After creating a globally-active database instance group, you can view its basic information, topology diagram, and configuration list on the details page.
Prerequisites
Procedure
Go to the globally-active database page. In the instance group list, click an instance group ID. The details page opens, where you can view the basic information, topology diagram, and configuration list of the instance group.
Basic information
Basic information about an instance group includes the Instance group ID, Name, Type, Database Engine, Creation time, Status, and Region.
Topology diagram
The topology diagram visualizes the instance group, showing the links between the primary and secondary instances, their statuses, and other basic information. For example, the topology diagram of a three-node instance group might show a primary instance in the China (Hangzhou) region (availability zone J) with a status of Running, and two secondary instances in the China (Beijing) region (availability zone L) and the China (Shanghai) region (availability zone L). The primary instance is connected to each secondary instance through a DTS two-way synchronization link. Each instance displays its ID, name, region, availability zone, and status. Each synchronization link displays its DTS task ID and synchronization type.
-
Click the instance ID to view the instance details in the RDS console.
-
Click the synchronization link ID to view the link details in the DTS console.
Configuration list
The instance group configuration list includes the RDS instance list and the DTS instance list:
RDS instance list
The RDS instance list displays all instances in the instance group and their corresponding Status, Region/availability zone, Role, and Creation time.
-
Click an instance ID to view the details of the instance.
-
In the upper-right corner, click Add secondary instance to add a new secondary instance to the instance group. Or, in the Actions column, click Remove to remove a secondary instance.
DTS instance list
The DTS instance list displays all DTS synchronization links in the instance group, along with their synchronization direction, Region, Status, Synchronization Latency, and Creation time.
-
Click the Instance ID or View Details of a synchronization link to view its details.
-
When you remove a secondary instance from the instance group, the associated DTS synchronization link is automatically released.
