    Database Autonomy Service:Performance trends

    Last Updated:Jun 13, 2023

    Database Autonomy Service (DAS) allows you to view the performance trends of database instances based on a wide spectrum of performance metrics and customize charts. DAS also allows you to specify a time range and manually perform diagnostics on the instances in the specified time range. DAS provides powerful diagnostic capabilities to help you understand the health status of your instances.

    Prerequisites

    A database instance is connected to DAS and is in the Accessed state. For more information, see Access instances.

    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 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.

          Note

          You can click the 指标.png icon next to a metric to view the details of the metric.

        • Select an event level. If DAS detects events at the specified level, the detected events are displayed in the CPU Utilization trend chart.

          You can click an event in a trend chart to view the diagnostic result in the event details.

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

        • 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 for a metric within different time ranges.

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

      • On the Custom Chart tab, 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 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.
