    ApsaraDB for OceanBase:View optimization suggestions

    Last Updated:Oct 22, 2024

    The optimization center displays performance monitoring metrics for each tenant, as well as SQL-class and structural-class optimization suggestions. This topic describes how to view these optimization suggestions.

    Background information

    By default, the optimization center displays the results of the most recently successfully executed detection task. After the detection is initiated, the system will perform optimization detection on the top 100 SQL statements with the slowest response time during the query period, and evaluate whether there is room for optimization in the related tables and indexes.

    Procedure

    1. Log on to the ApsaraDB for OceanBase console.

    2. In the left-side navigation pane, choose Autonomy Service > Diagnostics Center.

    3. In the Instance Details section, click the name of the target instance.

      The system automatically redirects to the diagnostics center.

    4. In the left-side navigation pane, click Optimization Management.

      The system automatically displays the Optimization Suggestions tab.

      1. In the Tenant section, view the QPS, Average SQL Statement Processing Time, and CPU Percent of a tenant.

        1. Click Initiate Detection in the upper-right corner to start a detection task. The task detects SQL statements, tables, and indexes that match the rule within the specified time period and provides optimization suggestions.

          Note

          You can specify a custom period within the last 15 days as the time range for detection. The time range cannot exceed 24 hours.
