   Parameter	Description
   Component Name	The unique name of the MySQL exporter. The name must meet the following requirements: It can contain only lowercase letters, digits, and hyphens (-), and cannot start or end with a hyphen (-). It must be unique. Note If you do not specify this parameter, the system uses the default name, which consists of the exporter type and a numeric suffix.
   MySQL URL	The URL that is used to access the MySQL database. Note The URL of the MySQL database that is deployed in ACK, ECS, or ApsaraDB RDS is automatically displayed in the drop-down list.
   MySQL Port	The port number of the MySQL database. Example: 3306.
   Username	The username and password of the MySQL database. Important We recommend that you do not use an administrator account to avoid data breach risks.
