To further enhance product monitoring performance and optimize the monitoring system architecture, Tencent Cloud will comprehensively optimize and upgrade the monitoring metric collection framework of TencentDB for SQL Server. The details are as follows:

After optimization, the new monitoring architecture can significantly improve the performance metric collection efficiency, reducing the CPU time slice consumption by 90% compared to the old architecture.

Release start time: May 13, 2026 (UTC+8).

Implementation method: The switchover between the old and new monitoring systems will be performed during the instance maintenance window within the release period.

During the switchover, instances with different architectures will experience temporary impacts:

Instances with cloud disk architecture: Monitoring gaps of approximately 30 seconds and brief CPU spikes may occur.

Instances with local disk architecture: Monitoring gaps of approximately 1 minute may occur.

The above impacts only affect monitoring data display and do not affect the normal business operations or database services of the instances.

If you encounter any issues during the release, please 

We recommend that you monitor changes in monitoring data accuracy after the optimization is complete.

Thank you for your trust and support for Tencent Cloud.
