| Parameter Name | Dimension Name | Dimension Description | Format |
|---|---|---|---|
| Instances.N.Dimensions.0.Name | InstanceId | Database instance ID | Enter a string-type dimension name, such as topicId |
| Instances.N.Dimensions.0.Value | InstanceId | A specific database ID | Enter a specific instance ID, such as topic-i4p4k0u0 |
| Instances.N.Dimensions.1.Name | InstanceType | Database instance type | Enter a string-type dimension name, such as InstanceType |
| Instances.N.Dimensions.1.Value | InstanceType | Database instance type. The default value is 1: InstanceType is set to 1, it means to obtain the monitoring data of the Master.
