Database Autonomy Service (DAS) provides the cluster performance trend feature that helps you manage database instances in batches. If you have multiple database instances that use the same database engine, such as MySQL, MongoDB, and Redis, you can organize the database instances into a cluster. This allows you to manage the performance trends, rank the slow SQL queries, and rank the storage space of instances for each cluster.
Notes: A database instance can belong to only one cluster.
- You remain logged on to the DAS console.
- The target database instance is connected to DAS, and the target database instance is in the Accessed state. For more information about how to connect database instances, see Connect database instances.
In the left-side navigation pane of the DAS console, click Clusters. On the page that appears, find the target cluster, and click Monitor in the Actions column.
On the page that appears, you can view the details of the performance trend for the cluster:
To view the performance details of each instance that is included in the cluster, click Drilldown on the performance chart of the target performance metric.
In the dialog box that appears, you can view the performance details of each instance. The following figure shows an example.
