Developing or O&M Databases

DAS provides Development Tool and Intelligent O&M to help you maintain and manage DB instances.

Development Tool is an easy-to-use database client. It provides diverse database development functions, including data and table structure synchronization, online editing, and intelligent prompts for SQL input.

Intelligent O&M is mainly designed for database administrators (DBAs) and provides the following database O&M functions: host and instance performance analysis, slow and all query logs analysis, real-time database performance analysis and diagnosis, historical data analysis, and more.

This section describes how to use DAS for RDS for MySQL instances.

    • Specifying metrics

      You can check metrics and specify metrics to create charts.

      Figure 5 Specifying metrics
    • You can select the classic, OOM diagnosis, read replica delay diagnosis, full space diagnosis, CPU jitter diagnosis, and large transaction identification and diagnosis views. Each view corresponds to a batch of preset metrics, which can help you diagnose DB instance problems.
      Figure 6 Querying metrics by view
    • View the trends in metrics in the same time range on different days.

      You can select Select Date for Comparison, and specify the target comparison date and metrics to view trends in the metrics at the same time on different days.

      You can place the pointer over a time point in the trend chart to view the metric at the time point on different days.

    • View real-time performance of the instance.

      You can deselect Select Date for Comparison, set a time range or select 1h, 3h, or 12h to view real-time metrics of the instance.

      You can place the pointer over a time point in the trend chart to view the metric at this time point.

    • Customize the time range you wish to view.
      After clicking , you can drag the mouse on the chart to select a period of time. Then, you can click Analyze to go to the Slow SQL Logs page and analyze slow query logs in the time period.
