Database Autonomy Service:Use the basic features of DAS

Database Autonomy Service (DAS) provides rich basic features for regular database O&M and management. This topic describes how to use the basic features of DAS by using an example. The example shows how to view the performance trends of various metrics of an ApsaraDB RDS for MySQL instance. For more information, see Supported database engines and features.

Procedure

1. Log on to the DAS console.

2. In the left-side navigation pane, click Instance Monitoring.

3. On the page that appears, find the database instance that you want to manage and click the instance ID. The instance details page appears.

4. In the left-side navigation pane, click Dashboard.

   • On the Performance Trends tab, view the trend charts of metrics within a specific time range.

     • Click More Metrics and select the metrics that you want to view.

       Note

       Click the icon to the right of a metric name to view details of the metric.

     • Drag and select a time range in the trend chart of a metric and click Diagnose to analyze the trend of the metric within the selected time range.

     • Click Details in the trend chart of a metric to view the enlarged trend chart. You can change the time range to view the trend of the metric within the specified time range.
