3.6.6. 用管理 CLI 显示可用资源

过程 3.18. 在管理 CLI 里执行命令

1. 运行 read-resource 操作

   在管理 CLI 里，请用 read-resource 操作来显示可用的资源。

   [standalone@localhost:9999 /]:read-resource

   下面的例子展示了在独立服务器里如何使用 read-resource 操作来开放普通资源信息。结果类似于 standalone.xml 配置文件，显示系统资源、扩展、接口和为服务器实例安装和配置的子系统。它们可以进一步进行直接查询。

   例 3.11. 在根级别使用 read-resource 操作

   [standalone@localhost:9999 /]:read-resource

2. 针对子节点运行 read-resource 操作

   read-resource 操作可以查询根节点的子节点。操作的结构首先定义要开放的节点，然后附加这个操作来运行。

   [standalone@localhost:9999 /]/subsystem=web/connector=http:read-resource

   Copy to Clipboard Toggle word wrap
   在下面的例子里，通过指引 read-resource 操作到专有的 Web 子系统节点来开放 Web 子系统组件的专有资源信息。

   例 3.12. 开放根结点的子节点资源

   [standalone@localhost:9999 /] /subsystem=web/connector=http:read-resource                      
   {
       "outcome" => "success",
       "result" => {
           "configuration" => undefined,
           "enable-lookups" => false,
           "enabled" => true,
           "executor" => undefined,
           "max-connections" => undefined,
           "max-post-size" => 2097152,
           "max-save-post-size" => 4096,
           "name" => "http",
           "protocol" => "HTTP/1.1",
           "proxy-name" => undefined,
           "proxy-port" => undefined,
           "redirect-port" => 443,
           "scheme" => "http",
           "secure" => false,
           "socket-binding" => "http",
           "ssl" => undefined,
           "virtual-server" => undefined
       }
   }

   相同的结果可以用 cd 命令进入子节点并直接运行 read-resource 操作获得。

   例 3.13. 通过修改目录开放子节点资源

   [standalone@localhost:9999 /] cd subsystem=web
   

   Copy to Clipboard Toggle word wrap

   [standalone@localhost:9999 subsystem=web] cd connector=http
   

   Copy to Clipboard Toggle word wrap

   [standalone@localhost:9999 connector=http] :read-resource
   {
       "outcome" => "success",
       "result" => {
           "configuration" => undefined,
           "enable-lookups" => false,
           "enabled" => true,
           "executor" => undefined,
           "max-connections" => undefined,
           "max-post-size" => 2097152,
           "max-save-post-size" => 4096,
           "name" => "http",
           "protocol" => "HTTP/1.1",
           "proxy-name" => undefined,
           "proxy-port" => undefined,
           "redirect-port" => 443,
           "scheme" => "http",
           "secure" => false,
           "socket-binding" => "http",
           "ssl" => undefined,
           "virtual-server" => undefined
       }
   }

3. 使用 recursive 参数在结果里包含活动的属性值。

   recursive 参数可以用来开放所有属性的值，包括非持久性的值、在启动时传入的值或其他在 runtime 模型里活动的属性。

   [standalone@localhost:9999 /]/interface=public:read-resource(include-runtime=true)

   Copy to Clipboard Toggle word wrap
   和之前的例子相比， include-runtime 请求属性会开放其他的活动属性，如发送的字节和 HTTP 连接器接收的字节。

   例 3.14. 用 include-runtime 参数开放其他活动的属性值。

   [standalone@localhost:9999 /] /subsystem=web/connector=http:read-resource(include-runtime=true)
   {
       "outcome" => "success",
       "result" => {
           "any" => undefined,
           "any-address" => undefined,
           "any-ipv4-address" => undefined,
           "any-ipv6-address" => undefined,
           "inet-address" => expression "${jboss.bind.address:127.0.0.1}",
           "link-local-address" => undefined,
           "loopback" => undefined,
           "loopback-address" => undefined,
           "multicast" => undefined,
           "name" => "public",
           "nic" => undefined,
           "nic-match" => undefined,
           "not" => undefined,
           "point-to-point" => undefined,
           "public-address" => undefined,
           "resolved-address" => "127.0.0.1",
           "site-local-address" => undefined,
           "subnet-match" => undefined,
           "up" => undefined,
           "virtual" => undefined
       }
   }
