Configuring Monitoring by Seconds

RDS for MySQL supports monitoring by the second. You can set the monitoring interval to 1 second or 5 seconds to view the metric values.

To apply for the second-level monitoring permission, submit a service ticket by choosing Service Tickets > Create Service Ticket in the upper right corner of the management console.

Enabling Monitoring by Seconds

  1. Log in to the management console.
  2. Click in the upper left corner and select a region and a project.
  3. Click in the upper left corner of the page and choose Database > Relational Database Service. The RDS console is displayed.
  4. On the Instance Management page, click the target DB instance.
  5. In the navigation pane on the left, choose Advanced O&M.
  6. On the displayed page, click the Real-Time Monitoring tab and click next to Monitoring by Seconds.
  7. In the displayed dialog box, select a collection period and click Yes.

    Monitoring by Seconds will be automatically disabled for DB instances with fewer than 4 vCPUs. After you enable this function, monitoring data will be reported again and will be displayed by the second, starting approximately 5 minutes after the function was enabled.
