路径参数来获取有关集群的状态信息

状态信息包含版本,主节点,其他节点,路由表,元数据和块

例如下面的请求


GET http://localhost:9200/_cluster/state

响应内容如下


{ "cluster_name": "elasticsearch", "status": "yellow", "timed_out": false, "number_of_nodes": 1, "number_of_data_nodes": 1, "active_primary_shards": 20, "active_shards": 20, "relocating_shards": 0, "initializing_shards": 0, "unassigned_shards": 20, "delayed_unassigned_shards": 0, "number_of_pending_tasks": 0, "number_of_in_flight_fetch": 0, "task_max_waiting_in_queue_millis": 0, "active_shards_percent_as_number": 50 }

集群统计信息

此 API 通过在 URL 上追加 stats 关键字来检索有关集群的统计信息

返回的内容包括分片编号,存储大小,内存使用情况,节点数,角色,操作系统和文件系统

例如下面的请求


GET http://localhost:9200/_cluster/stats

响应内容如下
