建议所有内容交给大模型优化下，以下是大模型优化的结果：
查看配置项
有两种方式能够查看 BE 配置项：
-
通过 BE 的 Web 管理界面查看
在浏览器中打开 BE 的 Web 管理界面: http://be_host:be_webserver_port/varz
-
通过命令行查看
可以在 MySQL 客户端中，通过以下命令查看 BE 的配置项，具体用法参照 SHOW-CONFIG：
SHOW BACKEND CONFIG;结果中各列含义如下：
- BackendId: Backend 节点 ID。
- Host: Backend 节点 IP。
- Key: 配置项名称。
- Value: 配置项的值。
- Type: 配置项值类型，如整型、字符串。
- 是否可以动态配置：如果为 true，表示该配置项可以在运行时进行动态配置。如果为 false，则表示该配置项只能在 be.conf 中配置并且重启 BE 后生效。
