Viewing Performance Metrics

DBA Assistant allows you to view the performance metrics of your DB instance. Historical trends of performance metrics within a specified time period help you learn about the status and resource usage of your DB instance. If any alarm is reported, you can take actions timely.

Procedure

Log in to the management console.
Click in the upper left corner and select a region and a project.
Click in the upper left corner of the page and choose Databases > Relational Database Service.
On the Instances page, click the DB instance name.
In the navigation pane, choose DBA Assistant > Real-Time Diagnosis.
Click the Performance tab to view the performance metrics of your instance.
- By default, Comparison by Date is selected. The system automatically displays the comparisons of the performance metrics between the last hour and the same time period of the previous day for your instance.
  You can also select different days and time ranges and click View Details.
- If you deselect Comparison by Date, you can view the dynamic trend of each performance metric of your instance in a specified period of the current day. By default, the metric trends in the last 5 minutes are displayed. You can select Last 10 minutes, Last 30 minutes, or customize a time period and click View Details. The system automatically refreshes and displays the dynamic trend of each metric of the instance in the specified time period.
