系統資訊處理器

此 API 提供與儀表板上顯示的相同資訊。

系統資訊可透過兩個不同的 URL 取得

https://127.0.0.1:8983/solr/admin/system

和

https://127.0.0.1:8983/solr/<collection-name>/admin/system

唯一的差異在於在結果中填入 core 鍵。

結果中的鍵為

mode: solrcloud 或 std，表示 Solr 執行的模式
lucene: 包含 Solr 和 Lucene 版本資訊的物件
jvm: 包含 JVM 相關資訊的物件
system: 系統相關資訊。
solr_home: Solr 基礎目錄。僅在 /solr/admin/system 下可用。
zkHost: 在雲端模式下執行時的 Zookeeper 主機。
node: 在雲端模式下執行時的節點名稱。
core: 包含核心基本資訊的物件，僅在提供核心/集合名稱時存在

Lucene 和 Solr 資訊物件

回應中的 solr 鍵是一個包含這些鍵的物件

lucene-spec-version: Lucene 套件的規格版本。
lucene-impl-version: Lucene 套件的實作版本。
solr-spec-version: Solr 套件的規格版本。
solr-impl-version: Solr 套件的實作版本。

JVM 資訊物件

回應中的 jvm 鍵是一個包含這些鍵和其他鍵的物件

version: JVM 規格版本。
name: JVM 的名稱。
memory: 包含記憶體使用資訊的物件。

系統資訊物件

回應中的 system 鍵是一個包含這些鍵和其他鍵的物件

name: 作業系統名稱。
uname: 執行 uname -a 的結果。在 Windows 上不可用。
uptime: 執行 uptime 的結果。在 Windows 上不可用。

核心資訊物件

schema: 結構描述名稱。
host: 主機名稱。如果不可用則為 null。
start: 核心啟動時間。
now: 核心主機上的目前時間。
directory: 包含與核心相關目錄的物件。

系統資訊 API 範例

從雲端模式下的節點擷取系統資訊。
