 5. auth: User name and corresponding permission information
-6. jobs:
+6. jobs: show statistics of all kind of jobs. If a specific `dbId` is given, will return statistics data of the database. If `dbId` is -1, will return total statistics data of all databases
 7. bdbje: To view the bdbje database list, you need to modify the `fe.conf` file to add `enable_bdbje_debug_mode=true`, and then start `FE` through `sh start_fe.sh --daemon` to enter the `debug` mode. After entering `debug` mode, only `http server` and `MySQLServer` will be started and the `BDBJE` instance will be opened, but no metadata loading and subsequent startup processes will be entered.
 8. dbs: Mainly used to view the metadata information of each database and the tables in the Doris cluster. This information includes table structure, partitions, materialized views, data shards and replicas, and more. Through this directory and its subdirectories, you can clearly display the table metadata in the cluster, and locate some problems such as data skew, replica failure, etc.
 9. resources : View system resources, ordinary accounts can only see resources that they have USAGE_PRIV permission to use. Only the root and admin accounts can see all resources. Equivalent to [SHOW RESOURCES](./SHOW-RESOURCES.md)

+6. jobs ：各类任务的统计信息，可查看指定数据库的 Job 的统计信息，如果 `dbId` = -1, 则返回所有库的汇总信息
 7. bdbje：查看 bdbje 数据库列表，需要修改 `fe.conf` 文件增加 `enable_bdbje_debug_mode=true` , 然后通过 `sh start_fe.sh --daemon` 启动 `FE` 即可进入 `debug` 模式。 进入 `debug` 模式之后，仅会启动 `http server` 和 `MySQLServer` 并打开 `BDBJE` 实例，但不会进入任何元数据的加载及后续其他启动流程，
 8. dbs ： 主要用于查看 Doris 集群中各个数据库以及其中的表的元数据信息。这些信息包括表结构、分区、物化视图、数据分片和副本等等。通过这个目录和其子目录，可以清楚的展示集群中的表元数据情况，以及定位一些如数据倾斜、副本故障等问题
 9. resources : 查看系统资源，普通账户只能看到自己有 USAGE_PRIV 使用权限的资源。只有root和admin账户可以看到所有的资源。等同于 [SHOW RESOURCES](./SHOW-RESOURCES.md)
