Nodes Info · my-elasticsearch-cn

# Nodes Info **cluster nodes info**（集群節點信息）**API**?可以獲取集群中一個或多個節點的信息。 | `curl -XGET?``'[http://localhost:9200/_nodes'](http://localhost:9200/_nodes')` `curl -XGET?``'[http://localhost:9200/_nodes/nodeId1,nodeId2'](http://localhost:9200/_nodes/nodeId1,nodeId2')` | 第一個命令獲取了集群中所有節點的統計信息。第二個只選擇獲取了?**nodeId1**?和?**nodeId2**?的節點的統計信息。所有節點選擇的選項在[這里](https://www.elastic.co/guide/en/elasticsearch/reference/5.0/cluster.html#cluster-nodes)有更詳細的說明。默認情況下，它只節點所有屬性和核心配置 :? | 屬性/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. | 它也可以只獲取?`**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` | 可以設置?**_all**?標記以返回所有的信息 - 或者您也可以簡單的忽略它。 ## Operating System information（操作系統信息）可以設置?**os**?標記以獲取與操作系統有關的信息 :? | 標記 | 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（進程信息）可以設置?**process?**標記以獲取與當前正在運行的進程的有關的信息 :? | 標記 | 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`**- 如果被設置，那么結果將包含關于每一個節點已加載的插件的詳細信息 :? * **`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 其結果看起來和下面相似 :? | `{` `"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（攝取數據信息） **ingest**?-?如果被設置，那么結果將包含關于每一個節點可用的處理器的詳細信息 :? * **`type`**: the processor type 其結果看起來和下面相似 :? | `{` `"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"` `}` `]` `}` `}` `}` `}` |
