The instance management feature displays the information of the TencentDB instances supporting DBbrain so that you can conveniently manage database instances.

• For TencentDB databases, this feature mainly displays the basic information of database instances (instance name/ID, status, etc.) and their groups, exception alarms, health scores, and operations.
• For external databases, this feature mainly displays the basic information of database instances (instance name/ID, status, etc.), exception alarms, health scores, monitoring data collection, slow log collection, access methods, agent status, instance status, accounts, and operations.

Note：

Currently, instance management is supported only for TencentDB for MySQL (excluding the basic single-node instance) and external MySQL databases.
