You can use the cluster management feature of DAS to combine instances of the same database engine into a cluster, and then view information about these instances such as performance trends, slow query log trends, and global storage usage at the cluster level.

Prerequisites

The following database engines are supported:
  • MySQL
  • Redis
  • MongoDB
  • PostgreSQL
  • PolarDB MySQL
  • PolarDB PostgreSQL
  • PolarDB Oracle
Note MySQL, Redis, MongoDB, and PostgreSQL databases can be Alibaba Cloud databases or self-managed databases. A database instance can belong to only one cluster.

Procedure

  1. Log on to the DAS console.
  2. In the left-side navigation pane, click Clusters.
  3. On the Clusters page, click Add Cluster in the upper-right corner.
  4. In the Add Cluster dialog box, configure the parameters listed in the following table. Then, click Save.
    Parameter Description
    Cluster Name The name of the cluster.
    Select Environment Available options: Development environment, Test environment, and Production environment.
    Select Engine The database engine that supports cluster management.
    Cluster Description The description of the cluster.
  5. In the Actions column corresponding to a cluster, you can perform the following operations on the cluster:
    • Edit: modifies information of the cluster, such as the cluster name, environment, engine, and description.
    • Delete: removes the cluster from the cluster list.
    • Monitor: displays the Cluster Overview, Dashboard, and Cluster Storage settings of the cluster.
