Database Autonomy Service (DAS) provides the performance trends feature for ApsaraDB RDS for PostgreSQL. You can use this feature to view performance trends over specific ranges, compare performance trends, and customize charts to view the performance trends of your ApsaraDB RDS for PostgreSQL instance.

Prerequisites

Your ApsaraDB RDS for PostgreSQL instance runs ApsaraDB RDS for PostgreSQL High-availability Edition.

Procedure

  1. Access RDS Instances, select a region at the top, and then click the ID of the target RDS instance.
  2. In the left-side navigation pane, choose Autonomy Service > Dashboard.
  3. On the page that appears, perform the following operations based on your business requirements:
    • On the Performance Trends tab, view the charts for performance trends in a specified time range based on the metrics.
      • Click More Metrics and select the metrics that you want to view.
      • On a performance chart, drag-select a time range and click Diagnose to view diagnostic reports within the time range.
      • You can click Details in the trend chart of a metric to zoom in the trend chart. In this case, you can change the time range to view the trend of the metric over the specified time range.
    • On the Performance Trend Comparison tab, view the comparison of performance trends in a specified time range based on the metrics.

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

    • On the Custom Chart tab, you can create dashboards to display the performance metrics that you want to view. When you create a chart, you can specify multiple performance metrics that you want the chart to display. This way, you can analyze metrics that are displayed on the dashboards and troubleshoot performance issues.
      Note You must create dashboards before you create charts. For more information, see Monitoring dashboards.
