Database Autonomy Service (DAS) provides the dashboard feature for ApsaraDB RDS for MySQL. This feature allows you to view the performance trends of an ApsaraDB RDS for MySQL instance based on various performance metrics. You can also create custom charts to view performance trends. This feature provides diagnostic capabilities to detect events on your RDS instance at the earliest opportunity and then diagnose the events to analyze root causes of performance issues and provide handling suggestions. This feature also allows you to select a time range for manual diagnostics. This helps you understand the performance of your RDS instance.

Prerequisites

Your RDS instance runs one of the following MySQL versions and RDS editions:
  • MySQL 8.0 on RDS High-availability Edition or RDS Enterprise Edition
  • MySQL 5.7 on RDS High-availability Edition or RDS Enterprise Edition
  • MySQL 5.6 on RDS High-availability Edition
  • MySQL 5.5 on RDS High-availability Edition

Procedure

You can use one of the following methods to go to the Dashboard page:

Method 1:

  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.
    Performance Trends
    • On the Performance Trends tab, you can view the trend charts of metrics within a specific time range.
      • You can click More Metrics and select the metrics that you want to view.
      • You can 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.
      • You can click Details in the trend chart of a metric to expand the chart. You can also change the time range to view the change trends of the metric within different time ranges.
      • You can select the severity levels of events. If events of the selected severity levels are detected, the system displays the detected events in the MySQL CPU Utilization/Memory Usage and Session trend charts.

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

        Event Monitoring
    • On the Performance Trend Comparison tab, you can view the comparison of performance trends for a metric within different time ranges.

      You can click More Metrics and select the metrics that you want to view.

    • On the Custom Chart tab, you can create custom dashboards to display the metrics that you want to view. When you create a chart, you can specify multiple metrics that you want the chart to display. This helps you analyze metrics that are displayed on the dashboard and resolve performance issues.
      Note Before you create charts, you must create dashboards. For more information, see Use the monitoring dashboard feature.
    • On the Exception Detection tab, you can view the results of exception detection and predictions for core metrics. For more information, see Performance anomaly detection.

      You can click More Metrics and select the metrics based on which you want to detect exceptions.

    • On the Instance Topology tab, you can view the topology of the instance.
