You can use Database Autonomy Service (DAS) to identify the topology of an ApsaraDB RDS for MySQL or ApsaraDB for MongoDB instance and diagnose the topology of ApsaraDB RDS for MySQL databases. You can use the following methods to view the topology of a database.

Prerequisites

Instance monitoring - instance topology

  1. Log on to the DAS console.
  2. In the left-side navigation pane, click Instance Monitoring, and then select Topology.
    Note
    • The topology of an ApsaraDB for MongoDB instance is built based on the primary node.
    • The topology of an ApsaraDB RDS for MySQL instance is built based on the primary database.

Instance topology

  1. Log on to the DAS console.
  2. In the left-side navigation pane, click Instance Monitoring. On the Instance Monitoring page, find the instance you want to view.
  3. Click Performance in the Actions column corresponding to the instance, and then choose Performance Trend > Instance Topology.
