# Nodes Info **cluster nodes info**（集群节点信息）**API** 可以获取集群中一个或多个节点的信息。 | `curl -XGET ``'[http://localhost:9200/_nodes'](http://localhost:9200/_nodes')` `curl -XGET ``'[http://localhost:9200/_nodes/nodeId1,nodeId2'](http://localhost:9200/_nodes/nodeId1,nodeId2')` | 第一个命令获取了集群中所有节点的统计信息。第二个只选择获取了 **nodeId1** 和 **nodeId2** 的节点的统计信息。所有节点选择的选项在[这里](https://www.elastic.co/guide/en/elasticsearch/reference/5.0/cluster.html#cluster-nodes)有更详细的说明。默认情况下，它只节点所有属性和核心配置 : | 属性/配置 | 描述 | | --- | --- | | build_hash | Short hash of the last git commit in this release. | | host | The node’s host name. | | http_address | Host and port where primary HTTP connections are accepted. | | ip | The node’s IP address. | | name | The node’s name. | | total_indexing_buffer | Total heap allowed to be used to hold recently indexed documents before they must be written to disk. This size is a shared pool across all shards on this node, and is controlled by [Indexing Buffer settings](https://www.elastic.co/guide/en/elasticsearch/reference/5.0/indexing-buffer.html "Indexing Buffer"). | | total_indexing_buffer_in_bytes | Same as `total_indexing_buffer`, but expressed in bytes. | | transport_address | Host and port where transport HTTP connections are accepted. | | version | Elasticsearch version running on this node. | 它也可以只获取 `**settings**，``**os**，``**process**，``**jvm**，``**thread_pool**，``**transport**，``**http**，``**plugins**，`**`ingest`**和 `**indices**的信息。` | `curl -XGET ``'[http://localhost:9200/_nodes/process'](http://localhost:9200/_nodes/process')` `curl -XGET ``'[http://localhost:9200/_nodes/_all/process'](http://localhost:9200/_nodes/_all/process')` `curl -XGET ``'[http://localhost:9200/_nodes/nodeId1,nodeId2/jvm,process'](http://localhost:9200/_nodes/nodeId1,nodeId2/jvm,process')` `# same as above` `curl -XGET ``'[http://localhost:9200/_nodes/nodeId1,nodeId2/info/jvm,process'](http://localhost:9200/_nodes/nodeId1,nodeId2/info/jvm,process')` `curl -XGET 'http:``//localhost``:9200``/_nodes/nodeId1``,nodeId2``/_all` | 可以设置 **_all** 标记以返回所有的信息 - 或者您也可以简单的忽略它。 ## Operating System information（操作系统信息）可以设置 **os** 标记以获取与操作系统有关的信息 : | 标记 | 描述 | | --- | --- | | os.refresh_interval_in_millis | Refresh interval for the OS statistics | | os.name | Name of the operating system (ex: Linux, Windows, Mac OS X) | | os.arch | Name of the JVM architecture (ex: amd64, x86) | | os.version | Version of the operating system | | os.available_processors | Number of processors available to the Java virtual machine | | os.allocated_processors | The number of processors actually used to calculate thread pool size. This number can be set with the `processors` setting of a node and defaults to the number of processors reported by the OS. In both cases this number will never be larger than 32. | ## Process information（进程信息）可以设置 **process **标记以获取与当前正在运行的进程的有关的信息 : | 标记 | 描述 | | --- | --- | | process.refresh_interval_in_millis | Refresh interval for the process statistics | | process.id | Process identifier (PID) | | process.mlockall | Indicates if the process address space has been successfully locked in memory | ## Plugins information（插件信息） **`plugins`**- 如果被设置，那么结果将包含关于每一个节点已加载的插件的详细信息 : * **`name`**: plugin name * **`description`**: plugin description if any * **`site`**: `true` if the plugin is a site plugin * **`jvm`**: `true` if the plugin is a plugin running in the JVM * **`url`**: URL if the plugin is a site plugin 其结果看起来和下面相似 : | `{` `"cluster_name"` `: ``"test-cluster-MacBook-Air-de-David.local"``,` `"nodes"` `: {` `"hJLXmY_NTrCytiIMbX4_1g"` `: {` `"name"` `: ``"node4"``,` `"transport_address"` `: ``"inet[/172.18.58.139:9303]"``,` `"hostname"` `: ``"MacBook-Air-de-David.local"``,` `"version"` `: ``"0.90.0.Beta2-SNAPSHOT"``,` `"http_address"` `: ``"inet[/172.18.58.139:9203]"``,` `"plugins"` `: [ {` `"name"` `: ``"test-plugin"``,` `"description"` `: ``"test-plugin description"``,` `"site"` `: ``true``,` `"jvm"` `: ``false` `}, {` `"name"` `: ``"test-no-version-plugin"``,` `"description"` `: ``"test-no-version-plugin description"``,` `"site"` `: ``true``,` `"jvm"` `: ``false` `}, {` `"name"` `: ``"dummy"``,` `"description"` `: ``"No description found for dummy."``,` `"url"` `: ``"/_plugin/dummy/"``,` `"site"` `: ``false``,` `"jvm"` `: ``true` `} ]` `}` `}` `}` | ## Ingest information（摄取数据信息） **ingest** - 如果被设置，那么结果将包含关于每一个节点可用的处理器的详细信息 : * **`type`**: the processor type 其结果看起来和下面相似 : | `{` `"cluster_name"``: ``"elasticsearch"``,` `"nodes"``: {` `"O70_wBv6S9aPPcAKdSUBtw"``: {` `"ingest"``: {` `"processors"``: [` `{` `"type"``: ``"date"` `},` `{` `"type"``: ``"uppercase"` `},` `{` `"type"``: ``"set"` `},` `{` `"type"``: ``"lowercase"` `},` `{` `"type"``: ``"gsub"` `},` `{` `"type"``: ``"convert"` `},` `{` `"type"``: ``"remove"` `},` `{` `"type"``: ``"fail"` `},` `{` `"type"``: ``"foreach"` `},` `{` `"type"``: ``"split"` `},` `{` `"type"``: ``"trim"` `},` `{` `"type"``: ``"rename"` `},` `{` `"type"``: ``"join"` `},` `{` `"type"``: ``"append"` `}` `]` `}` `}` `}` `}` |
