系统信息处理程序

此 API 提供仪表板上显示的相同信息。

系统信息可通过两个不同的 URL 获得

http://localhost:8983/solr/admin/system

和

http://localhost:8983/solr/<collection-name>/admin/system

唯一的区别是填充结果中的core键。

结果中的键是

模式: solrcloud或std，指示 Solr 运行的模式
lucene: 包含 Solr 和 Lucene 版本信息的对象
jvm: 包含 JVM 信息的对象
系统: 系统信息。
solr_home: Solr 基本目录。仅在/solr/admin/system下可用。
zkHost: 在云模式下运行时的 Zookeeper 主机。
节点: 在云模式下运行时的节点名称。
核心: 包含核心基本信息的对象，仅在提供核心/集合名称时出现

Lucene 和 Solr 信息对象

响应中的solr键是一个包含以下键的对象

lucene-spec-version: Lucene 包的规范版本。
lucene-impl-version: Lucene 包的实现版本。
solr-spec-version: Solr 包的规范版本。
solr-impl-version: Solr 包的实现版本。

JVM 信息对象

响应中的jvm键是一个包含以下键及更多键的对象

版本: JVM 规范版本。
名称: JVM 名称。
内存: 包含内存使用情况信息的对象。

系统信息对象

响应中的system键是一个包含以下键及更多键的对象

名称: 操作系统名称。
uname: 运行 uname -a 的结果。Windows 上不可用。
正常运行时间: 运行 uptime 的结果。Windows 上不可用。

核心信息对象

模式: 模式名称。
主机: 主机名。不可用时为 null。
开始: 核心启动时间。
现在: 核心主机上的当前时间。
目录: 与核心相关的目录对象。

系统信息 API 示例

从云模式中的节点检索系统信息。
